In context
How big was it, and why here?
Energy released
11 kilotons of TNT
That is about the energy of the Hiroshima bomb. It released about 24 times the energy of a magnitude 5.0.
Tectonic setting
68 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 1 M2.5+ earthquake within 75 km in the following 30 days; the largest was M5.5 on March 21, 1926. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
