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.

103.7 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

3 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 5.1.
