Isluga

Stratovulcano · Chile · 5550 m

The flanks of Isluga volcano in Chile are formed by numerous lobate lava flows visible in this June 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 23 km across). The lavas have lateral levees and pressure ridges especially visible on the southern flanks. The most recent 400-m-diameter summit crater is visible at the western side of the summit area.

Sintesi geologica

The broad Isluga volcano lies 7 km W of the Chile/Bolivia border at the W end of a group of volcanoes extending to Tata Sabaya volcano in Bolivia. A stratovolcano, it contains a well-preserved, 400-m-wide summit crater at the W end of the elongated, snow-covered summit region. Numerous postglacial lava flows, many showing distinct levees, are most prominent along a broad front on the lower S flank. Activity from the summit crater was reported in the 19th and 20th centuries. A lava flow in 1878 destroyed several towns.
