A magnitude-6.6 earthquake occurred in waters near Yilan County in China's Taiwan region on December 27, 2025, according to the China Earthquake Networks Center (CENC). The quake struck at 60 km depth, with tremors felt across multiple urban centers.
Immediate Infrastructure Effects
Security camera footage from Taipei showed prolonged building vibrations during the midday event, while sections of ceiling paneling collapsed at Taoyuan International Airport's Terminal 2. Airport authorities temporarily closed affected areas for safety inspections, though flight operations continued with minor delays.
Regional Seismic Context
This marks the strongest seismic event in the Taiwan Strait region since April 2024. The CENC has deployed technical teams to monitor aftershocks, with three tremors below magnitude 4.0 recorded within six hours of the main quake. No casualties or major structural collapses have been reported as of press time.
Local authorities have activated emergency response protocols, with particular attention to coastal areas vulnerable to potential secondary effects. Mainland Chinese seismological institutions have offered technical support through existing cross-strait communication channels.
