What this magnitude typically means
A magnitude in this range can cause significant damage near the epicenter, especially to vulnerable buildings. How strongly any given place shakes still depends on distance, depth, and ground conditions. 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.
