The Elsinore Fault Zone is a large right-lateral strike-slip geological fault structure in Southern California. The fault is part of the trilateral split of the San Andreas Fault system and is one of the largest, though quietest faults in Southern California. [1] [2] Fault characteristics

Aug 7, 2021 · The Elsinore Fault Zone is one of the largest/longest fault zones in Southern California. By comparison to other fault in the region, the Elsinore Fault gives the impression of being a relatively quiet fault in historic times. The first known significant earthquake attributed to the Elsinore Fault in historic times occurred on 15 May, 1910 ...

The southeastern extension of the Elsinore fault zone, the Laguna Salada fault, ruptured in 1892 in a magnitude 7 quake, but the main trace of the Elsinore fault zone has only seen one historical event greater than magnitude 5.2 -- the earthquake of 1910, a magnitude 6 shock near Temescal Valley, which produced no known surface rupture and did ...

Jul 15, 2020 · Geomorphic Expression: Landscape Features Associated With Strike-Slip Fault Zones Below are examples of landscape features associated with faults that display strike-slip offset (Figure 7 and 8). A fault line is the trace of a fault plane intersects the ground surface or other surfaces, such as on a sea cliff, road cut, or in a …

In addition to the Elsinore fault, the seismicity patterns define a continuous fault between about 33°N and 33.5°N, 7 to 12 km east of the Elsinore fault, that corresponds to the Aguanga, Agua Tibia, and Earthquake Valley faults. This part of the fault zone is double stranded.

The southern Elsinore fault is part of this zone and occupies the boundary between Mesozoic crystalline rocks of the Peninsular Ranges and Late Cenozoic sedimentary rocks of the Salton Trough depocenter. The Fish Creek–Vallecito Basin, a recently inverted western sub-basin of the Salton Trough, contains a thick succession of Plio-Pleistocene ...

Dec 1, 1996 · The Elsinore fault is expressed as a simple trace north of Lake Elsinore but splits into two parallel active strands south of it (Magistrale and Rockwell, 1996), with the eastern Agua Tibia ...

Fault characteristics. The Elsinore Fault Zone, not including Whittier, Chino, and Laguna Salada faults, is 180 kilometers (110 mi) long with a slip-rate of 4.0 millimeters/year (0.15 in/yr). It is estimated that this zone is capable of producing a quake of 6.5–7.5 M W.The projected interval between major rupture events is 250 years.

Jan 25, 2018 · The Elsinore fault is certainly multi-stranded, but here there has been sustained seismicity west of the fault zone and west of the southern end of the Whittier fault. These earthquakes could be related to low-angle blind faults similar to …
