A magnitude number means little on its own; what matters is how hard the ground shakes where you are, and that depends on distance and depth as much as size. Drop an epicenter, set the magnitude, and see the intensity fan out — who feels a rumble, and who watches the walls come down.
Drop, cover, hold on — then check gas, water and structure. Knowing your shaking risk shapes how you build and store.
The magnitude isn't the story — the shaking is.

This is a generalized intensity model from magnitude, distance and depth. Real shaking varies a lot with local soil (soft ground amplifies) and fault type — treat it as the broad pattern, not a site prediction.
