EARTHQUAKEM5.1

M5.1 earthquake in the Banda Sea

Map: the earthquake in the Banda Sea, with plate boundaries

A magnitude 5.1 earthquake struck in the Banda Sea on Monday, November 2, 2026 at 00:53 UTC, at a depth of 94 km (58 mi), according to the U.S. Geological Survey. At this intermediate depth, shaking spreads out before it reaches the surface. The epicenter was about 405 km (252 mi) southeast of Ambon. The nearest city of a million or more people is Makassar, about 1,180 km (733 mi) away.

Why here?

This earthquake struck about 211 km (131 mi) from the boundary between the Australian and Timor 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. At 94 km down, it most likely broke inside a plate that is sinking into the mantle beneath its neighbor, in what geologists call a subduction zone.

How strong was it?

Magnitude is logarithmic: each whole step releases about 32 times more energy. This magnitude 5.1 released roughly the energy of 674 tons of TNT. That is about 45 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 4,000,000 times more than this one.
