M4.6 earthquake near Ternate, Indonesia

A magnitude 4.6 earthquake struck 155 km (96 mi) west-southwest of Ternate, Indonesia on Sunday, October 25, 2026 at 12:09 UTC, at a depth of 44 km (27 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 778 km (484 mi) away.
Why here?
This earthquake struck about 350 km (217 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 4.6 released roughly the energy of 120 tons of TNT. That is about 7.9 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 22,000,000 times more than this one.
Aftershocks
In the first 22 hours 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 200 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
- M7.7 · 148 km SE of Tondano, IndonesiaMay 14, 1932
- M7.7 · 264 km ESE of Luwuk, IndonesiaNovember 29, 1998
- M7.7 · 121 km E of Bitung, IndonesiaAugust 10, 1968
