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.

10 KM DEEP

Shallow earthquakes release their energy close to the surface, so they are felt more strongly, and do more damage, than deeper earthquakes of the same magnitude.

NEARBY IN THE PAST 30 DAYS

1 earthquake above our reporting threshold within 250 km of this one, the largest a magnitude 4.5.
