This is going to take some reading and discussing to fully understand, so as questions arise, feel free to ask.
VOLCANOES, EARTHS HISTORICAL THERMOSTAT
Only large scale eruptions (VEI-4 and greater) that could alter the planets weather systems were researched and used as the base line for this research. Any referance to eruptions in this chapter are to be associated to only these large eruptions. These large scale eruptions alter weather patterns and cool the planet and act as a pressure relief valve for the planet. Specifically, when they alter the weather conditions on the surface, their should be a condition and cause for such an event.
Because temperatures were never recorded until Daniel Farienhieght came up with a way to measure and record variables in temperatures in 1724, an alternative method of research was selected.
The earth has a molten core sealed within a surface that we call the crust. Because of the unique features that a liquid posses when it is in a sealed container the research was new and unique. To understand the differences take two bottles of water and open only one of them. Place them both in the microwave on high and watch how they differ in their reaction. A liquid, in a sealed container, even the earth, increases in pressure until eruption occurs. This is not because we made this, its the planets principle of physics that we duplicate in the microwave. Persuing this avenue of research revealed a vast array of new discoveries that brings about many explanations to our planets heating and cooling cycles and a past historical timeframe that aids us in understanding these cycles and their causes.
Current research has aided greatly in the forensics of past eruptions, but records and accuracy become more obscured as we travel back in time. This happens as volcanic eruptions, time and erosion all take their toll. Notable time periods would be prior to 1492 in both North and South America, Iceland prior to 874, Australia region prior to 1788, and the nothern Pacific region including Alaska and Russia prior to 1800. Many of these historical events in Asia and Europe have a written record allowing scientists to examine these eruptions in greater detail. Information about the forensics involving the examination of past eruptions can be found at the Smithsonian Institute and is known as the, “Global Volcanism Program.” Because this data was raw and unmanipulated from volconologists, the accuracy for this review is an optimum data base.
The data was placed out over time lines and seperated by the tectonic plate associated with the eruption. Thermyl Dynamic’s tells us that if you have a large container of fluid and heat only one area, the heat and pressure will be the greatest at the source of the heat. This indicates that if a plate was to heat for any reason, the pressure would be greatest under the plate heating and a volcanic eruption will occur at the weakest location to the source of the heat along its plate. Like a pan on the stove that is sealed and heating, the weakest point no matter where the location, will give way if the heat continues. By plotting these eruptions there are clearly definable date lines where there was a distinct rise and fall in eruptions. These occurances are what is examined, and the causes of them.
Volcanoes have always been a part of the planets history. They offset additional heating that may result from an increased solar output, or perhaps a meteor wiping out a large
portion of the earths land surface. They can be considered a pressure relief valve the same way you will find man using it to release pressure to ensure the safety of a machine. In regards to the Earth, they keep us from literally blowing apart.
As these records were plotted out there was enough documented eruptions to begin plotting the rise and fall in these large volcanic erutions as far back as 700 AD. Although there is further research that could be done going further back, there has not been any research as of this time and further forensics and carbon dating would be needed.
All data is aquired from the “Global Volcanism Program” from the Smithsonian Institute and is the site that the USGS recommends.
All volcanoes are graphed per decade
ex. year 1700 is all volcanic activity that occurred from 1/1/1700 to 12/31/1709.
In the following graphs there are three periods of time that need to be considered. These period’s of time were specific times of cooling due to the suns decrease intensity upon the planets surface, two natural and one manmade by accident.
Maunder Minimum (1645 – 1715)
Dalton Minimum (1790 – 1803)
Pollution and its impact from post WWII (1940 until 1970 and shortly after)
NORTH AMERICA PLATE
When eruptions occur in this region, specifically near the Gulf of Mexico, they have a direct impact on the oceans jet streams affecting the people inland greatly. They shade the Gulf and reflect a great amount of solar radiance back out into space. This in turn cools the Gulf stream allowing the Arctic cold to have more momentum and alter the rains. This can also create major storm systems and flooding in some areas, while bringing droughts to other regions.
In North and South America the year that these large eruptions have occured is known with 100% accuracy since 1800, and only one questionable eruption since 1500.
Before 1570 there are many uncertain dates averaging a plus and minus range of about 100 years. Because of specific groupings found, and relying on the endless hours of scientists attempting to get these dates correct, we graphed them out as they are written.
When graphed out it was found that the Lower 48 states, Mexico, Central America, Carribean, Gallopagose, Columbia, Peru and Ecuador had a pattern of working together. As a result this region was combined.
ERUPTIONS FROM 700 to 1009, NORTH and SOUTH AMERICA
y-axis is the number of eruptions, x axis is years 700 AD to 950 AD.
As we look this far back in time there was a notable grouping of eruptions during this period. Because of the vast numbers of eruptions, this was flagged as our starting point.
In this graph we can see that there were a total of 12 eruptions during a 260-year period, a 46% chance of an eruption every decade. From the period of 720 AD through 829 AD, 8 of these major eruptions took place, a 72.7% average of having an eruption per decade. Over the remaining 150 years there were 4 eruptions dropping the eruption rate down to 26.6% per decade.
This is also the period of time when Archeologists acknowledge that the Mayan Empire collapsed. Recent studies have shown that a cataclysmic breakdown occurred just after these eruptions took place. Archaeology has determined over recent years that they had exhausted their resources by stripping the land for the agricultural needs of the vast population and for the needs in building and construction. Such events could have easily caused a vast migration of the people to another area with adequate resources.
ERUPTIONS FROM 830 to 1019 NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
After the rise in eruptions we see the eruptions from 830 until 1019 (2 in 930) lowered to only three over a 190-year period. This comes to an average eruption rate of 15.7% per decade. If we consider this average we can see that in the previous graph that eruptions had multiplied nearly 4.6 times greater than this period.
ERUPTIONS FROM 1000 to 1279 NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
After 240 years from the end of the previous rise in eruptions we see them elevate again. During this 280-year period of time there were 9 major eruptions. From 1020 – 1089, a 70-year period, 6 eruptions occurred placing the average eruption rate at 85% per decade. Over the remaining 210 years there were 3 eruptions with an average eruption rate of 14.2% per decade. This is more than 5 ˝ times the normal eruption rate.
A civilization known today as the “Anastasia” were known to have existed prior to this time. Current research has now established that it was during this period of time when the inhabitants vanished. Archeologists have determined that they had wiped out their resources and altered their land for agricultural use and construction material to support a very large-scale population. There is a 200-year time frame (820 – 1020) from the end of the previous rise in eruptions to the reoccurrence of these eruptions again. The eruption of 1070 in Arizona was probably the eruption that may have finally forced the migration of the people to new land after years of troubles.
ERUPTIONS FROM 1100 to 1329 NORTH and SOUTH AMERICA

