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).〔http://www.jeofizikci.org/Makale/SumatranFault.pdf〕 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,〔 or Ms 7.1. 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,〔 or Ms 7.4. Alahan Panjang was damaged in the earthquakes. Right lateral offsets were reported near the town of Solok. Near the Sumani segment, earthquake doublets occurred repeatedly.〔"Source model of an earthquake doublet that occurred in a pull-apart basin along the Sumatran fault, Indonesia" by M. Nakano, H. Kumagai, S. Toda, R. Ando, T. Yamashina, H. Inoue, Sunarjo.〕 Similar earthquake doublet nearby include the earthquakes in 1926 and 2007.〔http://www.jsce.or.jp/report/45/files/singkarak_earthquake_jsce2007.pdf〕 == See also == *List of earthquakes in 1943 *List of earthquakes in Indonesia 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「1943 Alahan Panjang earthquakes」の詳細全文を読む スポンサード リンク
