Indonesia’s Mt. Lokon Erupts Hurling Ash Cloud into the Sky

A restless volcano in northern Indonesia erupted Friday, spewing clouds of ash as high as 2 kilometers into the sky, the country’s National Disaster Management Agency said.

The authorities are warning residents to stay away from the volcano, Mt. Lokon, in North Sulawesi, said Sutopo Purwo Nugroho, a spokesman for the disaster management agency.

A 2.5 kilometer exclusion zone had already been set up around Mt. Lokon, which had been showing signs of activity in recent days.

A series of eruptions by Mt. Lokon in July prompted the evacuation of thousands of local residents. The volcano also erupted in October and December.

Indonesia is located on the “Ring of Fire,” an arc of fault lines circling the Pacific Basin that is prone to frequent earthquakes and volcanic eruptions.

Mount Lokon, together with Mount Empung, is a twin volcano (2.2 km/1.4 mi apart) in the northern Sulawesi, Indonesia, roughly 10 km (6 mi) south of Manado. Both rise above the Tondano plain and are among active volcanoes of Sulawesi. Mount Lokon has a flat and craterless top.

Lokon formed during a period of andesitic volcanism on ring fractures resulting from the Tondano caldera’s early to mid-Pleistocene collapse. Recently-erupted material remains andesitic in composition and consists of ash plumes and, less commonly, pyroclastic flows and lava domes.
