The base of Axial Seamount is a long, low-lying plateau, and the eastern part of the seamount is defined by a series of linear scarps. Axial Seamount has two major volcanic rifts extending approximately 50 km (31 mi) north and south of its main summit, as well as several much smaller, ill-defined ones aligned in a roughly similar pattern.
1. Axial Seamount (46° 03′ 36″ N, 130° 00′ 0″ W). The most recent seamount. Axial Seamount is the youngest seamount in the Cobb Eickelberg Seamount chain. Since this is the most active of all the Cobb-Eickelberg Seamounts, it is studied the most: to help understand the dynamics of seamounts, volcanic activity, earthquakes, biodiversity, geology and chemistry.
A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
Axial Seamount is the hotspot's most recent eruptive center, which last erupted in 2015, 2011 and 1998. [3] [4] The central ridge of the hotspot is thicker than the ...
Map of world's major seamounts.. A list of active and extinct submarine volcanoes and seamounts located under the world's oceans. There are estimated to be 40,000 to 55,000 seamounts in the global oceans. [1]
Researchers at Oregon State University suggested the Axial Seamount had an eruption interval of approximately 16 years, which would place the next major Axial eruption in 2014. [12] In 2011, during a dive on the seamount, new lava flows were discovered and some instruments had been buried in lava flows, indicating the volcano had erupted since ...
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island, islet or Cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
