Urban Seismic Hazard Maps
These new types
of maps and derivative products build on the National Seismic Hazard Maps,
but also include the amplifying and damping effects of the local geology,
soils, and sediments on ground shaking at a resolution appropriate for urban
and emergency response planning.

Probabilistic hazard maps showing ground
motions (peak ground accelerations) with a 2% probability
of being exceeded in 50 years. Inset map
of Memphis, Shelby County includes the effects of sediments, superimposed
on the larger national seismic hazard map that does not.
