On September 17, 2022 at 14:35 UTC, a magnitude 5.1 shallow crustal earthquake struck 80 km E of Yujing, Taiwan, at a depth of 10.0 km and coordinates 23.0859°, 121.2505°. This earthquake was detected by 67 seismic stations with good location accuracy and was assigned a USGS significance rating of 403, 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.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.

Has Taiwan had earthquakes this big before?

The largest recorded earthquake in Taiwan was the M7.6 Chi-Chi earthquake of September 21, 1999. Today's magnitude 5.1 event is significantly smaller than that historical record.
