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.
