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.
This is a source-linked archive. Source measurements and assessments can change. An archived bulletin is not evidence that a warning is currently active.
