Map: the earthquake near Yilan, Taiwan, with plate boundaries

A magnitude 4.5 earthquake struck 64 km (40 mi) southeast of Yilan, Taiwan on Monday, November 2, 2026 at 02:23 UTC, at a depth of 55 km (34 mi), according to the U.S. Geological Survey.

Why here?

This earthquake struck about 61 km (38 mi) from the boundary between the Eurasian and Okinawa plates. Most earthquakes happen along plate boundaries like this one, where the pieces of Earth’s outer shell collide, pull apart or grind past each other. Stress builds up over years until the rock suddenly slips.

The red lines on the map are plate boundaries.

How strong was it?

Magnitude is logarithmic: each whole step releases about 32 times more energy. This magnitude 4.5 released roughly the energy of 85 tons of TNT. That is about 5.6 times the energy of a magnitude 4.0, a quake people nearby feel but that rarely causes damage. The strongest earthquake ever recorded, magnitude 9.5 in Chile in 1960, released about 32,000,000 times more than this one.

Aftershocks

In the first 1 hour after it, USGS recorded no smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi).

Outside the United States, USGS mainly lists quakes of about magnitude 4 and up, so smaller aftershocks there are undercounted.

Earthquake history here

Before this earthquake, USGS had recorded 287 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
