Coatepeque Caldera

Coatepeque Caldera (Nawat: kuātepēk, "at the snake hill") is a volcanic caldera in El Salvador in Central America. The caldera was formed during a series of rhyolitic explosive eruptions from a group of stratovolcanoes between about 72,000 and 57,000 years ago. Since then, basaltic cinder cones and

lava flows formed near the west edge of the caldera, and six rhyodacitic lava domes have formed. The youngest dome, Cerro Pacho, formed after 8000 BC.