y-axis is number of eruptions, x-axis is year.
During this 230-year period there were 3 eruptions with a decade average eruption rate down to 13%. This quiet period, as the other previous period, results in a 6.5 times the normal eruptions rate that occurred prior to this lull in activity.
ERUPTIONS FROM 1310 to 1529 NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
In this graph there were 12 total eruptions over a 200-year period. From 1330 – 1389 there were 8 eruptions in 60 years, an average eruption rate of 133% per decade. This is 10 times the eruption rate in the previous years leading up to this date.
The 140 years that followed this period experienced 4 eruptions resulting in 28% chance of an eruption every decade. This is nearly 5 times less the normal eruption rate than 1330 - 1389. The period of calm between these eruptions was from 1090 to 1330, a 240-year period.
There is enough time between eruptions for people to have migrated, repopulated and stripped the land of its resources again.
ERUPTIONS FROM 1410 to 1579 NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
During this period we can see that 7 eruptions occurred over this 170-year period. This is an average eruption rate of 41% per decade, nearly 3 times the previous low averages registered previously.
This is the period of time when we find that both the Aztecs and Incas emerge. This eruption data indicates that the people of this era may have not evacuate their lands as a result of the eruptions that occurred earlier as the Mayan and Anastasia once did, but their population must have struggled greatly. Perhaps there was wars or diseases affecting the people during this time causing an extended period of a small population growth. Knowing that 2 large empires emerged during this period of time, it should also appear in the eruptions later.
Beginning in this graph, specifically 1570, there is 100% accuracy to the year of the erutpion.
ERUPTIONS FROM 1510 to 1709

