M4.7 Earthquake 19 km SE of Yilan, Taiwan — February 24, 2026
2026-02-24 04:37:15 UTC (2026-02-24) · approx. 12:37 PM UTC+8 local
Felt by 13 people across nearby locations. Aftershock of the M5.8 mainshock.
On February 24, 2026 at 04:37 UTC, a magnitude 4.7 intermediate depth earthquake struck 19 km SE of Yilan, Taiwan, at a depth of 72.8 km and coordinates 24.6474°, 121.9039°. This earthquake was detected by 142 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 345, 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.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.8 mainshock that occurred 18 days ago 29 km ENE of Yilan, Taiwan. Since the mainshock, the USGS has recorded 0 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 4.7 earthquake near Yilan, Taiwan?
The magnitude 4.7 earthquake that struck 19 km SE of Yilan, Taiwan on February 24, 2026 at 04:37 UTC had a depth of 72.8 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?
The earthquake epicenter was located at 24.6474°, 121.9039°, which is 19 km SE of Yilan, Taiwan. View all earthquakes in Taiwan.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.8 one earlier?
No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 5.8 mainshock that occurred earlier 29 km ENE of Yilan, 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 4.7 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
