Outlined circle: this earthquake

In context

How big was it, and why here?

Energy released

1 kilotons of TNT

That is about 1/12 of the Hiroshima bomb. It released about 3 times the energy of a magnitude 5.0.

Tectonic setting

216 km

from the nearest mapped plate boundary, between the Aegean Sea and Eurasian 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.