y-axis is number of eruptions, x-axis is year.
In this graph there is a 200-year period of time and 15 major eruptions. From 1570 – 1610, a 50-year period, there was 11 major eruptions. This is an eruption rate of 322% per decade, or nearly 8 times greater than the previous years. When considering the previous lulls of 13% we can see that this eruption rate is nearly 25 times greater than previous lulls in activity.
From 1390 – 1570, there is a 190-year period since the end of the last set of eruptions. The continual eruptions remained at a slightly higher rate until 1570 indicating vast population depletion may have resulted during this period of time.
By the 1520’s the Inca and Aztec Empires were wiped out. These two large-scale populations had rapidly depleted their resources and the land was left barren to return to its natural form, but this was going to decades. The Europeans went through and ravaged the land and then left it for the years to come. The preliminary heat had already imbedded itself into the plate and the earth responded to mans alteration of the land. This also resulted in a quick reduction of eruptions shortly after. These events would have had vast impacts on the populations of the people. Eruptions in this region became silent from October 27, 1660 until August 27, 1717. This was the period of time when the Maunder Minimum occurred. (1645 - 1715)
ERUPTIONS FROM 1700 to 1870, NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
In this graph we can see 14 eruptions in 180 years with an average eruption rate of 77% per decade.
America’s first colony was established in 1607 at Jamestown. Just over 100 years later we begin to see this region slowly rise in eruptions again. Their was a lull in activity that preceded the Dalton Minimum (1790 – 1803) and then a higher than normal, yet stable eruption rate that remained throughout this period of time.
North America was being populated and cleared for its resources and can be seen by the higher than normal eruption rates during this period. Yet, this was also being offset by the massive decline in the population of the Native Americans from wars and diseases. In 1800 the heart of America remained in close proximity to the oceans, and western America was the land beyond the Appalachian Mountains. In 1800, there were no roads to connect them and people would take the waterways to access this part of the country due to the vast wilderness between them.
With the Louisiana Purchase in 1803, a vast wilderness was opened to be farmstead, and the continent would never look the same again. By 1860 the lower 48 states had been cleared to the prairies, and with the introduction of the industrial age, tractors and now the railroads, the vast wilderness and prairies was soon going to be gone.
ERUPTIONS FROM 1870 to PRESENT, NORTH and SOUTH AMERICA
y-axis is number of eruptions, x-axis is year.
The 1902 eruption of Pelee in the West Indies erupted 6 days apart and both were categorized as a level-4. Also, in 1982 the eruption of El Chichon in Mexico erupted twice a week apart, first as a VEI-4 then again as a VEI-5. From a thermal dynamics perspective of heat and pressure, such an eruption is significant and is marked as 2 separate eruptions. During this 140-year period we see that there are 18 eruptions. From 1880 thru 1919 there were 10 eruptions in a 40-year span. This is a 250% eruption rate per decade. This was then followed by 1920 – 1979 where the eruption rate declined to 4 eruptions over a 60-year period. This is an eruption rate of 66% per decade. This reduced these eruptions by 3.8 times their rate and began an era of cooling from 1920 to 1979 due to the vast amounts of air pollutants man was distributing into the air.
By 1880 the planet was reacting to man altering the land for agricultural and city developments. The US began to enter the industrial age and the introduction of the railroad, farm tractor and other machinery allowed us to clear and harvest vast quantities of land rapidly. What once took 200 years or more to convert the forest and prairies into agricultural land was now being accomplished in a few short decades. By the time WWI began in 1917, 44% of the entire land surface of the lower 48 states had been altered for agricultural use to support the war effort. This does not include rural areas.
The alterations of the land surface culminated into a mass migration of people from the Midwest shortly after these eruptions took place in the 1930’s. As it has happened many times in the past, 8 million people migrated out of the central US and took refuge in other areas of the country and is known today as the “Great Dust Bowl.” After this era the temperatures cooled as a result of the lack of solar radiance reaching the surface due to a build up of smog as a result of the industrial age.
The alterations of the land surface in the lower 48 states peaked at 59% in the 1950’s, and have declined since then for the conversion of farm fields to urban areas. According to our current ground heat, a rise in eruptions should begin soon.
Alaska and Russian Peninsula
This is a continual ridge that encompasses the northern Pacific from Alaska through the Kamchatka Peninsula of Russia. This makes up the Northwestern edge of the North American plate that branches over and is a part of Russia. When this area erupts the plume from the eruption is carried by the jet streams over the North Pacific from Russia and then the Arctic and Northern Canada increasing the Arctic’s intensity.
Alaska/Russia 750 - 1280
y-axis is number of eruptions, x-axis is year. During this 540-year period there were 9 eruptions, 6 that occurred between the years 950 – 1030. Excluding this 90-year period of time we have 3 eruptions in a 450-year time span, an average eruption rate of 6% per decade. In 950 a rise in eruption began and continued through 1030 totaling 6 eruptions in 90 years. This is an average eruption rate of 66% per decade. This is 11 times greater than the normal eruption rate.
This period of time also mirrors the rise in eruptions in the North American plate from 1020 to 1089. This rise began just prior to the decades of eruptions on the Southern section of the North America plate. What is also known is that the Anastasia were further north than the Mayan Empire.
Alaska/Russia 1280 - 1700

