In context
How big was it, and why here?
Energy released
7.6 megatons of TNT
That is about 502 times the Hiroshima bomb. It released about 15,849 times the energy of a magnitude 5.0.
Tectonic setting
261 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
57 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.
Did You Feel It?
Where it was felt
Reports sent by people to USGS, grouped by place (most reports first). Intensity uses the Modified Mercalli scale (I–X): what people felt, not the magnitude.

After the main event
Aftershocks within 200 km
USGS lists 329 M2.5+ earthquakes within 200 km in the following 30 days; the largest was M6.5 on June 26, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
