What this magnitude typically means
Moderate earthquakes are widely felt and can cause light damage close to the epicenter. The shaking you actually experience depends on how far away you are and what kind of ground you are on. 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.
