Elsinore Valley
Elsinore Valley is a graben rift valley in western Riverside County, California, a part of the Elsinore Trough. The Elsinore Valley is a graben between the Santa Ana Block to the southwest and the Perris Block on the northeast. It is a complex graben, divided lengthwise into several smaller sections by transverse faults. The Elsinore Valley graben is bounded northeast side by the Glen Ivy longitudinal fault on the north shore of Lake Elsinore at the foot of the Clevelin Hills and similarly on the southeast by the Willard Fault that runs along the at the foot of the Santa Ana Mountains and parallel to the Elsinore Fault along the southwest shore of Lake Elsinore to Rome Hill and the Willard Fault continues on as the west side of the Temecula Valley graben and Wolf Valley graben. At the south end of Lake Elsinore the Wildomar Fault enters the lake just east of Rome Hill, running southeast on the northwest side of the Temecula Valley. The Elsinore Valley is marked in the south by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graben
In geology, a graben () is a depressed block of the crust of a planet or moon, bordered by parallel normal faults. Etymology ''Graben'' is a loan word from German, meaning 'ditch' or 'trench'. The word was first used in the geologic context by Eduard Suess in 1883. The plural form is either ''graben'' or ''grabens''. Formation A graben is a valley with a distinct escarpment on each side caused by the displacement of a block of land downward. Graben often occur side by side with horsts. Horst and graben structures indicate tensional forces and crustal stretching. Graben are produced from parallel normal faults, where the displacement of the hanging wall is downward, while that of the footwall is upward. The faults typically dip toward the center of the graben from both sides. Horsts are parallel blocks that remain between graben; the bounding faults of a horst typically dip away from the center line of the horst. Single or multiple graben can produce a rift valley.

Santa Ana Mountains
The Santa Ana Mountains are a short peninsular mountain range along the coast of Southern California in the United States. They extend for approximately southeast of the Los Angeles Basin largely along the border between Orange and Riverside counties. Geography and climate Peaks and boundaries The range starts in the north at the Whittier Fault and Santa Ana Canyon, through which the Santa Ana River flows. To the north of the canyon are the smaller Chino Hills in Los Angeles and San Bernardino counties. The northernmost summit of the Santa Anas, at , is Sierra Peak. From there, the major summits are Pleasants Peak, ; Bedford Peak, ; and Bald Peak, . The next two peaks, Modjeska, ; and Santiago, , the highest summit in the range; form Saddleback Ridge. Saddleback, located approximately 20 mi (32 km) east of Santa Ana, is visible from much of Southern California. South of Saddleback are Trabuco Peak, ; Los Pinos Peak, and Sitton Peak, . Elsinore Peak, is incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valleys Of Riverside County, California
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. For ...

Temescal Valley (California)
Temescal Valley (''Temescal'', Spanish for "sweat lodge") in California is a graben rift valley in western Riverside County, California, a part of the Elsinore Trough. The Elsinore Trough is a graben between the Santa Ana Mountain Block to the southwest and the Perris Block on the northeast. It is a complex graben, divided lengthwise into several smaller sections by transverse faults. The Temescal Valley is one of these graben, at the northern end of the trough. The Temescal Valley graben is bounded northeast side by the Lee Lake longitudinal fault and similarly on the southeast by the Glen Ivy Fault.Rene Engel, GEOLOGY AND MINERAL DEPOSITS OF THE LAKE ELSINORE QUADRANGLE CALIFORNIA, CAIIFORNIA DEPARTMENT OF NATURAL RESOURCES, BULLETIN 146, DIVISION OF MINES, SAN FRANCISCO, 1959, pp. 50-51 The middle reach of Temescal Creek flows through Temescal Valley from Lee Lake to its confluence with the Santa Ana River.

Wildomar Fault
Wildomar is a city in southwest Riverside County, California, United States. The city was incorporated on July 1, 2008. As of the 2020 census, the population was 36,875. The community has grown very quickly during the early twenty-first century; the population has more than doubled since the 2000 census, when the community was still an unincorporated census-designated place. History In the summer of 1880 when, looking down from the peak of Mt. Baldy, Franklin Heald of Pasadena first noticed Lake Elsinore, then known as ''La Laguna''. A few months later, in October, Frank Kimbal of San Diego signed an agreement with the Atchison, Topeka and Santa Fe Railroad to build a rail line past the lake from San Diego to Barstow, then known as Waterman. The next winter, Heald traveled by buggy to see La Laguna (Lake Elsinore) at the same time work commenced on the rail line from San Diego skirting the lakeshore. The new line was to be known as the California Southern Railroad. Rails and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elsinore Fault
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. Fault characteristics The Elsinore fault zone, not including Whittier, Chino, and Laguna Salada faults, is 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 MW. The projected interval between major rupture events is 250 years. The last major rupture event on the main Elsinore fault was in 1910 with a 6 MW earthquake centered just northwest of the city of Lake Elsinore. Fault segments and geography The fault runs from the mountainous Peninsular Ranges region between El Centro and San Diego, northwest to the Chino Hills range and Chino Hills. On the southern end of the fault zone is the southeastern extension of the Elsin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
