List Of Earthquakes In 1974
This is a list of earthquakes in 1974. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Activity was once again below average with 11 events reaching magnitude 7+. The largest came in October in Peru when a magnitude 7.6 earthquake struck Lima. Other magnitude 7.0+ events shook the Caribbean, China and the southwest Pacific Islands. Two events dominated the 25,000 deaths during 1974. China was struck by a magnitude 6.8 event in May with upwards of 20,000 deaths. At the end of the year, Pakistan was struck by a modest 6.2 magnitude earthquake causing 5,300 deaths. Gabon in c ...

Aru Islands
The Aru Islands Regency ( id, Kabupaten Kepulauan Aru) is a group of about 95 low-lying islands in the Maluku Islands of eastern Indonesia. It also forms a regency of Maluku Province, with a land area of . At the 2011 Census the Regency had a population of 84,138;Biro Pusat Statistik, Jakarta, 2011. the 2020 Census produced a total of 102,237. Some sources regard the archipelago as part of Asia, while others regard it as part of Melanesia. Administration At the time of the 2010 Census, the regency was divided into seven districts (''kecamatan''), but subsequently an additional three districts have been created by the splitting of existing districts. The districts are tabulated below with their areas (in km2) and their populations at the 2010 Census and 2020 Census. The table also includes the locations of the district administrative centres, the number of villages (''desa'') in each district, and its postal code.

National Geophysical Data Center
The United States National Geophysical Data Center (NGDC) provided scientific stewardship, products and services for geophysical data describing the solid earth, marine, and solar-terrestrial environment, as well as earth observations from space. In 2015, NGDC was merged with the National Climatic Data Center (NCDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI). Location and controlling bodies The NGDC, was located in Boulder, Colorado as a part of the US Department of Commerce (USDOC), National Oceanic & Atmospheric Administration (NOAA), National Environmental Satellite, Data and Information Service (NESDIS). Data holdings NGDC's data holdings contained more than 300 digital and analog databases, some of which were very large. As technology advanced, so did the search for more efficient ways of preserving these data. This data is now maintained by the NCEI. Data contributors NGDC worked closely with contri ...

Antofagasta Region
The Antofagasta Region ( es, Región de Antofagasta, ) is one of Chile's sixteen first-order administrative divisions. The second-largest region of Chile in area, it comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá, by Atacama to the south, and to the east by Bolivia and Argentina. The region's capital is the port city of Antofagasta; another one of its important cities is Calama. The region's main economic activity is copper mining in its giant inland porphyry copper systems. Antofagasta's climate is extremely arid, albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation, except close to the Loa River and at oases such as San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows, and the coast exhibits prominent cliffs. The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpeter ...

Moment Magnitude Scale
The moment magnitude scale (MMS; denoted explicitly with or Mw, and generally implied with use of a single M for magnitude) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori. Similar to the local magnitude scale, local magnitude/Richter scale () defined by Charles Francis Richter in 1935, it uses a logarithmic scale; small earthquakes have approximately the same magnitudes on both scales. Despite the difference, news media often says "Richter scale" when referring to the moment magnitude scale. Moment magnitude () is considered the authoritative magnitude scale for ranking earthquakes by size. It is more directly related to the energy of an earthquake than other scales, and does not saturate—that is, it does not underestimate magnitudes as other scales do in certain conditions. It has become the standard scale used by seismological authorities like the U.S. Geological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Solomon Islands
The British Solomon Islands Protectorate was first declared over the southern Solomons in 1893, when Captain Gibson, R.N., of , declared the southern islands a British protectorate. Other islands were subsequently declared to form part of the Protectorate. Establishment and addition of islands After the Anglo-German Declarations about the Western Pacific Ocean, the Protectorate was first declared over the southern Solomons in 1893. The formalities in its establishment were carried out by officers of the Royal Navy, who hoisted the British flag and read Proclamations on twenty-one islands. In April 1896, Charles Morris Woodford was appointed as an Acting Deputy Commissioner of the British Western Pacific Territories. From 30 May to 10 August 1896, HMS ''Pylades'' toured through the Solomon Islands archipelago with Woodford, who had been sent to survey the islands and to report on the economic feasibility of the British Solomon Islands Protectorate. On 29 September 1896 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory Of Papua And New Guinea
The Territory of Papua and New Guinea, officially the Administrative Union of the Territory of Papua and the Territory of New Guinea, was established by an administrative union between the Australian-administered territories of Papua and New Guinea (the latter being a United Nations trust territory administered by Australia) in 1949. In December 1971, the name of the Territory changed to "Papua New Guinea" and in 1975 it became the Independent State of Papua New Guinea. Background Ancient history Archeological evidence suggests that humans arrived on New Guinea around 50,000 years ago. These Melanesian people developed stone tools and agriculture. Portuguese and Spanish navigators sailing in the South Pacific entered New Guinea waters in the early part of the 16th century and in 1526–27, Jorge de Menezes came upon the principal island "Papua". In 1545, the Spaniard Iñigo Ortiz de Retes gave the island the name "New Guinea" because of what he saw as a resemblance between t ...

D'Entrecasteaux Islands
D'Entrecasteaux Islands () are situated near the eastern tip of New Guinea in the Solomon Sea in Milne Bay Province of Papua New Guinea. The group spans a distance of , has a total land area of approximately and is separated from the Papua New Guinea mainland by the wide Ward Hunt Strait in the north and the wide Goschen Strait in the south. D'Entrecasteaux Islands show signs of volcanism. People The inhabitants of D'Entrecasteaux Islands are indigenous subsistence horticulturalists living in small, traditional settlements. People of this area produced and traded clay pots as well as participated in the Kula exchange of shell valuables, travelling widely to other islands on sea-going sailing canoes. During the more recent past, people harvested copra, trochus and pearl-shells and some timber for cash. Alluvial gold mining was once important and in recent years the area has been subject to mineral exploration. Description The three principal islands, from northwest to sou ...
