The Clayton-Marsh Creek-Greenville Fault is a fault located in the eastern San Francisco Bay Area of California, in Alameda County and Contra Costa County. It is part of the somewhat parallel system of faults that are secondary to the San Andreas Fault.
The 5.8 magnitude 1980 Livermore earthquake occurred on this fault. [1] The fault creeps at a rate of at 2 mm/year. [2] The predicted probability of a major earthquake on this fault within the next 30 years is relatively low, at 3%, compared to nearby faults such as the Hayward Fault.
The Gorda plate, located beneath the Pacific Ocean off the coast of northern California, is one of the northern remnants of the Farallon plate. It is sometimes referred to as simply the southernmost portion of the neighboring Juan de Fuca plate, another Farallon remnant.
The Livermore Valley AVA is an American Viticultural Area in Alameda County, California, surrounding the city of Livermore in the Tri-Valley region. It is named after the Livermore Valley, which is named, along with the city, after Robert Livermore, a landowner whose holdings encompassed the valley.
Murray Township was a township located in what is now the Livermore Valley portion of Alameda County, California, including the present day cities of Livermore, Dublin, and Pleasanton, and the census-designated place of Sunol.
Founded in 1891, Livermore Union High School is a public high school located in the city of Livermore, California, United States. It is part of the Livermore Valley Joint Unified School District. In 2007, it was chosen as one in four schools in Alameda County to receive the California Distinguished School award.
The Calaveras Fault is a major branch of the San Andreas Fault System that is located in northern California in the San Francisco Bay Area. Activity on the different segments of the fault includes moderate and large earthquakes as well as aseismic creep. The last large event was the magnitude 6.2 1984 Morgan Hill event. The most recent moderate earthquakes were the magnitude 5.1 event on 25 October 2022, and the magnitude 5.6 2007 Alum Rock event.
The Mocho Subbasin is the largest of the groundwater subbasins in the watershed of the Livermore Valley in Northern California. This subbasin is bounded to the west by the Livermore Fault Zone and to the east by the Tesla Fault. Some groundwater flow occurs across these fault boundaries, but flows are discontinuous below a depth of fifty feet across the Tesla Fault and south of the Arroyo Mocho channel across the Livermore Fault. Surface watercourses in this unit include Arroyo Valle and Arroyo Seco.
The Tesla Fault can be found in the northeastern Diablo Range, California. This fault is only semi-active.
The Bernal Subbasin is an aquifer located in the southwestern corner of Livermore Valley Groundwater Basin, Alameda County, California, United States. All of the groundwater in Livermore Valley moves toward the Bernal Subbasin, which is bounded on the east by Pleasanton Fault, on the north by the Park Fault, and on the west by the Calaveras Fault.(Earth Metrics, 1989) All the streams draining the Livermore Valley merge above the Bernal formation and exit this subbasin and Livermore Amador Valley via the Arroyo de la Laguna.
The Niles Cone is a groundwater basin in Alameda County, California, United States which is the source of drinking water for a sizeable human urban population in the East Bay. The land area corresponding to this groundwater basin is approximately 103 square miles; the Niles Cone Basin is bounded on the east by the Diablo Range and on the west by San Francisco Bay. Surface runoff in the Alameda Creek catchment basin accounts for much of the recharge of the Niles Cone. The Alameda County Water District is responsible for management of the Niles Cone aquifer and has developed water treatment plants and pipelines for the conveyance of its waters to urban users. The Alameda County Water District also performs water quality monitoring of the Niles Cone Basin for total dissolved solids and other parameters.
The Livermore Valley, historically known as the Valle de San José, is a valley in Alameda County, California, located in the East Bay region. The city of Livermore is located in the valley. The valley became known as "Livermore's Valley", and today as the "Livermore Valley" after Robert Livermore, an early settler and rancher in the region who received together with José Noriega a land grant composing most of modern Livermore.
The San Jacinto Fault Zone (SJFZ) is a major strike-slip fault zone that runs through San Bernardino, Riverside, San Diego, and Imperial Counties in Southern California. The SJFZ is a component of the larger San Andreas transform system and is considered to be the most seismically active fault zone in the area. Together they relieve the majority of the stress between the Pacific and North American tectonic plates.
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.
Laddville is a former settlement in the western Livermore Valley of Alameda County, California.
Ulmar is a former unincorporated community now annexed to Livermore in Alameda County, California. It lies at an elevation of 551 feet. This former siding has median estimated value of $777,110 and expected growth rate of 2.40% for 2017-2022 according to that survey.
The Hosgri Fault is an offshore fault zone located near the Central Coast of California in San Luis Obispo County. The main fault stretches for about 87 miles (140 km), and is located nearest to the coastal communities of Cambria, San Simeon, Morro Bay, Baywood Park-Los Osos and Avila Beach. The fault system is some 260 mi (420 km) long, and is a right-lateral strand of the San Andreas Fault system.
The Mount Diablo Thrust Fault, also known as the Mount Diablo Blind Thrust, is a thrust fault in the vicinity of Mount Diablo in Contra Costa County, California. The fault lies between the Calaveras Fault, the Greenville Fault, and the Concord Fault, all right-lateral strike-slip faults, and appears to transfer movement from the Calaveras and Greenville Faults to the Concord Fault, while continuing to uplift Mount Diablo.
The 1927 Lompoc earthquake occurred on November 4 at 05:49 PST with an epicenter off the coast of Santa Barbara County Southern California. The earthquake measured 7.0 on the moment magnitude scale and had a maximum Modified Mercalli intensity of IX (Violent). It caused widespread damage in several towns of Santa Barbara County. A 2 m tsunami damaged railroad infrastructure and was recorded in Hawaii. There were no injuries or deaths from the earthquake.
Naval Air Station Livermore has nearby airfield landing strips to support the training of US Navy pilots during World War 2. The airfield are called Naval Outlying Landing Field (NOLFs). For the war many new trained pilots were needed. The Naval Outlying Landing Fields provided a place for pilots to practice landing and take off without other air traffic. The remotes sites offered flight training without distractions. Most of the new pilots departed to the Pacific War after training. The Outlying Landing Fields had little or no support facilities. Naval Air Station Livermore opened in 1942 and closed in 1951. The Outlying field closed in 1945, having completed the role of training over 4000 new pilots. To open the needed Outlying Landing Fields quickly, the Navy took over local crop dusting and barnstorming airfields.
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.
The 1980 Livermore earthquake occurred on January 24 at 11:00 PST in California. The epicenter of the 5.8 Mw earthquake was a hilly area 12 km (7.5 mi) southeast of Mount Diablo and north of Livermore Valley. The earthquake had a maximum Modified Mercalli intensity of VII. Forty four people were injured and damage across the San Francisco Bay Area totaled $11.5 million, with the majority inflicted at the Lawrence Livermore National Laboratory.
