Hollywood Fault Zone information for land owners and developers, real estate attorneys, and geologists


In November 2014, the California Geologic Survey released the final map of earthquake fault zones in the Hollywood Quadrangle. The map shows estimated traces of the Hollywood Fault running through downtown Hollywood. In the video below, Group Delta CEO Michael Reader discusses the trench investigations we conducted at four sites where the fault was thought to exist.

The map defines a new earthquake hazard zone in Hollywood that requires most new construction projects within this zone to conduct a fault rupture investigation prior to construction permits being issued. Group Delta has a team of expert geologists and paleoseismologists who have decades of experience in locating faults within Alquist-Priolo Zones. See our page on fault investigations for more details.
