In context

How big was it, and why here?

Energy released

30 kilotons of TNT

That is about 2 times the Hiroshima bomb. It released about 63 times the energy of a magnitude 5.0.

Tectonic setting

1 km

from the nearest mapped plate boundary, between the Arabian and African plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.

Depth: shallow

13 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.

USGS publishes PAGER impact estimates for significant earthquakes, usually within an hour. No PAGER estimate is available for this event.

After the main event

Aftershocks within 100 km

USGS lists 7 M2.5+ earthquakes within 100 km in the following 30 days; the largest was M6.1 on April 5, 1969. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
