Isluga

Stratovolcano · Chile · 5550m

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.

Geological summary

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.
