MAGNITUDE 4.3

Noticeable shaking of indoor objects. Damage is unlikely.

The scale is logarithmic: this released about 89 times the energy of a magnitude 3.0, roughly the energy of 43 tonnes of TNT.

259.4 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

10 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 4.7.
