Felt by 5 people across nearby locations.
On June 10, 2023 at 05:31 UTC, a magnitude 4.9 shallow crustal earthquake struck 37 km SSE of Yujing, Taiwan, at a depth of 26.6 km and coordinates 22.8409°, 120.6558°. This earthquake was detected by 143 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 372, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Taiwan, a region characterized by the collision of the Luzon volcanic arc with the Eurasian continental margin, where the Philippine Sea Plate converges at 80 mm per year. View all earthquakes in Taiwan.
