EPICENTRE
MAGNITUDE 4.6
Noticeable shaking of indoor objects. Damage is unlikely.
The scale is logarithmic: this released about 250 times the energy of a magnitude 3.0, roughly the energy of 120 tonnes of TNT.
499.4 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.
NEARBY IN THE PAST 30 DAYS
7 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 5.9.
