Volcanic eruptions in the ocean or along the coast sometimes create tsunamis.
Mount St. Helens used to be Washington’s fifth tallest peak at 9,677 feet. In 1980, it erupted and the blast was so great that it ripped off 1,300 feet of the mountaintop, making it Washington’s thirteenth tallest peak.
Volcanoes have killed about 225,000 people in the last two centuries.
On average, a major destructive eruption occurs somewhere in the world every ten years.
People who are killed by volcanoes usually die from the poisonous gases that is spewed out from the volcano and exposure to the intense blasts of heat, both of which are invisible.
Currently there are about 1,550 active volcanoes on Earth.
