The Newport-Inglewood Fault zone is considered a Holocene fault in the project vicinity (Jennings, 1994). Type of Faulting: Based on fault orientation in regional tectonic setting The Long Beach earthquake of 1933 took place on March 10, with a magnitude of 6.4, causing widespread damage to buildings throughout Southern California. The Newport–Inglewood Fault is a right-lateral strike-slip fault in Southern California. 2.2. The Newport-Inglewood fault zone extends northwest from offshore Newport Beach to Inglewood (distance of forty miles) and, like the Whittier fault, has warped and faulted marine sediments into ideal oil traps. The Newport-Inglewood fault (NIF) is an active fault with a history of damaging earthquakes that cuts coastal communities in Southern California. Geology and Soils The fault extends for 47 mi (76 km) from Culver City southeast through Inglewood and other coastal communities to Newport Beach at which point the fault extends east-southeast into the Pacific Ocean where it is known as the Rose Canyon Fault. The Newport-Inglewood is a right-lateral strike-slip fault with a slip rate of about 0.02 inches per year. “The Newport-Inglewood fault appears to sit on a 30-million-year-old subduction zone, so it is surprising that it maintains a significant pathway through the crust.” One of the deadliest earthquakes along the Newport-Inglewood fault was the Long Beach earthquake, which occurred on March 10, 1933. The NW-SE trending southern California coastline between the Palos Verdes Peninsula and San Diego roughly parallels the southern part and off-shore extension of the dominantly right-lateral, strike-slip, Newport-Inglewood fault zone.

The most recent earthquake on the Newport-Inglewood Fault zone was a magnitude M6.4 that occurred on March 10, 1933, on a segment of the fault south of Huntington Beach. The Newport-Inglewood fault zone is located mostly to the northeast of the project site (Figure 1-1). The project site is located within approximately two kilometers of the Newport-Inglewood Fault Zone, the only active fault zone within or immediately adjacent to the City of Newport Beach (Safety Element, 1975). that are essentially acting more or less parallel to the main one. GPS and UAVSAR observations indicate a zone of shear that extends southward from the Big Bend of the San Andreas fault near Gorman through the San Fernando Valley towards the Newport-Inglewood fault. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization of the Los Angeles basin, but were established instead because … That means that the expectation of a 7.0 is about one in 300 years. LA is dotted with refineries, pipelines, and active oil fields. City of Yorba Linda including the San Joaquin Hills Thrust Fault, the Newport-Inglewood Fault, the San Andreas Fault, the Peralta Hills Fault and the Whittier-Elsinore Fault. The Newport-Inglewood fault line is the same type of fault as the San Andreas, which suggests the longest fault line in California could also experience these deep quakes. Hamlin (1918 #6473) associated seismicity and faulting with the zone; first mapped and named by Taber (1920 #6491) as the Inglewood-Newport-San Onofre fault; called Newport-Inglewood fault by Hoots (1931 #5921). The epicenter was offshore, southeast of Long Beach on the Newport-Inglewood Fault. The Whittier fault joins the Chino fault near Prado Dam, and they merge into the Elsinore fault zone which trends along the eastern base of the Santa Ana Mountains. Application of cone penetrometer testing (CPT) is a promising method for studying subsurface fault zones in stratified, unconsolidated sediment where trenching is not feasible. As depicted in Table 4.D‐1, the Project Site is located approximately 2.7 miles south of the Hollywood branch of the Santa Monica‐Hollywood fault system and approximately 3.0 miles northeast of the Newport‐Inglewood fault system. In order to better see these so-called micro signals, a group of researchers temporarily deployed detectors along the Newport-Inglewood fault (NIF), which … But using the most powerful seismic sensors available, a team from Caltech in Pasadena detected small earthquakes occurring along the Newport-Inglewood fault line deeper than 24 km (15 miles), all the way into the Earth’s upper mantle – representing a whole new type of earthquake.
