Felt by 21 people across nearby locations.
On March 12, 2026 at 12:14 UTC, a magnitude 5.1 shallow crustal earthquake struck 28 km S of Hualien City, Taiwan, at a depth of 30.3 km and coordinates 23.7234°, 121.5932°. This earthquake was detected by 97 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 410, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
