Sekincau volcano and the Belirang and Balak caldera – South Sumatra

 

Sekincau volcano was constructed near the southern rim of the small NW-SE-trending double Belirang and Balak calderas, 2 and 2.5 km wide, respectively. The 300-m-wide crater of Sekincau is open to the south. The age of the latest eruptive activity is not known, although fumarolic activity occurs on the caldera floor and on the E and SE outer flanks of Balak caldera.
