Sorikmarapi

Stratovolkan · Indonesia · 2145 m

Sorikmarapi, seen here from the west, is a forested stratovolcano with a 600-m-wide summit crater containing a crater lake and substantial sulfur deposits. Another crater lake is located on the upper SE flank and several small craters occur within the main crater and on the outer flanks. Small explosive eruptions have been documented from summit and flank vents in the 19th and 20th centuries.

Ringkasan geologi

Sorikmarapi is a forested stratovolcano with a 600-m-wide summit crater containing a lake and substantial sulfur deposits. A smaller upper SE flank crater (Danau Merah) also contains a crater lake; these two craters and a series of smaller explosion pits occur along a NW-SE line. Several solfatara fields are located on the E flank. Phreatic eruptions have occurred from summit and flank vents during the 19th and 20th centuries.
