Broken Top in the Three Sisters Wilderness, Oregon, is, as the name suggests, the heavily eroded top of a probably extinct stratovolcano.

Background:

The earliest products were basaltic lava flows forming a basal shield. Later stage eruptions built a steeper cone of more silica rich lava flows and pyroclastic deposits.

Hot Spots
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
Kuril Islands
Photos from the Kuril Islands: Some rarely visited volcanoes, unspoiled nature, lots of WWII remnants - browse through several galleries from our tours to the Kuril Islands.
Books
Books about volcanoes: A selection of recommended books about volcanoes and volcanism.
Kamchatka
