An avalanche is a slide of a large snow (or rock) mass down a mountainside, caused when a buildup of snow is released down a slope, and is one of the major dangers faced in the mountains in winter. An avalanche is an example of a gravity current consisting of granular material. In an avalanche, lots of material or mixtures of different types of material fall or slide rapidly under the force of gravity. Avalanches are often classified by what they are made of, for example snow, ice, rock or soil avalanches. A mixt ...

Avalanche breakdown is a current multiplication process that occurs only in strong electric fields, which can be caused either by the presence of very high voltages, such as in electrical transmission systems, or by more moderate voltages which occur over very short distances, such as within semiconductor devices. The electric field strength necessary to achieve avalanche breakdown varies greatly between different materials: in air, 3 MV/m is typical, while in a good insulator such as some ceramics, fields in excess of 40 MV/m can be needed. ...

Even small avalanches are a serious danger to life, even with properly trained and equipped companions who avoid the avalanche. Between 55 and 65 percent of victims buried in the open are killed, and only 80 percent of the victims remaining on the surface survive. (McClung, p.177). Thus, one normally would have a 20% chance of survival if caught in a significant avalanche. Research carried out in Italy (Nature vol 368 p21) based on 422 buried skiers indicates how the chances of survival drop: very rapidly from 92% ...

A disaster (from Latin meaning, "bad star") is the impact of a natural or man-made event that negatively affects life, property, livelihood or industry often resulting in permanent changes to human societies, ecosystems and environment. (It may be noted that event itself is not a disaster, it is the impact which is called disaster.) Disasters manifest as hazards exacerbating vulnerable conditions and exceeding individuals' and communities' means to survive and thrive. Most events included herein are compiled from United States Federal Emergency Management Age ...

Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes. Since it is composed of small rough particles it is a granular material. It has an open and therefore soft structure, unless packed by external pressure. Snow is commonly formed when water vapor undergoes deposition high in the atmosphere at a temperature of less than 0°C (32°F), and then falls to the ground. Snow - Types. Flurries A period of light snow with usually little accumulati ...

Wellington, later known as Tye, was a small railroad community on the Great Northern Railway in northeastern King County, Washington. Founded in 1893, it was located at the west portal of the original Cascade Tunnel under Stevens Pass. It is infamous for being the site of the March 1, 1910, Wellington avalanche, the worst avalanche in United States history, in which 96 people died. After the disaster, the town's name was changed to Tye, after the nearby Tye River, because of the negative connotation of the original name. Tye was ab ...

The Vancouver Island Marmot (Marmota vancouverensis) is found only in the high mountainous regions of Vancouver Island, in British Columbia, Canada. The species can be distinguished from other marmots by their rich, chocolate brown fur and contrasting white patches. Individuals live in small colonies in subalpine meadows on steep, avalanche-prone slopes, preferring those with a southern exposure. They usually hibernate 8 months out of the year. These animals ar ...

In cryptography, a cryptographic hash function is a hash function with certain additional security properties to make it suitable for use as a primitive in various information security applications, such as authentication and message integrity. A hash function takes a long string (or message) of any length as input and produces a fixed length string as output, sometimes termed a message digest or a digital fingerprint. In various standards and applications, the two most-commonly used hash functions are MD5 and SHA ...

Vertical Limit (2000) is an action movie/thriller directed by Martin Campbell (GoldenEye, No Escape) starring, among others, Chris O'Donnell, Robin Tunney and Scott Glenn. It narrates the attempted ascent of K2 by a group of alpinists, led by an ambitious multi-millionaire. But the climbing party get into serious jeopardy after an avalanche goes down, kills some of the members and traps others inside a crevasse. At the base, a rescue team is formed to rediscover their buried mates. The undertaking soon becomes a r ...

The group started out as a punk outfit, featuring Robbie Chater, Darren Seltmann, Gordon McQuilten and Toni Diblasi. This eventually evolved into hip hop, and by the time the group hit the Melbourne scene in 1997, there was a huge degree of hype surrounding them - with the band supporting Jon Spencer Blues Explosion after less than a half a dozen shows. They also supported the Beastie Boys on the Australian l ...

Avalanche diode - Protection. A common application is protecting electronic circuits against damaging high voltages. The avalanche diode is connected to the circuit so that it is reverse-biased. In other words, its cathode is positive with respect to its anode. In this configuration, the diode is non-conducting and does not interfere with the circuit. If the voltage increases beyond the design limit, the diode suffers avalanche breakdown, causing the harmful voltage to be conducted to earth. When used in this fas ...

The Avalanche was launched in 2001 as a 2002 model on the GMT800 platform. First year Avalanches featured light gray plastic body cladding. This provided needed visual distinction from the Suburban. The Avalanche also gave the public an advance look at the next generation of front fascia designs for the entire GM line of trucks. A full-length chrome strip splits each lamp assembly and the grille, with a gold Chevrolet "bow tie" in the center. The hood and fenders featured aggressive folds, in contrast ...

A plasma begins with a rare natural 'background' ionization event of a neutral air molecule, perhaps as the result of photoexcitation or background radiation. If this event occurs in an area with a high potential gradient, the positive ion will be strongly attracted toward, or repelled away from, an electrode (depending on the polarity of the corona), whereas the electron will be attracted in the opposite direction. When an electron avalanche occures between two electrodes and is of sufficient siz ...

Avalanche is a mutant with the superhuman ability to generate powerful waves of vibrations from his hands, creating highly destructive effects. The vibrations can cause an inorganic object to shatter or crumble into dust. When directed against large objects like buildings or upon the earth itself, the vibrations can produce effects similar to those of an earthquake or avalanches within limited areas. Avalanche need not touch an object to affect it: he can direct t ...

A Natural phenomenon can easily cause a natural disaster. Appearing to arise without direct human involvement, natural disasters are sometimes called an act of God. A natural disaster may become more severe because of human actions prior, during or after the disaster itself. A specific disaster may spawn different types of events and may reduce the survivability of the initial event. A classic example, is an earthquake that collapses homes, trapping people and breaking gas mains that then ignite, and burn people alive while trapped under deb ...

When the Québec Nordiques found themselves experiencing on-ice success but off-ice financial failure during the lockout shortened 1994-95 NHL season team owner Marcel Aubut asked for a bailout from Quebec's provincial government. The bailout fell through and Aubut subsequently sold the team to a group of investors in Denver. The franchise moved to Colorado and was renamed the Colorado Avalanche. Colorado entered their first season in Denver with a very strong lineup that included such excellent players as captain Joe ...

The noise is due to the multiplication process at a multiplication, M is denoted by by F(M) and is given by kM + (1 − k)(2 − 1 / M). k is the ratio of the impact ionization rates of the two signs of charge carriers. For an electron multiplication device it is given by the hole impact ionization rate divided by the electron impact ionization rate. It is desirable to have a large asymmetry between these rates, in order to minimize See also:
