Earthquakes in Taiwan
Taiwan is one of the most seismically active islands in the world, experiencing approximately 2,000 earthquakes per year. The Philippine Sea Plate collides with the Eurasian Plate beneath Taiwan at 7-8 cm per year, building the island's mountain ranges and generating frequent large earthquakes. The 1999 Chi-Chi earthquake (M7.6) and the 2024 Hualien earthquake (M7.4) demonstrated the severe hazard facing Taiwan's 23 million residents.

View on live map →Why Taiwan Has Frequent Earthquakes
Taiwan sits at the convergence of the Philippine Sea and Eurasian plates, creating one of the world's most tectonically active regions. The island is bisected by numerous active thrust faults on its western side and east coast. Mountain building is occurring in real time — GPS measurements show the island growing westward at several centimeters per year.

FAQ
Frequently Asked Questions
Common questions about earthquakes in Taiwan.
How often does Taiwan experience major earthquakes?
Taiwan experiences an M6.0+ earthquake roughly every few months and an M7.0+ event approximately every decade. The island has one of the world's highest rates of large earthquakes per unit area.
What was the 1999 Chi-Chi earthquake?
The September 21, 1999 Chi-Chi earthquake (M7.6) is Taiwan's deadliest in modern history, killing 2,415 people and injuring over 11,000. It ruptured 100 km of the Chelungpu Fault with surface displacement up to 9 meters. The event triggered a comprehensive overhaul of Taiwan's seismic building codes.
What was the 2024 Hualien earthquake?
The April 3, 2024 Hualien earthquake (M7.4) was the strongest to strike Taiwan since 1999. It caused severe building damage in Hualien city, including the partial collapse of several structures, and killed 18 people. Tsunami warnings were issued for Japan and the Philippines.
Why is Taiwan so earthquake-prone?
Taiwan sits at the convergence of the Philippine Sea and Eurasian tectonic plates, which collide at 7-8 cm per year. The island is bisected by numerous active thrust and strike-slip faults. GPS measurements show active mountain building in real time, with the central range rising several millimeters per year.
What should I do during an earthquake in Taiwan?
Taiwan's earthquake early warning system (EEW) delivers alerts via mobile phone seconds before shaking arrives. During shaking, drop and take cover under a table or desk. After the shaking stops, check for gas leaks before re-entering buildings. Follow the Central Weather Administration (CWA) for aftershock updates.
