Fault-Related CO 2 Degassing, Geothermics, and Fluid Flow in Southern California Basins--Physiochemical Evidence and Modeling This type of investigation would clarify the locations of fault traces along the Newport-Inglewood zone and it would help define the surface faulting potential. Type of Fault: Right -lateral strike-slip Length: 180 km (not including the Whittier, Chino and Laguna Salada Faults) Nearest Communities: Temecula, Lake Elsinore, Julian The newly discovered earthquakes suggest that the Newport-Inglewood fault is more active than previously thought. 1-3 The Newport-Inglewood Fault Zone is an active, right-lateral fault system consisting of a series of en echelon1 fault segments and anticlinal folds that are believed to be the expression of a deep-seated fault within the basement rock (Bryant 1988; Barrows 1974; City of Huntington Beach 1995). The Newport-Inglewood trend was first recognized as a fault zone (Fig. The 1933 Long Beach earthquake took place on March 10 at 5:54 P.M. PST south of downtown Los Angeles.The epicenter was offshore, southeast of Long Beach, California, on the Newport–Inglewood Fault. Newport-Inglewood Fault. 2–4). This finding suggests the Newport-Inglewood fault is an ancient subduction zone, where two tectonic plates collided in the past, contradicting the, currently popular, scientific hypothesis that supports the existence of a low-angle thrust fault (the décollement), below the LA Basin's surface. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization of the Los Angeles basin, but were established instead because … Now unlike, say, the Whittier Fault or Newport-Inglewood Fault, which has noticeable scars in the earth, like hills, the Puente Hills Fault is a blind thrust fault with no surface scars. The Newport-Inglewood fault zone is a major tectonic structure in 5 the Los Angeles Basin and consists of a series of disconnected, northwest-trending fault 6 segments that extend from the southern edge of the Santa Monica Mountains, through Therefore, major earthquake ruptures along the Newport-Inglewood Fault are also studied in this report in order to address the earthquake hazards for the Los Angeles basin.

NUM is a six-character unique USGS identifier that defines a fault or section id. “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 Newport-Inglewood Fault Zone is marked by a series of low mesas and hills that punctuate the basin from Newport Bay to Beverly Hills. That means that the expectation of a 7.0 is about one in 300 years. The Hollywood fault system, which includes the Malibu Coast and Santa Monica, is considered by geologists to be part of the Raymond fault. Newport-Inglewood Fault runs from off the coast of Newport Beach to Culver City, and is responsible for the chain of low hills extending from Signal Hill to the Baldwin Hills. The Hollywood fault system, which includes the Malibu Coast and Santa Monica, is considered by geologists to be part of the Raymond fault. The San Andreas Fault system distributes shearing across a complex system of primarily northwest-trending faults. An estimated fifty million dollars' worth of property damage resulted, and 120 lives were lost. The bands appear to have formed in poorly lithified sandstone. The fault extends on land for 46 miles from Culver City to Newport Beach, where it runs into the Pacific Ocean. The Newport-Inglewood fault zone is located mostly to the northeast of the project site (Figure 1-1). 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 allowable choices are provided in a pull-down menu. The Newport-Inglewood Fault sits along a boundary where two chunks of Earth’s crust grind past one another.

Generally the older deformation bands are shallow, and the younger bands are steep. and determines the line type (fault trace) to be plotted. It treats all California Type B as having the same probability per year curve versus magnitude, with two differing models. That is crazy because the Newport-Inglewood Fault is 40 miles west of the present-day edge of the plate, at the San Andreas Fault system. 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. In Southern California, scientists listening to rumblings deep underground found seismic activity at deeper-than-expected levels, and it may signal new earthquake extremes, according to a new study. 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.
