2023-08-05 18:33:59 UTC (2023-08-05) · approx. 2:33 AM UTC+8 local
Felt by 62 people across nearby locations. Maximum shaking intensity MMI 7.1 (severe).
On August 5, 2023 at 18:33 UTC, a magnitude 5.4 shallow crustal earthquake struck 24 km S of Dezhou, China, at a depth of 18.0 km and coordinates 37.2306°, 116.3908°. The earthquake was reported felt by 62 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.1 (severe). The USGS PAGER system issued a red alert level for this event, indicating widespread severe impact likely. This earthquake was detected by 199 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 2056, making it one of the most significant global earthquakes in recent days. The nearest populated place is Lingcheng (population 0).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
