Kentur Lokon, Stratovolcano in Tomohon City, Indonesia

Kentur Lokon is a stratovolcano near Tomohon that rises 1,580 meters above the Tondano plain. The mountain features two main peaks with a flat summit area between them, where the active Tompaluan crater lies.

The volcano has been active since 1375 with several documented eruptions. A major event in 1991 resulted in the death of a Swiss hiker and caused local evacuations.

In the local Minahasan language the name Lokon means "the eldest" or "the old one," also rendered Tua Lokon or Tou Tua Lokon, "old person." A giant footprint is said to be found on the mountain's slopes. The active crater, Tompaluan, sits on the volcano's foot rather than at the flat, craterless summit.

The hiking trail begins from Tomohon at about 800 meters elevation and follows a path along an old lava flow to the crater. The route takes around three hours, so starting early and checking local conditions beforehand is wise.

Lokon's active crater, Tompaluan, sits on the mountain's lower flank rather than at the flat, craterless summit. The 1991 eruption destroyed the roofs of thousands of homes in Kakaskasen, Kinilow and Tinoor under 15 to 20 cm of ash and debris, and a Swiss hiker, Vivian Clavel, disappeared, presumed buried by a cold lahar.
