In addition to southern Sumatra, the earthquake could be felt in western Java and Singapore.[1] Intense smoke and gas activity was observed in the Suwoh volcanic area.[4]
The earthquake took place at the Sumatran Fault Zone. The Sumatran Fault Zone is 1900 km long and highly segmented. It can be divided into about 20 segments.[2] The earthquake occurred in a subparallel strand 2.5 km southwest of the principal trace of the Kumering segment.[3][6] The focal mechanism is of right-lateral strike-slip faulting.[4]
