2008 Reno Earthquakes
The Reno earthquakes of 2008, also known as the "Mogul-Somersett earthquake sequence", occurred in or near the western Reno, Nevada, suburbs of Mogul and Somersett. The earthquake swarm began in February 2008, but the first significant quake of the series occurred on April 15, 2008, registering a 3.6 magnitude. On April 24, 2008, two quakes in the same area registered 4.1 and 4.2. On April 25, 2008, the quake of largest magnitude occurred, registering 4.7 on the Richter scale and causing damage in the immediate area around the epicenter, including destroying of a wooden flume supplying water from the Highland Ditch, also known as the Highland Ditch flume. The flume carried up to a day from the Highland Ditch to Reno's Chalk Bluff Water Treatment Facility and another to area irrigation users. In addition to these significant quakes, hundreds of smaller events have also occurred in the same area. This swarm is significant because no known dominant fault line has been responsible ...

Reno, Nevada
Reno ( ) is a city in the northwest section of the U.S. state of Nevada, along the Nevada-California border, about north from Lake Tahoe, known as "The Biggest Little City in the World". Known for its casino and tourism industry, Reno is the county seat and largest city of Washoe County and sits in the High Eastern Sierra foothills, in the Truckee River valley, on the eastern side of the Sierra Nevada. The Reno metro area (along with the neighboring city Sparks) occupies a valley colloquially known as the Truckee Meadows which because of large-scale investments from Greater Seattle and San Francisco Bay Area companies such as Amazon, Tesla, Panasonic, Microsoft, Apple, and Google has become a new major technology center in the United States. The city is named after Civil War Union Major General Jesse L. Reno, who was killed in action during the American Civil War at the Battle of South Mountain, on Fox's Gap. Reno is part of the Reno–Sparks metropolitan area, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquake Swarm
In seismology, an earthquake swarm is a sequence of seismic events occurring in a local area within a relatively short period. The time span used to define a swarm varies, but may be days, months, or years. Such an energy release is different from the situation when a major earthquake (main shock) is followed by a series of aftershocks: in earthquake swarms, no single earthquake in the sequence is obviously the main shock. In particular, a cluster of aftershocks occurring after a mainshock ''is not'' a swarm. History and generalities In the Ore Mountains (Erzgebirge), which form the border between the Czech Republic and Germany, western Bohemia and the Vogtland region, have been known since the 16th century as prone to frequent earthquake swarms, which typically last a few weeks to a few months. Austrian geologist Josef Knett, while studying in 1899 a swarm of about a hundred events felt in western Bohemia/Vogtland in January-February 1824, coined the noun ''Schwarmbeben'', ' ...

Richter Magnitude Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Epicenter
The epicenter, epicentre () or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

Fault Line
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 ...

1915 Pleasant Valley Earthquake
The 1915 Pleasant Valley earthquake occurred at in north-central Nevada. With a moment magnitude of 6.8, a surface wave magnitude of 7.7, and a maximum Mercalli intensity of X (''Extreme''), it was the strongest earthquake ever recorded in the state. Earthquake The earthquake remains as one of the best examples ever for evidence of creating fault scarps along the west side of the Tobin Range. It produced four scarps, with a total length of , and re-ruptured Holocene scarps located at the bottom of the base of the mountain blocks. Among the scarps, the average vertical displacement among the affected areas was , and the maximum displacement of occurred near the old Pierce School site on Buskee Creek Canyon.Mt. Tobin, Nev 15 minute topographic quadrangle, 1961, USGS The rupture originated along an unnamed fault somewhere in the eastern side of Pleasant Valley, in north-central Nevada. The epicentral region was mostly uninhabited, so there was little property damage considering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winnemucca, Nevada
Winnemucca () is the only incorporated city in, and is the county seat of, Humboldt County, Nevada, United States. As of the 2010 census, the city had a total population of 8,431, up 14.0 percent from the 2010 census figure of 7,396. Interstate 80 passes through the city, where it meets U.S. Route 95. History and culture The town was named for the 19th-century Chief Winnemucca of the local Northern Paiute tribe, who traditionally lived in this area. Winnemucca, loosely translated, means "one moccasin." The chief's daughter, Sarah Winnemucca, was an advocate for education and fair treatment of the Paiute and Shoshone tribes in the area. Their family all learned to speak English, and Sarah worked as an interpreter, scout and messenger for the United States Army during the Bannock War of 1878. In 1883, Sarah Winnemucca published the first autobiography written by a Native American woman, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
