In context

How big was it, and why here?

Energy released

15 kg of TNT

That is about 1/998,483 of the Hiroshima bomb. A magnitude 5.0 releases about 31,623 times more energy.

Tectonic setting

702 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

1 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 7 M2.5+ earthquakes within 50 km since this event; the largest was M2.9 on September 21, 2026. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
