M4.5 Earthquake near South Indian Ocean — June 18, 2022
2022-06-18 20:06:26 UTC (2022-06-18) · approx. 3:06 AM UTC+7 local
On June 18, 2022 at 20:06 UTC, a magnitude 4.5 shallow crustal earthquake struck near South Indian Ocean, at a depth of 10.0 km and coordinates -12.5833°, 102.9501°. This earthquake was detected by 20 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
