In context
How big was it, and why here?
Energy released
477 kg of TNT
That is about 1/31,575 of the Hiroshima bomb. A magnitude 5.0 releases about 1,000 times more energy.
Tectonic setting
294 km
from the nearest mapped plate boundary, between the Philippine Sea and Sunda plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.
Depth: intermediate
96 km
Intermediate-depth earthquakes usually break inside a plate that is sinking into the mantle. Shaking spreads over a wide area but is gentler at the epicenter than a shallow quake of the same size.
After the main event
Aftershocks within 50 km
USGS and EMSC list 10 M2.5+ earthquakes within 50 km since this event; the largest was M4.1 on September 12, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
