Tectonic Summary

  The November 21, 2022, M 5.6 Indonesia earthquake occurred at shallow depth as a result of strike slip faulting within the crust of the Sunda plate. Focal mechanisms indicate that the rupture occurred on either a steeply dipping north-striking, right-lateral strike-slip fault, or a steeply dipping east-striking left-lateral strike-slip fault. About 260 km southwest of this event, the Australia plate moves north-northeast at about 59 mm/yr with respect to the Sunda plate, subducting at the Sunda Trench.

   This region of the plate boundary between the Australia and Sunda plates is highly seismically active. Past strong earthquakes have occurred within each of the Australia and Sunda plates, as well as on the plate interface. Since 2007, there have been four earthquakes of M 6.5 or larger events within 250 km of the November 21, 2022, earthquake. The largest of these events was a M 7.5 on August 8, 2007, which occurred at a depth of about 280 km within the subducted Australia plate.
