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.
94.1 KM DEEP
At this depth the energy spreads before it reaches the surface. Shaking is usually weaker than a shallow earthquake of the same size, but it can be felt across a wider area.
NEARBY IN THE PAST 30 DAYS
7 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 5.4.
