![]() Simply said, Mount Erebus provides an ideal proxy for the study of volcanoes relatively simple mechanisms drive rare, accessible and spectaculars geological features. Tephra stratigraphy is consistent with Ross' observations and further suggests that the volcano's geological history is marked by explosive eruption events and is further reflected in the concentric caldera patterns. Upon the discovery of the Erebus volcano by Ross and his crew in 1847, reports describe an explosive eruption. The lithology points to a three stage building process: the shield building stage where the mantle plume would have been protruding the crust, a cone building stage where evolved lavas would have formed the flanks of the volcano and finally a marked increased lava forming stage forming the bulk of mount Erebus. Seismic velocity surveys suggest a thick layer (~5 km) of solidified phonolitic lava flows overlying cenozoic sediments and a basaltic basement. The surface geology of the volcano is almost entirely phonolitic anorthoclase. The age of the plume correlates both temporally and spatially with the Terror rift (see side note). Ross island itself is on the extensional rifting margin of the West Antarctic Plate, the north eastern terminus of Terror ridge. To the south, geological similarities suggests that brown peninsula would also have been a the product of the hypothesized Erebus hotspot. They all are though to be the product of crust thinning overlying a strong thermal anomaly and are consistent with a hotspot/mantle plume model. Mount Erebus, Antarctica s most active volcano, is. The standard cosmology of Greek myth comes from. He is the son of Chaos, who is also the mother of Erebus’s wife, Nyx, the personification of night. Erebus is one of the primordial beings in the Greek creation myth. The volcano and its neighbouring mountains, mount Bird to the north and mount Terror to the east, all reside on Ross Island. Erebus, also spelled Erebos, in Greek religion, the god of a dark region of the underworld and the personification of darkness. Cameras, microphones, seismic equipment as well as scientists from a wide range of fields all monitor mount Erebus. It has thus been subject of extensive research. Furthermore, irony has it, it is relatively easy to access. It's a popular backpacking destination in summer and fall due to trout fishing and some spectacular camping spots on (or near) the several high mountain ponds. It's wooded summit tops out at 2527', second in height to neighboring Black Mountain (2665') in this range. It is notable for its persistent convecting lava lakes with Strombolian eruptions projecting bombs up to 10 m in diameter in the last decades and its size -at 3794 m above sea level and ~200km km^3 in volume, it is among the largest volcanoes of the world . Erebus sits in the Eastern Adirondacks, overlooking Lake George. Mount Erebus is an alkaline stratovolcano just off the shore of the Antarctic main land (77 33'S, 167 10'E).
