2023-08-21 10:01:18 UTC (2023-08-21) · approx. 6:01 PM UTC+8 local
On August 21, 2023 at 10:01 UTC, a magnitude 5.2 deep-focus earthquake struck near Flores Sea, at a depth of 515.4 km and coordinates -7.4132°, 120.4887°. This earthquake was detected by 141 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
