Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
12 kilotons of TNT
That is about the energy of the Hiroshima bomb. It released about 25 times the energy of a magnitude 5.0.
Tectonic setting
4 km
from the nearest mapped plate boundary, between the Anatolian and Eurasian 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.
