Volcanoes

Although there are thousands of volcanoes across the world, there are some that we all know of.

Located in  Honshu, Japan, Mount Fuji is one of the most well known volcanoes in the world, and is a stratovolcano. It has erupted 16 times since 781 AD, and the most recent was 1707. These were not small eruptions, most were moderate in size, although, five historic eruptions have caused major damage, but have had no fatalities.

 

One of the recent United States eruptions that most of us have heard of. It is a stratovolcano and is still active today. In 2004, it was stated that Mount Saint Helens fit the criteria to erupt again. When it erupted on on May 18th, an earthquake caused the side of the volcano to collapse. It also triggered an eruption that lasted 9 hours.

An ancient eruption that dates back almost 2000 years ago, and is a compound stratovolcano with two vents. It erupted on August 24, 79 AD, and buried three Italian cities, Pompeii, Stabiae, and Herculaneum. Pompeii is the city we normally hear about, and was buried under 10 feet of ash. There are cavities where bodies would have been buried, and the ruins were discovered on March 23, 1748 after the cleanup of a 1631 eruption.

Possibly the most dangerous volcano in the United States, it is a rhyolite caldera complex, the most destructive kind of volcano. It is 34 miles by 45 miles, a monster compared to other volcanoes. There are multiple vents leading to a large chamber of magma, and if it were to go off, in worse case scenerio it could possibly destroy half of the United States. It could erupt for 3 weeks straight, spewing ash into the sky, this would be enough ash to black out the skies of the United States, and some of this would make it's way over to Europe as well. The pyroclastic flow of this eruption would kill anyone within 2 miles.
