Magnitude is not shaking

Magnitude describes the earthquake’s size. The shaking experienced at a place depends on distance, depth, local ground conditions and the rupture.

Depth needs context

A reported depth describes the location of the earthquake underground. Some solutions use an assigned depth; uncertainty and review status matter.

Nearby does not mean aftershock

Our regional search finds events by distance and time. Establishing an aftershock sequence requires seismological assessment.
