Summary
Abstract:

Detailed maps bring a greater resolution to the number and locations of active

faults. Preparing maps at a higher resolution requires extensive field study,

and with a GIS, information, such as tract and parcel data, utility corridors,

and flood hazard zones, can be incorporated to help decision makers in locating

remediation facilities.


After the Sylmar ...


Active faults and strips of state-mandated zoning along faults (Alquist-Priolo

zones) riddle the Salton Sea Basin. The primary fault, the San Andreas, steps

from the northeast side of the Salton Sea across the southern end, along a

series of poorly understood faults, to the Brawley and Imperial fault systems.

This stepover region has not had a historic ground-rupturing earthquake.

Alquist-Priolo zones could not be defined because the faults are not

well-located. Faults parallel to, and splaying from, the San Andreas are also

capable of major earthquakes.


Initial plans for remediation facilities take into account the generalized

information (at 1:750,000 scale) on active faults, and the fault maps do not

provide information on strong ground shaking. The shaking can damage facilities

that lie far from an earthquake epicenter and far from active faults.

Information on near-surface materials is required to estimate the

ground-shaking hazards.
