What this magnitude typically means
Light earthquakes are felt by most people nearby but rarely cause damage. Distance, depth, and soil type determine whether a quake feels sharp or barely noticeable. Tremor does not compute a single local shaking figure here, because how strong a quake feels at any address depends on distance, depth and local geology — open the interactive globe to explore the ShakeMap and estimated intensity.
