In context

How big was it, and why here?

Energy released

2 tons of TNT

That is about 1/7,931 of the Hiroshima bomb. A magnitude 5.0 releases about 251 times more energy.

Tectonic setting

52 km

from the nearest mapped plate boundary, between the Philippine Sea and Sunda plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.

Depth: shallow

50 km

Shallow earthquakes (under 70 km) produce the strongest surface shaking for their size, so they are the ones most likely to cause damage near the epicenter.

After the main event

Aftershocks within 50 km

USGS and EMSC list 1 M2.5+ earthquake within 50 km since this event; the largest was M3.9 on September 25, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
