  1. Relationship between the Santa Sonica, Hollywood, and Raymond faults. BY DIEGO FURTADO

  2. COMPRESSION ZONE • The “BIG BEND”: Cause of • Compression between the Pacific • Plate and North American Plate • Mountains and faults are formed: • San Gabriel Mountains and • Santa Monica Mountains • Transverse Range Southern • Boundary Fault System: Extends • from east to west unlike other • California mountains

  3. TRANSVERSE RANGES FAULT SYSTEM • Base of San Gabriel and Santa Monica Mountains • West- trending system of faults that extends for 200 km • Oblique-slip, reverse-slip, and strike-slip

  4. RAYMOND, SANTA MONICA, AND HOLLYWOOD FAULTS SANTA MONICA HOLLYWOOD RAYMOND ▼ ▼ ▼ TYPE OF FAULT : Left-reverse Left-reverse Left-lateral (minor reverse) LAST KNOWN SURFACE RUPTURE: ~900 A.D ~800 A.D. ~1000 A.D PROBABLE MAGNITUDES: 6.0 - 7.0 5.8 – 6.5 6.0 – 7.0 SLIP RATE (mm/yr): 0.27 – 0.39 0.33 – 0.75 0.10 - 0.22 LENGTH: 40 km 15 km 26 km • Santa Monica fault connects with Hollywood • fault at west Beverly Hills Lineament • Hollywood fault likely connects to Raymond • fault at Los Angeles River floodplain
