In context
How big was it, and why here?
Energy released
951 kg of TNT
That is about 1/15,825 of the Hiroshima bomb. A magnitude 5.0 releases about 501 times more energy.
Tectonic setting
240 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: shallow
18 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 17 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.
