A magnitude 6.4 earthquake struck off the east coast of Taiwan on 11 June 2025, according to the Central Weather Administration (CWA).
The tremor prompted a national alert as emergency systems were activated across the island.
The earthquake occurred at 7 p.m. local time, with its epicentre located approximately 69.9 kilometres south of Hualien County Hall.
The quake originated under the Pacific Ocean, close to Taiwan’s eastern coastline, at a focal depth of 30.9 kilometres, the CWA reported.
The seismic event registered its strongest intensity at a low level 5 on Taiwan’s intensity scale in Taitung County.
Meanwhile, areas such as Hualien, Nantou, Taichung, Changhua, Yunlin, and Chiayi County recorded intensity levels of 4.
Taiwan’s seismic intensity scale ranges from 1 to 7, measuring the strength of ground shaking felt at specific locations. A level 5 quake indicates moderate to strong shaking, potentially felt indoors and causing unsecured objects to shift or fall.
Following the tremor, there were no immediate reports of damage or casualties. However, precautionary measures were quickly implemented across public transportation systems to ensure safety.
In the Taipei metropolitan area, mass rapid transit (MRT) rail systems temporarily reduced train speeds.
Operators carried out safety checks before resuming normal operations. The Taiwan High-Speed Rail (THSR) services running between Taipei and Kaohsiung remained unaffected, maintaining their scheduled operations.
The earthquake did not result in any reported power outages or disruption to other critical infrastructure. Emergency services remained on standby to respond to any subsequent incidents or aftershocks.