y-axis is number of eruptions, x-axis is year.
Here we have a 430-year span of time with 7 eruptions. There is a spike in eruptions occurring from 1540 to 1560, a 30-year period. This is a 100% average eruption rate compared to 4 eruptions in the remaining 400 years or 1% chance of eruption. This is a 100% rise in eruptions during this period of time.
The years 1540 – 1560 mirrors the North American eruption from 1570 –1610 during this period of time.
There were three eruptions during the Maunder Minimum (1645 – 1715). One eruption occurred in 1650 just as it began, one in 1690 in the middle, and one in 1712 just before it ended.
Alaska/Russia 1700 - Present
y-axis is number of eruptions, x-axis is year. During this 310-year period we have 35 eruptions. This had now risen to a 113% average eruption per decade. Since 1920 there have been 21 eruptions in 90 years, a 233% chance of an eruption, and since 1970 there have been 12 eruptions in 40 years, a 300% average eruption per decade. To put this into perspective, the chances of an eruption every decade went from 50% in the 1700’s, 60% in the 1800’s, 190% in the 1900’s, and now a 400% chance this past decade 2000 – 2009.
During the Dalton Minimum (1790 – 1803), and after a slow and methodical rise, they declined with the last one erupting in 1795 then remaining silent in 1825.
In the early 1800’s there were 3 areas in the world that were being altered for agricultural needs of the people in other nations. These were the lower 48 states of the USA that we have covered, and both Australia and Argentina. By the late 1800’s the industrial age was in full bloom and all these areas were being cleared rapidly.
CHILE
Chile, located in the southern hemisphere, has remained quiet for centuries with only an occasional eruption, until recently. The massive amounts of water that captures, stores, and releases a great amount of energy in this region creates less activity. The eruptions from this region send their plume over Argentina and the South Atlantic altering the jet streams in the southern hemisphere.

y-axis is number of eruptions, x-axis is year.
In this graph we can see the history and infrequent activity of the past eruptions in Chile.
This graph indicates that this region, unlike Columbia, Peru, and Ecuador, are not affected by the same magnitude and degree by the North American Plate. Chile remained quiet through all the previous eruptions that occurred in the north and through both the Maunder and Dalton Minimum’s.
1700 – present Chile

