Mt. St. Helens: Back From the Dead
Learn the Science
INVESTIGATE A VOLCANO'S DESTRUCTION
Since 1700, volcanic eruptions have killed more than 250,000 people. They can devastate communities and landscapes, wipe out life, and cause other natural disasters. Help your students examine the destruction caused by volcanoes.
Mt. St. Helens: Back From the Dead (Video)
See how life is bouncing back to Mt. St. Helens after it was obliterated in the eruption of 1980. (Chapter 5, approx. 7 min.)


Deadly Volcanoes (Slideshow)
Find out about some of the worst volcanic disasters of the past four centuries.


Blasts From the Past (Interactive)
Explore a map of supereruptions around the world.


A Supersized Volcano (Interactive)
See a portrait of the eruption at Toba 74,000 years ago, and how it dwarfs even the most disastrous "regular-sized" eruptions of our own era.
