Supervolcano 

 

Volcanoes can be both very impressive and highly destructive. While most people are used to watching the big shows of lava spewing from volcanoes on TV and some while volcano watching during their vacations, no one can possibly be prepared to the amount of disaster that a supervolcano would cause. In recorded history no one has experienced the fury of a supervolcano first hand but it is believed the impact that such an eruption could have would be deadly not only to people in the vicinity, but even for people on the other side of the world.

Known Supervolcanoes (Yellowstone)

There are six supervolcanoes which are currently known by most people. The many visitors of Yellowstone Park may not realize it, but they are walking on top of one of the biggest threats to humanity.  To understand how massive an eruption from one of these volcanoes can be, we can look at what took place in the Yellowstone Caldera volcano that erupted 2 million years ago. The size of the eruption was so big that the amount of ash ejected was over 8,000 times the amount ejected by the 1980 eruption of Mount St. Helens.

Long Valley Caldera

The Long Valley Caldera is located in the eastern side of the state of California and it is second only to Yellowstone. It’s last eruption, though not as massive as the one in Yellowstone supervolcano could still cause tremendous damage to the population in the world; that eruption took place close to 760,000 years ago, and the result was 2,000 times the size of the eruption of Mount St Helens.

Valles Caldera

The Valles Caldera is located northern of New Mexico and its last supervolcano eruption happened over a 50,000 years ago. The effects of the supervolcano eruption at the Valles Caldera were felt as far as Iowa as some ash and rock landed all the way there.

Lake Toba

Lake Toba in Indonesia is big; in fact it is actually bigger than the Yellowstone caldera. The last time this supervolcano erupted was 74,000 years ago.  The eruption that was presented was 5,000 times larger than the Mount St. Helens eruption and it has been suggested by several scientists that this event was so massive that it changed the trajectory of humanity and resulted in what we see today.

Taupo Caldera

The Taupo Caldera is located in New Zealand and though now the view that you get is that s a spectacular lake, that lake was created by an eruption 26,500 years ago; the basin which was left after the eruption is what became the lake you see today. This massive monster is not a dead supervolcano. Volcanic activity can be observed in the area in the form of venting and hot springs.

Aira Caldera

This Caldera in Japan is pretty close to the city of Kagoshima. This is not a sleeping giant; in fact there are several earthquakes in the area caused by it and the Sakura-jima volcano is still active. Those are clear signs that the caldera is still active and it is a reason for concern for scientists.
