MAGNITUDE 4.8

Noticeable shaking of indoor objects. Damage is unlikely.

The scale is logarithmic: this released about 500 times the energy of a magnitude 3.0, roughly the energy of 239 tonnes of TNT.

554.4 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.