y-axis is number of eruptions, x-axis is year.
There are only 4 eruptions to have taken place from 700 – 1929, a 1230-year span. This is an eruption average of 3% per decade. In the last 110 years we see that 6 eruptions have taken place. This is an eruption rate of 54% per decade. This is 18 times greater than its previous norm.
From the late 1800’s and into the early 20th century much of the land in Argentina was altered for the agricultural needs, specifically for England. Today, 60% of their land has been altered for agricultural needs.
AUSTRALIA
On the eastern edge of the Australian plate we find the New Zealand region. To the northeast you will find the New Guinea region that could be influenced by the much larger Asian plate, and Indonesia on the northwest that is directly affected by the Asian and Australian plates.
Due to the population rise in China and its direct effect on the Indonesia region, we will remove this influence from the graph detailing a more direct impact man may have had on the Australian Plate.
This region has 100% accuracy to the year dating back to 1800.
AUSTRALIA 700 AD to PRESENT

ERUPTIONS, Australia 1630 – Present

y-axis is number of eruptions, x-axis is year.
Here we can see a definable decline in eruptions after February of 1660, shortly after the Maunder Minimum (1645 – 1715), and with the exception of one eruption in 1720, eruptions remained silent until 1800. With one eruption in 1800, a decade after the Dalton Minimum began (1790 – 1830), we begin to see a gradual rise beginning in 1840 that carries on to this day.
In 1778 the first settlements began In Australia and throughout the 1800’s farming increased, primarily by hand. Although there is a rise in eruptions prior to settlement, the New Guinea Region is on the northern edge and is buffered by the Philippine and Asian Plates. As a result, Chinas population growth has some influence on these regions specifically due to the massive growing population in China during this time.
During the mid 1800’s the railroads came through and much of the interior was settled and altered for agricultural purposes, specifically for England and Europe’s growing population. By 1880 a vast amount of land had been altered for agricultural needs. During the pollution era of the northern hemisphere we do find a dip in the 60’s and 70’s, at least 2 decades later than those eruptions in the northern hemisphere subsided. The cooling in the northern hemisphere would have taken decades to impact the southern hemisphere through the oceans jet streams.
By the 1960’s, more than 60% of the entire landmass of Australia was altered from its natural condition to support the world’s demand for food that continues to today.
EUROPE
Iceland is a great influence of weather over the European and Asian plates. When an eruption occurs, as it did in 2010, the winds blow the ash plume over Europe and Northern Russia. These eruptions increase the Arctic strength offering vast cooling over the region and alterations in the oceans normal jet streams. Jet stream alterations can cause massive flooding in some areas, while withholding typical or normal rains from another.
ERUPTIONS, Europe 800 – Present

y-axis is number of eruptions, x-axis is year.
This graph covers the European plate for the last 1,310 years with the exclusion of recent eruptions, 2010 and after. The blue line is a 40-year running average of these eruptions. Due to historical data available there is 100% accuracy to the year of eruptions back to 1550 in this region. Iceland was first settled in 874 making this data far more accurate after this date.
ERUPTIONS Europe 800 - 1400
y-axis is number of eruptions, x-axis is year.
During this 410-year period there were 15 major volcanic eruptions around the European Plate. From 1210 to 1269 there were 5 major eruptions with an 83% average of an eruption every decade. Excluding these years we can see that the average for the remaining 340 years is. 29% per decade, nearly 3 times less.
From 950 to 1250 is known as the “Medieval Warming” and is associated to the great European expansion when there was a massive population growth and industrial boom in Europe. From 980 to 1089 there were no eruptions that occurred maintaining a stable environment for Europe. Afterwards we see three eruption taking place up to 1209. The average eruption rate for this time frame was 13% per decade, 6.4 times the eruption rate that was to follow. Much of the resources of the continent during this time were wiped out for agricultural use to supply the expanding population and construction. In addition, because coal was not readily used, wood was needed for heat.
Current studies conclude that glacier expansion of the Alps began during this period of time and is making the science community rethink their position on the date in which the “Little Ice Age” began.
According to known history, it took man 210 years, as this graph indicates, to populate, expand and deplete the lands resources by hand before resulting in a rise in volcanic eruptions.
ERUPTIONS, Europe 1400 – Present

