Map: the earthquake near Labuan Bajo, Indonesia, with plate boundaries

A magnitude 4.9 earthquake struck 54 km (34 mi) northeast of Labuan Bajo, Indonesia on Monday, October 19, 2026 at 09:45 UTC, at a depth of 10 km (6 mi), according to the U.S. Geological Survey.

Why here?

This earthquake struck about 312 km (194 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 4.9 released roughly the energy of 338 tons of TNT. That is about 22 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 7,900,000 times more than this one.

Aftershocks

In the first 7 days after it, USGS recorded 2 smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi). The largest was a magnitude 4.8 on October 19 at 12:06 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 68 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
