Shallow M5.5 earthquake hits offshore Taiwan
A shallow earthquake measuring M5.5 was recorded at 07:00 UTC on August 25, 2026, approximately 108 km (67 miles) northeast of Hengchun, Taiwan. The earthquake struck at a depth of 14.6 km (9.1 miles), based on reviewed data from the USGS.
The coordinates place the epicenter offshore, northeast of Hengchun in the waters near southern Taiwan, at approximately 121.6°E and 22.6°N. This area is part of the seismically active region along the boundary of the Philippine Sea Plate and the Eurasian Plate.
Given its offshore location and proximity to populated southern Taiwan, potential critical infrastructure in this region could include ports, shipping lanes, and coastal roadways servicing the island.
There is no tsunami threat associated with this earthquake, based on its location and available data.
One felt report was registered for this event. The significance index is 466 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.
Taiwan is located near a complex tectonic boundary between the Philippine Sea Plate and the Eurasian Plate, making it one of the most earthquake-prone regions in East Asia. Major fault systems run onshore and offshore, leading to frequent seismic activity.
