In context

How big was it, and why here?

Energy released

3 kilotons of TNT

That is about 1/5 of the Hiroshima bomb. It released about 6 times the energy of a magnitude 5.0.

Tectonic setting

21 km

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

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.

After the main event

Aftershocks within 75 km

USGS lists 2 M2.5+ earthquakes within 75 km in the following 30 days; the largest was M5.7 on March 24, 1926. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
