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 ...
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 ...
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 ...
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.

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 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 ...
Axial Seamount is the hotspot's most recent eruptive center, which last erupted in 2015, 2011 and 1998. [3] [4] ...
