TAIPEI (Taiwan News) — A magnitude 5.7 earthquake struck Tainan’s Nanxi District on Sunday at 7:38 a.m., with a shallow depth of 8.1 km, according to the Central Weather Administration (CWA).

The quake’s effects were felt across the country, with neighboring areas such as Chiayi County, Kaohsiung City, Chiayi City, Yunlin County, and Changhua County experiencing magnitude 4 tremors on the Richter Scale, per CNA.

The CWA warned of potential aftershocks or additional seismic activity, including earthquakes of magnitude 5 or higher in the coming week. It urged the public to remain prepared but not to panic.

According to the CWA, the earthquake resulted from the Philippine Sea Plate moving northward and colliding with the Eurasian Plate off the coast of Hualien.

A key area of concern was the Tsengwen Reservoir, located near the epicenter. The Water Resources Agency conducted an inspection and found no damage, citing the reservoir’s high earthquake resistance coefficient. The solid rock of the surrounding mountainous areas adds an extra layer of safety, the agency said.

Despite the magnitude 4 tremors reported in neighboring counties, the CWA noted the earthquake was relatively brief, lasting only one to two seconds. As a result, residents in tall buildings as far away as Taipei were the only ones likely to feel the quake.
