Los Angeles Region Basin Depth Map

 

Two important local geologic factors that affect the level of shaking experienced in earthquakes are (1) the softness of the surface rocks and (2) the thickness of surface sediments. This image of the Los Angeles region shows the depth of sedimentary basins.

 

A basin depth calculator can be used to determine this thickness under specific areas of southern California.
