Inflation-predictable behavior and co-eruption deformation at Axial Seamount
Science, 2016Volcano 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 ...

Volcanic action at Axial Seamount
Nature, 2000Axial Seamount is an underwater volcano that lies on a seafloor-spreading centre off the west coast of southern Canada. It is being intensively studied, both through continuous monitoring by instruments at or near the site and through ship-borne ‘event response’ visits by scientists. The most recent burst of volcanic activity at Axial Seamount happened

Observing and interpreting seafloor tilt at Axial Seamount
2020Measurements of ground tilt are a critical geodetic tool for monitoring active volcanoes because they provide multidimensional data that can resolve complex deformation signals.

Seismic constraints on caldera dynamics from the 2015 Axial Seamount eruption
Science, 2016Volcano 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 ...

Axial Seamount: A Wired Submarine Volcano Observatory in the NE Pacific
2021<p>Axial Seamount is the most active submarine volcano in the NE Pacific Ocean, and is monitored by instruments connected to a cabled observatory (the US Ocean Observatories Initiative Cabled Array), supplemented by autonomous battery-powered instruments on the seafloor at ~1500 m depth.&#160; Axial Seamount is a basaltic hot spot

A microseismicity survey of Axial Seamount, Juan de Fuca Ridge
Bulletin of the Seismological Society of America, 1987Abstract 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.

Stacked sills forming a deep melt-mush feeder conduit beneath Axial Seamount
Geology, 2020Abstract Magmatic systems are composed of melt accumulations and crystal mush that evolve with melt transport, contributing to igneous processes, volcano dynamics, and eruption triggering. Geophysical studies of active volcanoes have revealed details of shallow-level melt reservoirs, but little is known about fine-scale melt distribution

The magnetic structure of Axial Seamount, Juan de Fuca Ridge
Journal of Geophysical Research: Solid Earth, 1990Axial Seamount is a large, volcanically active seamount located in the eastern Pacific on the central Juan de Fuca (JDF) ridge at 46°N, 130′W. Sea surface magnetic anomaly data show that Axial lies completely within crust formed during the Brunhes normal polarity epoch.

Dynamic magma movements beneath the Axial Seamount revealed by Rayleigh-wave Admittance Method
2023Investigation of the dynamic magma movement beneath the volcanos could provide critical information about the mechanism of volcanic eruption and therefore enhance the accuracy of eruption forecast.  Axial Seamount is an active submarine volcano located at the intersection of the Juan de Fuca Ridge and the Cobb hotspot.

Seafloor deformation and forecasts of the April 2011 eruption at Axial Seamount
Nature Geoscience, 2012The Axial Seamount submarine volcano exhibits an inflation–deflation cycle comparable to similar volcanoes on land. Measurements of ocean bottom pressure document the entire inflation–deflation cycle between eruptions at Axial Seamount in 1998 and 2011, and imply that the timing of submarine eruptions could be more predictable than that of their ...
