Map: the earthquake near Coquimbo, Chile, with plate boundaries

A magnitude 4.7 earthquake struck 94 km (58 mi) north-northwest of Coquimbo, Chile on Wednesday, October 14, 2026 at 00:30 UTC, at a depth of 22 km (14 mi), according to the U.S. Geological Survey. Shallow quakes like this one shake the surface hardest. The nearest city of a million or more people is Santiago, Chile, about 484 km (301 mi) away.

Why here?

This earthquake struck about 69 km (43 mi) from the boundary between the South American and Nazca 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 4.7 released roughly the energy of 169 tons of TNT. That is about 11 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 16,000,000 times more than this one.

Aftershocks

In the first 12 days after it, USGS recorded 3 smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi). The largest was a magnitude 4.6 on October 14 at 00:36 UTC.

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 134 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
