Mount Moulton
Mount Moulton is a complex of ice-covered shield volcanoes, standing east of Mount Berlin in the Flood Range, Marie Byrd Land, Antarctica. It is named for Richard S. Moulton, chief dog driver at West Base. The volcano is of Pliocene age and is presently inactive. The Prahl Crags are located on the southern slopes of Mount Moulton and are part of a caldera. There, an exposed area of blue ice (glacial), blue ice can be found; this ice contains tephra layers from mainly neighbouring Mount Berlin volcano and some of the ice is almost half a million years old. Geology and geomorphology Mount Moulton lies in Marie Byrd Land of Western Antarctica and in the region of the West Antarctic Ice Sheet. It is part of a system of volcanoes including Mount Berlin, Mount Takahe and Mount Waesche as well as of recently active Subglacial volcano, subglacial volcanism. The volcano is named for Richard S. Moulton, chief dog driver of the United States Antarctic Service Expedition; the western en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Antarctic or Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of , including Eights Coast, immediately east of Marie Byrd Land. In 1939, United States ...

Mount Shasta
Mount Shasta ( ; Shasta people, Shasta: ''Waka-nunee-Tuki-wuki''; Karuk language, Karuk: ''Úytaahkoo'') is a Volcano#Volcanic activity, potentially active stratovolcano at the southern end of the Cascade Range in Siskiyou County, California. At an elevation of , it is the second-highest peak in the Cascades and the List of California fourteeners, fifth-highest in the state. Mount Shasta has an estimated volume of , which makes it the most voluminous stratovolcano in the Cascade Volcanoes, Cascade Volcanic Arc. The mountain and surrounding area are part of the Shasta–Trinity National Forest. Description The origin of the name "Shasta people#Origin of name, Shasta" is vague, either derived from a Shasta people, people of a name like it or otherwise garbled by early Westerners. Mount Shasta is connected to its satellite cone of Shastina, and together they dominate the landscape. Shasta rises abruptly to tower nearly above its surroundings. On a clear winter day, the mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwards Spur
The Flood Range () is a range of large snow-covered mountains extending in an east–west direction for about and forming a right angle with the southern end of the Ames Range in Marie Byrd Land, Antarctica. Location The Flood Range is south of the Hull Glacier and Kirkpatrick Glacier, which drain into Hull Bay on the Southern Ocean coast of Marie Byrd Land. The eastern end of the range is immediately south of the Ames Range. There are no named features in the ice sheet to the south of the range. The north slopes of the range form the western end of the Usas Escarpment. Discovery and name The Flood Range was discovered by the Byrd Antarctic Expedition (ByrdAE) in 1934 from a great distance. Reconnaissance flights by the United States Antarctic Service (USAS) (1939–41) explored the range. The principle mountain was named "Mount Hal Flood" by Richard E. Byrd for his uncle, the Hon. Henry D. Flood, U.S. Representative from Virginia. The name was subsequently transferred b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ames Range
The Ames Range () is a range of snow-covered, flat-topped, steep-sided mountains, extending in a north–south direction for and forming a right angle with the eastern end of the Flood Range in Marie Byrd Land, Antarctica. Location The Ames Range is northwest of the Mount Bursey massif in the Flood Range, from which it is separated by Forrest Pass, and southeast of the Berry Glacier and Demas Range. Glaciers draining the range include Coleman Glacier and Rosenberg Glacier on the west side, Jacoby Glacier on the east side and Herbst Glacier to the north. Peaks include Mount Andrus, Mount Boenninghausen, Mount Kosciusco and Mount Kauffman. Other features include Lind Ridge, Gardiner Ridge and Brown Valley. Discovery and naming The Ames Range was discovered by the United States Antarctic Service (USAS; 1939–41) and named by Richard E. Byrd for his father-in-law, Joseph Ames. Geology The Ames Range consists of three coalescing shield volcanoes: Mount Andrus, Mount Kosciusko an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Kauffman
Mount Kauffman is a prominent mountain, high, that surmounts the northwest end of the Ames Range in Marie Byrd Land, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–65, and named by the Advisory Committee on Antarctic Names for Commander S.K. Kauffman, U.S. Navy, a staff civil engineering officer who supervised the planning and building of Plateau Station, 1965–66. It is connected to Mount Kosciusko by Gardiner Ridge which is at one end of Brown Valley. Kauffman consists of a potentially active shield volcano with a wide summit caldera.

Mount Andrus
Mount Andrus () is a peak southeast of Mount Boennighausen in the southeast extremity of the Ames Range, in Marie Byrd Land, Antarctica. Mapping and name Mount Andrus was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs, 1964–68. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Lt. Carl H. Andrus, United States Navy, medical officer and Officer-in-Charge of Byrd Station in 1964. Geology Mount Andrus is the youngest of the shield volcanoes in the Ames Range, which formed during the Miocene. Late-stage volcanic activity resumed at Mount Andrus in the late Pleistocene or the Holocene. Its has a wide caldera at its summit. While the age of Mt. Andrus is not well known it is one of the oldest trachytic shield volcanoes in Marie Byrd Land, similar in age to Mount Hampton.

Mount Bursey
Mount Bursey is a broad, ice-covered mountain, high, which forms the eastern end of the Flood Range in Marie Byrd Land, Antarctica. It was discovered by members of the United States Antarctic Service (USAS) on aerial flights in 1940, and named for Jacob Bursey, member of the Byrd Antarctic Expedition (1928–30) and dog-driver with the USAS party which sledged to the west end of the Flood Range in December 1940. Volcanism Mount Bursey consists of two coalescing shield volcanoes, namely Hutt Peak and Koerner Bluff. Each shield contains a diameter caldera at its summit. Potassium–argon dating has indicated both shields formed during the Miocene epoch, with volcanism at Hutt Peak occurring as recently as 0.49 million years ago. Starbuck Crater is a volcanic cone on the mountain. See also * List of volcanoes in Antarctica This is a list of volcanoes in Antarctica.

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
