The 1994 Liwa earthquake occurred on February 16 at 00:07 local time. It was located in southern Sumatra, Indonesia. The magnitude of the earthquake was put at Mw 6.9, Mw  7.0, or Ms 7.2, according to different sources.[1][2][3][4]

The earthquake caused 207 deaths and 2000 injuries. There was damage from landslides, mudslides, and fires in Lampung Province. Power outage occurred in western Lampung.[5] Six-thousand buildings were damaged or destroyed by landslides in the Liwa area. 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]
