What this magnitude typically means
Very small earthquakes are usually only detected by instruments and are rarely felt. They are a normal part of background seismic activity. 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.
