Seismic constraints on caldera dynamics from the 2015 Axial Seamount eruption

Science, 2016
Volcano monitoring goes into the deep Axial Seamount is a large and active submarine volcano along the Juan de Fuca midocean ridge off the coast of the western United States. Eruptions in 1998 and 2011 were followed by periods of magma recharge, making it an ideal location to include in the Ocean Observatories Initiative Cabled ...

A microseismicity survey of Axial Seamount, Juan de Fuca Ridge

Bulletin of the Seismological Society of America, 1987
Abstract An array of ocean bottom seismometers and hydrophones were deployed within the caldera of Axial Seamount, located at the intersection of the Cobb-Eickelberg Seamount Chain and the Juan de Fuca Ridge. Recent manned submersible dives have discovered the presence of two distinct hydrothermal vent fields.

Compartmentalization of Axial Seamount's magma reservoir inferred by analytical and numerical deformation modeling with realistic geometry

Journal of Geophysical Research: Solid Earth, 2023
Axial Seamount is a submarine volcano on the Juan de Fuca Ridge with enhanced magma supply from the Cobb Hotspot. Here we compare several deformation model configurations to explore how the spatial component of Axial’s deformation time series relates to magma reservoir geometry imaged by multi-channel seismic (MCS) surveys.

Real-Time Detection of Volcanic Unrest and Eruption at Axial Seamount Using Machine Learning

Seismological Research Letters
Abstract Axial Seamount, an extensively instrumented submarine volcano, lies at the intersection of the Cobb–Eickelberg hot spot and the Juan de Fuca ridge. Since late 2014, the Ocean Observatories Initiative (OOI) has operated a seven-station cabled ocean bottom seismometer (OBS) array that captured Axial’s last eruption in April ...

Temporal Variation of Crustal Permeability in Relation to the Volcano Deformation Cycle at Axial Seamount, Northeast Pacific

Journal of Geophysical Research: Solid Earth
Abstract At some submarine volcanoes, the influx and output of magma vary over time producing years‐to‐decades‐long cycles of inflation and deflation, which in turn cause pronounced physical changes in the overlying oceanic crust and the hydrothermal circulation hosted within.
