A “fascinating” eruption is approaching as a sleeping giant underwater volcano stirs with seismic activity near America’s west coast.. The seismic activity of Axial Seamount, a submerged ...
The Axial Seamount is a massive undersea volcano that reaches more than 3,600 feet above the seabed, 300 miles offshore. It last erupted in 2015 but has a history of more than 50 different ...
Axial Seamount is a shield volcano, which means it's shaped like a shield rather than a steep-sided cone volcano. Its caldera at the top is a few miles wide and long, and about 300 feet deep.
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.
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]
The Axial Seamount tends to expel "controlled" eruptions about a mile beneath the sea surface -- deep enough and far enough away from the coast that it won't threaten human lives, Scott Nooner, a ...
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 ...
