Super Volcano
A supervolcano or super volcanic eruption is a volcanic eruption
which is substantially larger than any volcano in historic times
(generally accepted to be greater than 1,000 cubic kilometers).
Supervolcanoes occur when magma in the Earth rises into the crust
from a hotspot but is unable to break through the crust. Pressure
builds in a large and growing magma pool until the crust is unable
to contain the pressure. Supervolcanoes are relatively new to
science, they were previously unknown due to the fact they do not
fit the stereotypical model of volcanoes.
Although there are only a handful of Supervolcanoes, super volcanic
eruptions typically cause a long-lasting change to weather (such as
the triggering of a small ice age) sufficient to threaten the
extinction of species, and cover huge areas with lava and ash.
How this relates to 2012, is the fact that not one supervolcano has
erupted in the past
74,000
years. We are long over due in terms of the cycle of these massive
beasts. The underwater volcanoes are increasing exponentially. The
harmonic tremors are also on a steep rise. A 74,000 year cycle of
devastating super volcano nears as we approach 2012. The December
2004 Tsunami epicenter points towards a possible site for the super
volcano.
According to some geologists, it is possible that the recent Tsunami
is precursor to a massive shift in tectonic plates and a super
volcanic eruption in that area dwarfing what happened even 74,000
years back.
The year 2012 is specially mentioned in many ancient civilizations
as something to be scared about. Many believe that will the year
when human civilizations will be threatened. It is the year some say
when the whole human civilization will change forever.
74,000 years back a massive volcano in Sumatra filled the earth’s
atmosphere with dark cloud for years. The event reduced the world
temperature by 8 to 10 degrees Celsius. Close to 80% of the living
beings including humans were dead on the earth. According legends
among Indonesia tribes, the calamity was accompanied.
The super eruptions can cause massive calamity devastating all
vegetations and farming in the earth causing massive starvation and
hunger.
According to some geologists, the next one is due around 2012 based
on that 74,000-year cycle. Many are pointing towards Yellow Stone
National Park in America where Earth’s crust is wafer thin in
geological scale.
Mount St. Helens has started erupting. The Geological calm of the
world is extremely disturbed. Tsunamis, Landslides, Minor
earthquakes in tune of thousands are shaking the whole world’s
tectonic plates.
Most countries are reporting unusual weather patterns and excessive
major and minor quakes. In many parts of the world lakes are losing
their water and manifesting a sinkhole. Mud volcanoes and geysers in
Yellow Stone National Park are manifesting excessive temperature
rise and increased frequencies of eruptions.
VEI-8 (Supervolcano) eruptions have happened in the following
locations.
* Lake Taupo, North Island, New Zealand - Oruanui eruption 26,500
years ago
* Lake Toba, Sumatra, Indonesia - 75,000 years ago
* Whakamaru, North Island, New Zealand - Whakamaru Ignimbrite/Mount
Curl Tephra 254,000 years ago
* Yellowstone Caldera, Wyoming, United States - 640,000 years ago
* Island Park Caldera, Idaho/Wyoming, United States - 2.1 million
years ago
* Kilgore Tuff, Idaho, United States - 4.5 million years ago
* Black Tail Creek, Idaho, United States - 6.6 million years ago
* La Garita Caldera, Colorado, United States - Source of the truly
enormous eruption of the Fish Canyon Tuff 27.8 million years ago
The Lake Toba eruption plunged the Earth into a volcanic winter,
eradicating an estimated 60% of the human population (although
humans managed to survive, even in the vicinity of the volcano), and
was responsible for the formation of sulfuric acid in the
atmosphere.
VEI-7 volcanic events, less colossal but still super massive, have
occurred in the geological past.
* Tambora, West Nusa Tenggara, Indonesia - 1815
* Baekdu Mountain, China/North Korea - 969 AD
* Lake Taupo, North Island, New Zealand - Hatepe eruption 181 C.E.
* Kikai Caldera, Ryukyu Islands, Japan - 6,300 years ago (4,300 BC)
* Campi Flegrei, Naples, Italy - 12,000 years ago (10,000 BC)
* Aira Caldera, Kyushu, Japan - 22,000 years ago (20,000 BC)
* Reporoa caldera, New Zealand - 230,000 years ago
* Aso, Kyushu, Japan - Four large explosive eruptions between
300,000 to 80,000 years ago
* Long Valley Caldera, California, United States - 760,000 years ago
* Valles Caldera, New Mexico, United States - 1.12 million years ago
