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 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 volcanism. The volcano is named for Richard S. Moulton, chief dog driver of the United States Antarctic Service Expedition; the western end of the Flood Range where Mount Mou ...

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 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 President Frankl ...

Mount Shasta
Mount Shasta ( Shasta: ''Waka-nunee-Tuki-wuki''; Karuk: ''Úytaahkoo'') is a potentially active volcano 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 fifth-highest in the state. Mount Shasta has an estimated volume of , which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc. The mountain and surrounding area are part of the Shasta–Trinity National Forest. Description 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 can be seen from the floor of the Central Valley to the south. The mountain has attracted the attention of poets, authors, and presidents. The mountain consists of four overlapping dormant volcanic cones that have built a complex shape, including the main summit and the prominent and visi ...

Ames Range
The Ames Range is an Antarctic range of snow-covered, flat-topped, steep-sided mountains, extending in a N-S direction for 32 km (20 mi) and forming a right angle with the eastern end of the Flood Range in Marie Byrd Land. They were discovered by the United States Antarctic Service Expedition (1939–41) and named by Richard E. Byrd for his father-in-law, Joseph Ames. The Ames Range consists of three coalescing shield volcanoes: Mount Andrus, Mount Kosciusko and Mount Kauffman, and Mount Boennighausen. Other Features There are several glaciers draining from the Ames Range: * Coleman Glacier * Jacoby Glacier * Rosenberg Glacier Other features include: * Brown Valley * Gardiner Ridge, connecting Mt. Kosciusko to Mt. Kauffman *Lind Ridge * Forrest Pass Forrest Pass () is a broad ice-filled pass between Mount Bursey, in the Flood Range, and the southern elevations of the Ames Range in Marie Byrd Land, Antarctica.

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 Kosciusko (Antarctica)
Mount Kosciusko is a mountain, rising to , that comprises the central portion 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, 1959–1965, and was named by the Advisory Committee on Antarctic Names for Captain Henry M. Kosciusko, U.S. Navy, Commander of the Antarctic Support Activities group, 1965–1967.

Mount Andrus
Mount Andrus is a shield volcano 3.2 km (2 mi) SE of Mount Boennighausen in the SE extremity of Ames Range, in Marie Byrd Land, Antarctica. Mapped by USGS from surveys and U.S. Navy air photos, 1964–68. Named by US-ACAN for Lt. Carl H. Andrus, US Navy, medical officer and Officer-in-Charge of Byrd Station in 1964. Andrus has a 4.5 km-wide caldera at its summit. The westward face of the mountain is drained by the Coleman Glacier, with significant crevassing present. 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. Named features Several features of Mount Bursey have been named by various groups of surveyors and explorers. Along the mountain's northwest margin lies Koerner Bluff, a bare rock bluff. Below Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that 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 period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
