What the map is telling you
Magnitude, depth and location answer different questions. None of them alone predicts the shaking at your address.
Data and methodology →Depth
The estimated origin below the surface. Shallow events often produce stronger local shaking at similar magnitude.
Distance
Local pages calculate distance from a stated center. The epicenter may be offshore or outside a city boundary.
