First Results from Axial Seamount Underwater Volcano Eruption - 2015

Explore groundbreaking scientific findings from the 2015 eruption of Axial Seamount, an underwater volcano off the Oregon coast, in this 41-minute AGU press conference. Discover how researchers used a network of cabled sensors to track the onset and evolution of the volcanic event, revealing previously unknown structures and providing new insights into the volcano's internal workings. Learn about the National Science Foundation's Ocean Observatories Initiative and its role in monitoring this highly active underwater volcano. Gain a deeper understanding of volcanic processes, hazards, and their broader implications through presentations by experts from various institutions. Delve into topics such as magma dynamics, ring faults, seismic networks, hydrothermal chimneys, and the challenges of instrumenting underwater volcanoes. Uncover the unique observations made during the eruption, including mega plumes, steam explosions, and bacterial activity, and explore how these findings contribute to our knowledge of all volcanoes and their potential impacts.
