EPICENTRE
MAGNITUDE 5.5
Can damage poorly constructed buildings; well-built structures usually escape with little harm.
The scale is logarithmic: this released about 180 times the energy of a magnitude 4.0, roughly the energy of 3 thousand tonnes of TNT.
531.5 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
6 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 4.5.
