1997 Punitaqui Earthquake
The 1997 Punitaqui earthquake occurred at 01:03 UTC on October 15. It had an estimated magnitude of 7.1 . This earthquake was one of the most destructive in the epicentral area compared to other events of subduction of the same size. The extensive damage to structures was the result of an amplification effect on the ground and the poor quality of building materials, this reflects the potential for damage incurred in an intraplate earthquake with vertical fault and how it can be much greater than what which can cause one of interplate of similar magnitude, and caused severe damage in Chilean cities of La Serena, Vicuña, Ovalle, Illapel and Punitaqui.''Chile tiembla otra vez'', El Mercurio, November 18, 2007, page D10 Tectonic setting Chile lies above the convergent plate boundary where the Nazca Plate is subducting beneath the South American Plate, at a location where they converge at a rate of seventy millimeters a year. This quake was an oceanic interplate type, occurred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telecommunication
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumb ...

Regions Of Chile
Chile is divided into 16 regions (in Spanish, ''regiones''; singular ''región''), which are the country's first-level administrative division. Each region is headed by an intendant (''intendente)'', appointed by the President of Chile, and a directly elected regional board (''consejo regional''). The regions are divided into provinces (the second-level administrative division), each headed by a governor (''gobernador'') appointed by the President. There are 56 provinces in total. Provinces are divided into communes (the third and lowest level administrative division), which are governed by municipal councils. Naming Each region was given a Roman numeral, followed by a name (e.g. ''IV Región de Coquimbo'', read as "fourth region of Coquimbo" in Spanish). When the regional structure was created, Roman numerals were assigned in ascending order from north to south, with the northernmost region designated as I (first) and the southernmost region as XII (twelfth).

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 ...

Araucanía Region
The Araucanía ( ), La Araucanía Region ( es, Región de La Araucanía ) is one of Chile's 16 first-order administrative divisions, and comprises two provinces: Malleco in the north and Cautín in the south. Its capital and largest city is Temuco; other important cities include Angol and Villarrica. Chile did not incorporate the lands of the Araucanía Region until the 1880s, when it occupied the area to end resistance by the indigenous Mapuche by both military and political means. This opened up the area for Chilean and European immigration and settlement. In the 1900–1930 period, the population of Araucanía grew considerably, as did the economy despite recessions striking the rest of Chile. Araucanía became one of the principal agricultural districts of Chile, gaining the nickname of "granary of Chile". The administrative Araucanía Region was established in 1974, in what was the core of the larger historic region of Araucanía. In the 21st century, Araucanía is Ch ...
