Overview

Klabat is a symmetrical stratovolcano near the tip of the northern arm of Sulawesi Island, east of the city of Manado. There is a shallow lake in the 170 x 250 m summit crater. No verified reported eruptions are known, but there has been fumarolic activity.

A reported eruption in 1683 CE was probably from Tangkoko, 19 km NE.

About the Photo

Klabat, seen here from the city of Manado to its west, is an isolated symmetrical stratovolcano that rises to 1995 m near the eastern tip of the northern arm of Sulawesi. It has a shallow lake in its 170 x 250 m summit crater. No verified historical eruptions have occurred from this volcano, the highest in Sulawesi.