y-axis is number of eruptions, x-axis is year.
In the early 1300’s the “Black Death” hit Europe. Estimates are as much as ˝ the population perished as a result of this disease. From 1350 – 1420 there was a steep decline in the population and many farms were left vacant to grow for the years that followed but it was going to take time to grow and for the heat to dissipate. We see the eruptions peaking in the 1440’s before stabilizing again, but at a higher rate.
The population began rising again in the mid 1500’s as the population began to expand to its previous levels. Farmland that was left to grow was being plowed once again, and the eruptions began to rise.
Eruptions began to decline in 1670, just after the Maunder Minimum began (1645 – 1715) and continued at a low rate while the population continued to rise. Then there was a quick emergence in 1720 before stabilizing again and then going silent from 1790 – 1839 during the Dalton Minimum (1790 – 1830).
Because Iceland is along the European and American plate, either plate can cause a rise in the eruptions in Iceland. Due to the level of alteration of the American plate in the mid to late 1800’s, the American plate may have influenced some of these eruptions. These eruptions peaked during the same period of time as the American Plates in 1870 and 1900. All eruptions ended on March of 1947 as a result of WWII and the years of pollution, until recently.
ASIA
Eruptions along the Asian plate send its plume out over the ocean with the trade winds. This can affect the weather greatly in these regions causing alterations in typical rainfalls causing droughts in some areas while flooding others. Any cooling they receive is not from blocking the radiance over their soil, but alterations in the oceans jet streams.
Indonesia is along the southern edge and resides along the equator against the Australian Plate and intersects at New Guinea with the Philippine Plate. This is the region plotted in the following graphs.
Compare this with the past history in the following graph. By now it should be obvious as to the approximate date that we would see the population of China expand and the depletion of the areas resources by this graph. The Black is the total amounts with the bold black line indicating a 40-year average timeline.
ERUPTIONS 1000 – PRESENT, China and SE Asia

y-axis is number of eruptions, x-axis is year.
Of all the volcanic eruptions in this area, only 12 of them have a questionable date from 1000 to 1800, and since 1800 is 100% accurate. Japan has been one of the most identifiable areas maintaining written records back to this era.
ERUPTIONS, China and SE Asia, 900 – 1570

y-axis is number of eruptions, x-axis is year.
From 900 to 1570 there were 13 eruptions in this 680-year period, making this an eruption rate of 19% average per decade. Of these 13 eruptions, 8 have a variable eruption date in this era.
ERUPTIONS, China and SE Asia, 1570 - 1820

y-axis is number of eruptions, x-axis is year.
Of these eruptions, only 4 have a variable eruption date while the remaining are known to the year with 100% accuracy.
During this time there were 34 eruptions during this 260-year period with an overall average of 106% eruption rate per decade.
After the eruptions occuring in the 1640’s there is a gradual descrease in eruptions until 1720 when eruptions became silent. This time period matches the Maunder Minimum (1645 – 1715).
The decade after this we begin to see a gradual rise peaking in 1760 and then declining until no eruption took place in 1790’s and then spiked in the 1810’s. This period was a time of rapid population growth in the region even though the Dalton Minimum had begun in 1790.
SE ASIA, ERUPTIONS FROM 1820 - 2000

y-axis is number of eruptions, x-axis is year.
After a spike in eruptions in the 1810’s they began to decline until there was only one eruption in 1831 and no eruptions again until 1853. This is the decade after the Dalton Mimumum ended in 1830. We then begin to see an oscillation in an upward momentum as the years progress until the 1930’s ended.
This region was highly active in WWII and there was a great deal of ordinances and emissions expelled throughout this time, including 2 nuclear bombs. We also see as a result that the eruptions in the region went silent until 1951 when multiple eruptions occurred until 1966.
After 1966 eruptions in this region ended, and began again in 1981. From 1966 until 1975 America engaged into a war with Vietnam. Today, it is well understood that the bombing in this region exceeded the tonage of ordances dropped during WWII, and again had impact on this region. Since this time it has been on a steady incline.
Since 1950, China and SE Asia have more than doubled their populations. In need of increased food supply, this regions resource have been drastically altered to provide food for the people, cities and developments. They have had 18 erupotions since 1950, or a 266% eruption average per decade.
JAPAN
The Island of Japan is in the previous calculations and graph, but due to its recent inactivity and its level of accuracy it is graphed here separately. In this graph we can go back to 1100 with 100% accuracy to the year. Japan is an Island on the eastern edge of the Asian plate and is buffered in the north with the western edge of the North American plate and the eastern edge is creates the ridge between the Asian and Philippine plate.

