2026-01-25 10:49:42 UTC (2026-01-25) · approx. 6:49 PM UTC+8 local
On January 25, 2026 at 10:49 UTC, a magnitude 4.7 shallow crustal earthquake struck 58 km SE of Hengchun, Taiwan, at a depth of 10.0 km and coordinates 21.6411°, 121.1497°. This earthquake was detected by 65 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
