What this magnitude typically means
Minor earthquakes are often felt close to the epicenter but almost never cause damage. Whether you feel one at all depends on how near and how shallow it is. 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.
