The 1998 eruption of Axial Seamount was preceded by several large earthquake swarms, common indicators of volcanic activity. The swarms correlated to magma movements in the volcano; bottom pressure recorders deployed on the volcano between 1987 and 1992 recorded five instances of deflation in the summit surface (caused by lava movement ...
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.
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 ] Almost all are not well-mapped and many may not have been identified at all.
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.
The Axial Seamount, an underwater volcano located about 300 miles off the coast of Oregon, is displaying behavior that indicates an eruption is imminent in 2025, William Chadwick, research ...
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 ...
