The Elsinore Fault Zone is a large geologic fault structure in Southern California. In Geology a fault, or fault line, is a planar rock fracture which shows evidence of relative movement California ( is a US state on the West Coast of the United States, along the Pacific Ocean.
The Elsinore fault zone runs from the mountainous region between El Centro and San Diego, northwest to Chino Hills. Chino Hills is a suburb located in the southwestern corner of San Bernardino County, California, United States On the southern end of the fault zone is the southeastern extension of the Elsinore fault zone, the Laguna Salada Fault. At its northern end, the Elsinore fault zone splits into two segments, the Chino Fault and the Whittier Fault. The Whittier Fault is a Geologic fault that is a branch of the Elsinore Fault Zone in Southern California.
The Elsinore fault zone, not including Whittier, Chino, and Laguna Salada faults, is 180 kilometers (111 miles) long. Its slip rate is 4. 0 millimeters/year (0. 15 in/yr). It is estimated that this zone is capable of producing a quake of MW6. 5 - 7. 5 on the moment magnitude scale. TalkMoment magnitude scale#Real world examples please.--> The moment magnitude scale The projected interval between major rupture events is 250 years.
The main fault zone is one of the quietest in California, producing only one quake above a magnitude of 5. 2 in known history, an estimated magnitude 6 on the Richter Scale in 1910 but the quake did little damage and produced no surface rupturing. The Richter magnitude scale, or more correctly local magnitude M L scale assigns a single number to quantify the amount of seismic energy released
