M5.0 Earthquake 69 km S of Hualien City, Taiwan — March 22, 2022
2022-03-22 18:37:49 UTC (2022-03-22) · approx. 2:37 AM UTC+8 local
On March 22, 2022 at 18:37 UTC, a magnitude 5.0 shallow crustal earthquake struck 69 km S of Hualien City, Taiwan, at a depth of 26.4 km and coordinates 23.3464°, 121.6155°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
