Map: the earthquake near Bitung, Indonesia, with plate boundaries

A magnitude 5.2 earthquake struck 117 km (73 mi) southeast of Bitung, Indonesia on Friday, October 9, 2026 at 05:11 UTC, at a depth of 40 km (25 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 Davao, Philippines, about 707 km (439 mi) away.

Why here?

This earthquake struck about 358 km (222 mi) from the nearest major plate boundary, which makes it an intraplate earthquake. These happen on old faults inside a plate, where stress from the plate’s slow movement is released. They are less common, but can surprise areas that rarely feel quakes.

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 5.2 released roughly the energy of 951 tons of TNT. That is about 63 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 2,800,000 times more than this one.

Aftershocks

In the first 17 days after it, USGS recorded 5 smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi). The largest was a magnitude 5.1 on October 10 at 02:00 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 205 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
