History
edit
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 [2] and consists of ash plumes and, less commonly, pyroclastic flows and lava domes.[1]
The volcano erupted on 15 July 2011, forcing thousands of people to evacuate.[3]
The volcano again began showing signs of activity on 10 February 2012, and 19 September 2012 (11:01pm). An eruption occurred at 8:20, am[4] the same day sending an ash plume two miles into the sky. Local residents were evacuated from a two and a half mile exclusion zone around the volcano.[5] An eruption occurred on 17 December 2012.
Indonesia has 129 volcanoes including Mount Lokon. The eruption of Mount Lokon in 1991 killed a Swiss hiker and forced thousands of people to flee their homes.[6]
