1975 Near Islands Earthquake
{{Earthquake-stub ...
The 1975 Near Islands earthquake occurred at 08:43 UTC on February 2 off the coast of Attu Island, Alaska. The earthquake had a surface wave magnitude of 7.6 and a maximum Mercalli intensity of IX (''Violent''). It caused heavy damage on Shemya Island, injuring 15 residents. The runways of Shemya Air Force Base sustained cracks up to wide, and crevices with as much as of displacement were observed on the island.

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, ...

Attu Island
Attu ( ale, Atan, russian: Атту, link=no) is an island in the Near Islands (part of the Aleutian Islands chain). It is the westernmost point of the U.S. state of Alaska. The island became uninhabited in 2010, making it the largest uninhabited island to be politically part of the United States. (archived June 25, 2017) The Battle of Attu was the site of the only World War II land battle fought in the United States. The battlefield area is a U.S. National Historic Landmark. Attu Station, a former Coast Guard LORAN station, is located at , making it one of the westernmost points of the United States relative to the rest of the country. However, since it is in the Eastern Hemisphere, being on the opposite side of the 180° longitude line of the contiguous 48 states, it can also be considered one of the easternmost points of the country (a second Aleutian Island, Semisopochnoi Island at 179°46′E, is the easternmost location in the United States by this definition).

Surface Wave Magnitude
The surface wave magnitude (M_s) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. It is currently used in People's Republic of China as a national standard (GB 17740-1999) for categorising earthquakes. Recorded magnitudes of earthquakes through the mid 20th century, commonly attributed to Richter, could be either M_s or M_L. Definition The formula to calculate surface wave magnitude is: :M_s = \log_\left(\frac\right)_ + \sigma(\Delta)\,, where A is the maximum particle displacement in surface waves (vector sum of the two horizontal displacements) in μm, T is the corresponding period in s (usually 20 2 seconds), Δ is the ep ...

Shemya Island
Shemya or Simiya ( ale, Samiyax̂) is a small island in the Semichi Islands group of the Near Islands chain in the Aleutian Islands archipelago southwest of Alaska, at . It has a land area of , and is about southwest of Anchorage, Alaska. It is wide and long. History The Russian vessel ''Saint Peter and Paul'' wrecked at Shemya in 1762. Most of the crew survived. A United States Air Force radar, surveillance, and weather station and aircraft refueling station, including a runway, opened on Shemya in 1943 and is still in operation. The station, originally Shemya Air Force Base or Shemya Station, had 1,500 workers at its peak in the 1960s. In 1956, Northwest Airlines leased Shemya Island from the U.S. government to use as a refueling station on their North Pacific route. According to Northwest's website, that made them "the first airline to operate its own airport." Northwest was operating Lockheed Constellation L-1049G model propliners on its "Orient Express" service between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shemya Air Force Base
Eareckson Air Station , formerly Shemya Air Force Base, is a United States Air Force military airport located on the island of Shemya, in the Alaskan Aleutian Islands. The airport was closed as an active Air Force Station on 1 July 1994. However, it is still owned by the USAF and is operated by the USAF 611th Air Support Squadron at Elmendorf AFB for refueling purposes. It also serves as a diversion airport for civilian aircraft. The base previously hosted the AN/FPS-17 and AN/FPS-80 radars and since 1977 the more powerful AN/FPS-108 COBRA DANE phased-array radar. Overview Eareckson Air Station is located on the western tip of Alaska's Aleutian islands near the larger island of Attu, lying approximately 1500 miles southwest of Anchorage. The airport lies on the south side of the 2-mile by 4-mile island and is 98 feet above mean sea level. Shemya Island has been the scene of two major earthquakes. The 1965 Rat Islands earthquake, measuring 8.7 on the moment magnitude scale, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