y-axis is number of eruptions, x-axis is year.
ERUPTIONS, Japan 1100 - 1600

y-axis is number of eruptions, x-axis is year.
From 1100 through 1600, a 510-year period of time, there were 6 eruptions. The average eruption rate for this period of time is almost 12% per decade.
ERUPTIONS, 1600 to 2000 Japan
y-axis is number of eruptions, x-axis is year.
From 1600 to 2009 there were 23 eruptions during this 400-year period of time. Since the December 24,1933 eruption, Japan has remained silent. So we can see that these eruptions actually occurred in a 334-year period that results in an eruption average of 65% every decade. This is 5 times the eruption average prior to this period. Japans eruptions grew with the population expansion of mainland Asia, specifically China. After WWII and two nuclear bombs, volcanic eruptions went silent in Japan. The war in Korea that followed WWII and the war in Vietnam through 1975 would have massive impacts. This is a clear indicator of the impacts of mans recent history and massive wars with large-scale bombings having an impact on eruptions by mimicking them. With the current earthquakes experienced in this region it appears that this area may become active again very soon.
All materials in the world follow this principle except one, water. This will be covered later. When the past 200 years of volcanoes were examined because their exact dates are all known, a pattern developed. There were 117 total eruptions, 4 with unknown dates to their eruptions. This gave us a total of 114 eruptions to examine and of these, 72 occurred above the 10th parallel north. When taking the Philippines, Russia, Japan, Alaska, the US, and south to the Caribbean excluding South America we find that 79% of these volcanoes occur during the first 6 months of the year, January through June. The northern climates of Russia and Alaska expand into July where they had 4 of the 5 noted in the following graph.
ERUPTIONS 1800 to PRESENT, NORTHERN HEMISPHERE

y-axis is total volcanic eruptions, x-axis is the month of eruptions
The North American Continent is about 3,000 miles long. If you take the expansion characteristics of granite you will find that one degree will expand the plate by 84 feet. As the planet tilts on its axis and heats, the plates expand. By July they are fully expanded in the southern region of the northern hemisphere and expand northward until the northern region is fully expanded by August. These volcanos are fishers between the tectonic plates and as they heat they expand and apply pressure onto these fishers acting as a shut off. As the plates cool through the fall they reach their maximum contraction stage in January from the lack of solar energy. When they cool they relieve pressure along these plates and if the internal pressure is high enough, and the crust is weak enough, an eruption occurs. When a plate is heated, there is additional pressure under the plate that results in a higher frequency of eruptions during these seasons.
The automobile’s cooling system mirrors this process. As your automobile heats
In the middle and southern zones we found no pattern associated with the time of the year. There were 36 total eruptions during this time and 19 occurred from January through June and 17 from July through December. Over the last 200 years and out of 114 eruptions, only 2 have occurred in the month of December worldwide.
Time after time mankind populates a plate, strips it for its agricultural use, it heats and builds pressure till she blows and alters the weather patterns in the affected region. The Mayan, Anastasia, Great Dust Bowl, Little Ice Age, over and over we have done this throughout our history, and we are doing it again only this time on a massive scale. It is actually simple, if we go out on a hot summers day in a swimsuit with no sun protection. You will sit in the sun and I will sit under the tree and we will see the results in the morning. Just as your skin will be warm to the touch in the moning, so does the earth warm when she is stripped. Its called, "Thermal Absorption" CO2 is a by-product of this and can also be verified simply by this...CO2 began to rise before the use of fossil fuels and continued to rise, even though the temperatures dropped, thus the CO2 argument wouldn't stand a chance of being found as the guilty culprit in the court of law, but today many have their money and reputatons riding on it.
