MAGNITUDE 6.5

Can be destructive in populated areas up to about 160 km across.

The scale is logarithmic: this released about 180 times the energy of a magnitude 5.0, roughly the energy of 85 thousand tonnes of TNT.

492.4 KM DEEP

Deep earthquakes rarely cause damage. The energy dissipates over hundreds of kilometres before reaching the surface, though it can still be felt far from the epicentre.
