Lokon

 

Lokon-Empung is an active twin volcano in North Sulawesi, Indonesia, formed by two peaks, Lokon and Empung. Lokon is the more active peak, with a distinctive flat top and an active crater, Tompaluan, located on its flank. This crater is a deep explosion pit situated between the two peaks. The volcano’s activity is fueled by the subduction of tectonic plates in the region, leading to the formation of andesitic magma. Eruptions typically involve ash plumes, pyroclastic flows, and occasional lava dome growth.

Location: North Sulawesi, Indonesia
