Ventura Fault
Ventura Fault also Ventura-Pitas Point Fault is an offshore and onshore fault system of Southern California, beginning around Santa Barbara coming onshore in Ventura with an eastward heading, its extension is unknown but presumed to head for San Bernardino. It is among a network of faults in the area, potentially connecting to San Cayetano Fault, Lion Fault, and Red Mountain Fault (the latter offshore). Tsunami potential California Geological Survey researchers have reported that the fault is capable of an 8.0 earthquake, along with tsunami A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

USGS – Ventura Fault ☺
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredth anniversa ...

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 ...

Ventura, California
Ventura, officially named San Buenaventura (Spanish for "Saint Bonaventure"), is a city on the Southern Coast of California and the county seat of Ventura County. The population was 110,763 at the 2020 census. Ventura is a popular tourist destination, owing to its historic landmarks, beaches, and resorts. Ventura was founded by the Spanish in 1782, when Saint Junípero Serra established Mission San Buenaventura. Following the Mexican secularization of the Californian missions, San Buenaventura was granted by Governor Pío Pico to Don José de Arnaz as Rancho Ex-Mission San Buenaventura and a small community arose. Following the American Conquest of California, San Buenaventura eventually incorporated as a city in 1866. The 1920s brought a major oil boom, which along with the post–World War II economic expansion, significantly developed and expanded Ventura. History Archaeological discoveries in the area suggest that humans have populated the region for at least 10,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

San Cayetano Fault
The San Cayetano Fault is an east-west trending thrust fault in Ventura County, Southern California. It stretches for , north of the city of Ventura, near the Topatopa Mountains, Piru, Fillmore, Santa Paula, Sulphur Springs, and Ojai. Geology The last known surface rupture was less than 5,000 years ago. Recent research indicates that the San Cayetano fault may have been the source of the December 21, 1812 earthquake. Depending on location, the fault has an estimated slip rate between . The recurrence rate between events is uncertain, but if the fault is associated with the 1812 event, it may be able to produce earthquakes approaching 6.5 – 7.3 in magnitude.

California Geological Survey
The California Geological Survey, previously known as the California Division of Mines and Geology, is the California state geology, geologic agency. History Although it was not until 1880 that the California State Mining Bureau, predecessor to the California Geological Survey, was established, the "roots" of California's state geological survey date to an earlier time. As might be expected for a state that owed its existence to the California Gold Rush, gold rush of 1849, the California State Legislature recognized that geologists could provide valuable information. In 1851, one year after California was admitted to the United States, the Legislature named John B. Trask, a medical practitioner and active member of the California Academy of Sciences, as Honorary State Geologist. In 1853 the Legislature passed a joint resolution asking him for geological information about the state. He submitted a report ''On the Geology of the Sierra Nevada (U.S.), Sierra Nevada, or California Ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give ...

Seismic Faults Of California
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Geology Of Ventura County, California
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Ear ...
