122-38HaywardFault
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

California Public Utilities Commission
The California Public Utilities Commission (CPUC or PUC) is a regulatory agency that regulates privately owned public utilities in the state of California, including electric power, telecommunications, natural gas and water companies. In addition, the CPUC regulates common carriers, including household goods movers, passenger transportation companies such as limousine services, and rail crossing safety. The CPUC has headquarters in the Civic Center district of San Francisco, and field offices in Los Angeles and Sacramento. History On April 1, 1878, the California Office of the Commissioner of Transportation was created. During the 19th century, public concerns over the unbridled power of the Southern Pacific Railroad grew to the point that a three-member Railroad Commission was established, primarily to approve transportation prices. However, the Southern Pacific quickly dominated this commission to its advantage, and public outrage re-ignited. As experience with public regula ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Andreas Fault
The San Andreas Fault is a continental transform fault that extends roughly through California. It forms the tectonics, tectonic boundary between the Pacific Plate and the North American Plate, and its motion is Fault (geology)#Strike-slip faults, right-lateral strike-slip (horizontal). The fault divides into three segments, each with different characteristics and a different degree of earthquake risk. The slip rate along the fault ranges from /yr. It was formed by a transform boundary. The fault was identified in 1895 by Professor Andrew Lawson of University of California, Berkeley, UC Berkeley, who discovered the northern zone. It is often described as having been named after San Andreas Lake, a small body of water that was formed in a valley between the two plates. However, according to some of his reports from 1895 and 1908, Lawson actually named it after the surrounding San Andreas Valley. Following the 1906 San Francisco earthquake, Lawson concluded that the fault extende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hayward Fault Zone
The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. This fault is about long, situated mainly along the western base of the hills on the east side of San Francisco Bay. It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. The Hayward Fault is parallel to the San Andreas Fault, which lies offshore and through the San Francisco Peninsula. To the east of the Hayward Fault lies the Calaveras Fault. In 2007, the Hayward Fault was discovered to have merged with the Calaveras Fault east of San Jose at a depth of , with the potential of creating earthquakes much larger than previously anticipated. Some geologists have suggested that the Southern Calaveras should be renamed as the Southern Hayward. North of San Pablo Bay is the Rodgers Creek Fault, which was shown in 2016 to be linked with the Hayward Faul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foothill
Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. Frequently foothills consist of alluvial fans, coalesced alluvial fans, and dissected plateaus. Description Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain, but can also border uplands and higher hills. Examples Areas where foothills exist, or areas commonly referred to as the foothills, include the: *Sierra Nevada foothills of California, USA *Foothills of the San Gabriel Valley in Los Angeles County, California, USA *Rocky Mountain Foothills in British Columbia and Alberta, Canada *Silesian Foothills in Silesia, Poland *Sivalik Hills along the Himalayas in the Indian subcontinent * Catalina ...

Santa Cruz Mountains
The Santa Cruz Mountains, part of the Pacific Coast Ranges, are a mountain range in central and Northern California, United States. They form a ridge down the San Francisco Peninsula, south of San Francisco. They separate the Pacific Ocean from the San Francisco Bay and the Santa Clara Valley, and continue south to the Central Coast, bordering Monterey Bay and ending at the Salinas Valley. The range passes through the counties of San Mateo, Santa Clara, Santa Cruz, San Benito and Monterey, with the Pajaro River forming the southern boundary. Geography The northernmost portion of the Santa Cruz Mountains, north of Half Moon Bay Road ( SR 92), is known as Montara Mountain; the middle portion is the Sierra Morena, which includes a summit called Sierra Morena, and extends south to a gap at Lexington Reservoir; south of the gap, the mountain range is known as the Sierra Azul. The highest point in the range is Loma Prieta Peak, west of Morgan Hill, with a height of , near the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Range Geomorphic Province
The Coast Range Geomorphic Province is a portion of coastal California, United States. This orogen geomorphic province constitutes a barrier between the Pacific Ocean and the San Joaquin Valley which trends northwest from Point Conception to the border with Oregon, with a significant break in the San Francisco Bay Area by the basins of the Sacramento River and San Joaquin River that discharge into the Pacific. The province consists of mountain ranges and the corresponding valleys and basins. The San Francisco Bay Area naturally subdivides the province into the North Coast Ranges and South Coast Ranges. The province is formed as an interaction between the North American and Pacific tectonic plates. The Pacific Plate moves northwest relatively to the North American one with speed of about 35–38 mm/year, with the majority of motion occurring during large earthquakes, with some aseismic fault creep. The overlap of the plates is about 100 km wide and contains all major ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
