Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
15 kg of TNT
That is about 1/998,483 of the Hiroshima bomb. A magnitude 5.0 releases about 31,623 times more energy.
Tectonic setting
1 km
from the nearest mapped plate boundary, between the Aegean Sea and Eurasian plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.
Depth: shallow
11 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 and EMSC have not published any M2.5+ earthquake within 50 km since this event.
