M5.2 Earthquake 60 km NE of Hengchun, Taiwan — November 13, 2022
2022-11-13 01:47:45 UTC (2022-11-13) · approx. 9:47 AM UTC+8 local
Felt by 2 people across nearby locations. Aftershock of the M5.5 mainshock.
On November 13, 2022 at 01:47 UTC, a magnitude 5.2 shallow crustal earthquake struck 60 km NE of Hengchun, Taiwan, at a depth of 12.6 km and coordinates 22.3921°, 121.1618°. This earthquake was detected by 72 seismic stations with good location accuracy and was assigned a USGS significance rating of 417, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.5 mainshock that occurred 12 days ago 108 km NE of Hengchun, Taiwan. Since the mainshock, the USGS has recorded 1 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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.

Common Questions
How strong was the magnitude 5.2 earthquake near Hengchun, Taiwan?
The magnitude 5.2 earthquake that struck 60 km NE of Hengchun, Taiwan on November 13, 2022 at 01:47 UTC had a depth of 12.6 km. For context, this was a moderate earthquake that could be widely felt.
Where did the earthquake occur?
The earthquake epicenter was located at 22.3921°, 121.1618°, which is 60 km NE of Hengchun, Taiwan. View all earthquakes in Taiwan.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.2 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.5 one earlier?
No. This magnitude 5.2 earthquake is an aftershock of the larger magnitude 5.5 mainshock that occurred earlier 108 km NE of Hengchun, Taiwan. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 5.2 event is significantly smaller than that historical record.
