Indonesia, Simeulue: 2005-2018

The Simeulue cluster is named for the island of Simeulue off the north coast of Sumatra, Indonesia. The cluster is based on 33 events recorded by a temporary network of OBS's from October 2005 to February 2006 to record aftershocks of the Mw 8.6 earthquake of March 28, 2005 (Nias-Simeulue), which was itself probably triggered by the great Sumatra earthquake of December 26, 2004 (Mw 9.1). The Nias-Simeulue earthquake is included in the cluster. Readings from the OBS network (kindly provided by Frederick Tilmann, GFZ Potsdam) provide the calibration of the cluster, which was expanded with moderate-sized events since 2006 to improve the set of teleseismic arrival time data. Many events in the cluster have good datasets of teleseismic [...]
