Lake Elsinore is a natural freshwater lake in Riverside County, California, located east of the Santa Ana Mountains and fed by the San Jacinto River. Originally named Laguna Grande by Spanish explorers, it was renamed for the town of Elsinore, established on its northeastern shore on April 9, 1888.
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.
The Temecula Valley is a graben rift valley in western Riverside County, California.
The Upper Rhine Plain, Rhine Rift Valley or Upper Rhine Graben is a major rift, about 350-kilometre-long (220 mi) and on average 50-kilometre-wide (31 mi), between Basel in the south and the cities of Frankfurt/Wiesbaden in the north. Its southern section straddles the France–Germany border. It forms part of the European Cenozoic Rift System, which extends across Central Europe. The Upper Rhine Graben formed during the Oligocene, as a response to the evolution of the Alps to the south. It remains active to the present day. Today, the Rhine Rift Valley forms a downfaulted trough through which the river Rhine flows.
The Chino Fault extends along the eastern Chino Hills range region, from Corona in Riverside County to the Los Serranos, Chino Hills area of San Bernardino County in Southern California.
The Coyote Mountains are a small mountain range in San Diego and Imperial Counties in southern California. The Coyotes form a narrow ESE trending 2 mi (3.2 km) wide range with a length of about 12 mi (19 km). The southeast end turns and forms a 2 mi (3.2 km) north trending "hook". The highest point is Carrizo Mountain on the northeast end with an elevation of 2,408 feet (734 m). Mine Peak at the northwest end of the range has an elevation of 1,850 ft (560 m). Coyote Wash along I-8 along the southeast margin of the range is 100 to 300 feet in elevation. Plaster City lies in the Yuha Desert about 5.5 mi (8.9 km) east of the east end of the range.
Temescal Creek is an approximately 29-mile-long (47 km) watercourse in Riverside County, in the U.S. state of California. Flowing primarily in a northwestern direction, it connects Lake Elsinore with the Santa Ana River. It drains the eastern slopes of the Santa Ana Mountains on its left and on its right the western slopes of the Temescal Mountains along its length. With a drainage basin of about 1,000 square miles (2,600 km2), it is the largest tributary of the Santa Ana River, hydrologically connecting the 720-square-mile (1,900 km2) San Jacinto River and Lake Elsinore watersheds to the rest of the Santa Ana watershed. However, flowing through an arid rain shadow zone of the Santa Ana Mountains, and with diversion of ground water for human use, the creek today is ephemeral for most of its length, except for runoff from housing developments and agricultural return flows.
The Imperial Fault Zone is a system of geological faults located in Imperial County in the Southern California region, and adjacent Baja California state in Mexico. It cuts across the border between the United States and Mexico.
The Pechanga Band of Indians is a federally recognized tribe of Luiseño Indians based in Riverside County, California, where their reservation is located. As of 2006, there were 1,370 members of the nation. The tribe owns the Pechanga Resort & Casino in Temecula and the naming rights to the San Diego sports arena now known as the Pechanga Arena.
The Elsinore Trough is a graben rift valley in Riverside County, southern California. It is created by the Elsinore Fault Zone.
Temescal Mountains, also known as the Sierra Temescal, are one of the northernmost mountain ranges of the Peninsular Ranges in western Riverside County, in Southern California in the United States. They extend for approximately 25 mi (40 km) southeast of the Santa Ana River east of the Elsinore Fault Zone to the Temecula Basin and form the western edge of the Perris Block.
Temescal Valley 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.
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 Clevelin Hills are a range of hills in the Peninsular Ranges System, within the Temescal Mountains in western Riverside County, in southern California.
The Perris Block is the central block of three major fault-bounded blocks of the northern part of the Peninsular Ranges. The Perris Block lies between the Santa Ana Block to the west and the San Jacinto Block to the east. The Perris Block, was named by Walter A. English in 1925 for the city of Perris, located near the center of the block.
Temecula Basin is a sedimentary basin, which, along with the Aguanga Basin, is part of the Elsinore Fault Zone, in southwestern Riverside County, California. The Temecula Basin is a basin of down faulted Mesozoic basement rock, overlain by late Cenozoic continental sediments.
Warm Springs Valley is a valley located within the city of Lake Elsinore in Riverside County, California. It lies between the main body of the Temescal Mountains to the north, east and south and the Clevelin Hills to the west. The valley was named for the warm springs that used to be found flowing there.
Pauba Valley is a valley along the course of Temecula Creek, in Riverside County, California.
The 1968 Borrego Mountain earthquake occurred on April 8, at 18:28 PST, near the unincorporated community of Ocotillo Wells in San Diego County. The moment magnitude (Mw ) 6.6 strike-slip earthquake struck with a focal depth of 11.1 km (6.9 mi). Damage was relatively moderate, and the mainshock was assigned a maximum Modified Mercalli intensity (MMI) of VII. Shaking was felt in Nevada, and Arizona. It was the largest earthquake to strike California since 1952, and its display of afterslip became the subject of scientific interest.
The San Felipe Fault Zone is an active Quaternary fault zone made up of continuous right-lateral fault strands]. It is a part of the San Andreas fault system and it is located in the western Salton Trough spanning three counties: Imperial, Riverside, and San Diego county, California. It is hypothesized to have originated during the early Pleistocene period.
