Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

338 kg of TNT

That is about 1/44,601 of the Hiroshima bomb. A magnitude 5.0 releases about 1,413 times more energy.

Tectonic setting

166 km

from the nearest mapped plate boundary, between the Somali and African plates. Earthquakes this far from a boundary happen on faults inside a plate, often less frequently but sometimes strongly.

Depth: shallow

10 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.
