MAGNITUDE 4.9
Noticeable shaking of indoor objects. Damage is unlikely.
The scale is logarithmic: this released about 710 times the energy of a magnitude 3.0, roughly the energy of 338 tonnes of TNT.
98.2 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
2 earthquakes above our reporting threshold within 250 km of this one, the largest a magnitude 5.1.
