In context
How big was it, and why here?
Energy released
4 tons of TNT
That is about 1/3,975 of the Hiroshima bomb. A magnitude 5.0 releases about 126 times more energy.
Tectonic setting
167 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.

After the main event
Aftershocks within 50 km
USGS lists 27 M2.5+ earthquakes within 50 km in the following 30 days; the largest was M4.3 on September 14, 1995. Most nearby activity right after a large earthquake is aftershocks, which usually become less frequent over days and weeks.
