Map: the earthquake near Lajamina, Panama, with plate boundaries

A magnitude 4.5 earthquake struck 7 km (4 mi) east-northeast of Lajamina, Panama on Monday, October 12, 2026 at 02:22 UTC, at a depth of 10 km (6 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 Panama City, Panama, about 162 km (101 mi) away.

Why here?

This earthquake struck about 54 km (34 mi) from the boundary between the Cocos 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 4.5 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 14 days after it, USGS recorded 9 smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi). The largest was a magnitude 4.4 on October 13 at 05:28 UTC.

A stronger magnitude 4.7 followed on October 14 at 05:09 UTC, about 59 km (37 mi) away, so this one is now considered a foreshock.

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

Before this earthquake, USGS had recorded 72 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
