VOLCANOES
Volcanoes often have powerful and destructive
eruptions, but they're also quite fascinating. They vary considerably in
terms of size, shape, petrologic composition, tectonic setting, and eruptive
violence. Most volcanism on Earth (above sea level) is along subduction
zones (e.g., Cascades of western North America, Aleutian Islands of Alaska,
Central America, Andes Mountains of South America, Japan, the Philippines,
Indonesia, parts of southern Europe). Other volcanoes are at hotspots
(Hawaii, Yellowstone, Iceland, Afar, etc.) or along rift valleys (formed by
tectonic divergence). See the “Eruptions” web log
for daily updates on volcanism anywhere in the world.
