M5.2 Earthquake 29 km NNE of Hualien City, Taiwan — April 26, 2024
2024-04-26 18:49:29 UTC (2024-04-26) · approx. 2:49 AM UTC+8 local
Felt by 26 people across nearby locations. Maximum shaking intensity MMI 4.2 (moderate).
On April 26, 2024 at 18:49 UTC, a magnitude 5.2 shallow crustal earthquake struck 29 km NNE of Hualien City, Taiwan, at a depth of 40.5 km and coordinates 24.2394°, 121.6724°. The earthquake was reported felt by 26 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.2 (moderate). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 252 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 430, placing it among routine seismic activity. The nearest populated place is Yilan (population 94,188).
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.
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 5.2 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 5.2 event is significantly smaller than that historical record.
