The 1943 Alahan Panjang earthquakes occurred on June 8 and June 9 UTC (June 9, 1943, local time) in Sumatra, then under Japanese occupation. This was an earthquake doublet (the shocks occurred at the same location on consecutive days).[5]
Map of the Great Sumatran Fault with labelled segments
The first mainshock occurred on June 8 at 20:42 UTC. It ruptured the Suliti segment of the Sumatran Fault Zone. The magnitude was given as Mw 7.2,[1] or Ms 7.1.[6]
The second mainshock occurred on June 9 at 03:06 UTC. It ruptured the Sumani segment of the Sumatran Fault Zone and perhaps the northwestern part of the Suliti segment. The magnitude was given as Mw 7.5,[1] or Ms 7.4.[6]
Alahan Panjang was damaged in the earthquakes.[5] Right lateral offsets were reported near the town of Solok.[6]
Near the Sumani segment, earthquake doublets occurred repeatedly.[7] Similar earthquake doublet nearby include the earthquakes in 1926 and 2007.[8]
