Details for: Lastarria
The elongated NNW-trending edifice of 5697-m-high Lastarria volcano rises above pyroclastic-flow deposits that form an extensive apron below the northern flanks of the volcano. Five nested craters are found along a semi-arcuate line on the summit ridge. The youngest feature is a lava dome that overlaps the northern crater rim. Persistent fumarolic activity occurs at the summit and NW flank, and small sulfur flows 350 m long have been produced by melting of extensive sulfur deposits in the summit region.

Description: 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. 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.
