Tectonic Summary

The August 19, 2018, 14:56 UTC, M 6.9 earthquake near Belanting, Indonesia, occurred as the result of shallow thrust faulting on or near The Flores Back Arc Thrust. This event occurred 14 days after the August 5, 2018, M6.9 earthquake near Pulau Lombok, Indonesia which killed at least 476 people. Both events have a similar depth and mechanism.

Prior to the August 5, 2018 earthquake two weeks prior to today’s event, there had been six other events of M 6.5 or larger over the previous century. Four of these are likely to have occurred on the back arc thrust system; a M 6.5 in the Bali region to the west of Lombok in July 1976, and three events of M 6.5, M6.5, and M 6.6 in the Sumbawa region to the east of Lombok in November 2007 and November 2009. The Sumbawa earthquakes were associated with several deaths, hundreds of injuries, and hundreds of houses being destroyed. Since the August 5, 2018 earthquake there have been 10 M 5 and greater earthquakes. Four of these have had magnitudes larger than M 6, including an M 6.3 earthquake ~10 hours prior to this August 19, 14:56 UTC earthquake. Both the August 19, 2018 event, and the August 5, 2018 earthquake, were M 6.9. [USGS]
