Outlined circle: this earthquake
In context
How big was it, and why here?
Energy released
41 kilotons of TNT
That is about 3 times the Hiroshima bomb. It released about 86 times the energy of a magnitude 5.0.
Tectonic setting
29 km
from the nearest mapped plate boundary, between the Philippine Sea and Yangtze plates. Earthquakes cluster along boundaries like this one, where plates collide, pull apart or slide past each other.
Depth: shallow
35 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.
