A magnitude 7.1 earthquake — a major event — struck near 180 km NNE of Gili Air, Indonesia on August 28, 2023, at a deep-focus depth of about 500 km. An earthquake this size would have been felt strongly across the surrounding region; deep-focus earthquakes rarely cause major surface damage despite their size. A tsunami threat was flagged for this event — large, shallow quakes beneath or near the ocean can lift the seafloor and generate destructive waves. 629 people submitted "Did You Feel It?" shaking reports to the USGS.
