In context

How big was it, and why here?

Energy released

1 kilotons of TNT

That is about 1/15 of the Hiroshima bomb. It released about 2 times the energy of a magnitude 5.0.

Tectonic setting

498 km

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

Depth: shallow

15 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.
