Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

674 kg of TNT

That is about 1/22,353 of the Hiroshima bomb. A magnitude 5.0 releases about 708 times more energy.

Tectonic setting

455 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

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.

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.
