The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Lastarria is a stratovolcano on the Argentina/Chile border. The volcano contains 5 nested summit craters. The youngest part of the volcano is a lava dome overlapping the northern crater.
A large prehistoric debris avalanche deposit is located on the SE flank and younger deposits of pyroclastic flows form an apron around the the northern base of the volcano.
There are no known historical eruptions, but the young morphology of some deposits suggest that Lastarria has been active during historical time. There is intense fumarolic activity on the rim and flanks of the northern summit crater and its NW flank, and sulfur flows have occurred by melting of extensive sulfur deposits in the summit region.
