Spotlight 1: Axial Seamount [PDF]
Oceanography, 2010 Axial Seamount is a hotspot volcano superimposed on the Juan de Fuca Ridge (JdFR) in the Northeast Pacific Ocean. Due to its robust magma supply, it rises ~ 800 m above the rest of JdFR and has a large elongate summit caldera with two rift zones that ...

The Magnetization of an Underwater Caldera: A Time‐Lapse Magnetic Anomaly Study of Axial Seamount
Geophysical Research Letters, 2022 Axial Seamount in the northeast Pacific erupted in 2015, 2011, and 1998. Although monitored by the Regional Cabled Array of the Ocean Observatory Initiative, few magnetic surveys have been conducted over the region.

Prospective April-May 2026 Seismic Pulse Windows at Axial Seamount
This note evaluates whether the developing April-May 2026 seismic pulse sequence at Axial Seamount is more consistent with an eruption-associated historical pattern or with a non-eruptive one. The analysis is framed as a prospective forecast supported by forensic comparison with two earlier cases: the 2015 Axial sequence, which was followed by eruption,

Triggering of eruptions at Axial Seamount, Juan de Fuca Ridge. [PDF]
Sci Rep, 2020 AbstractThe submarine volcano Axial Seamount has exhibited an inflation predictable eruption cycle, which allowed for the successful forecast of its 2015 eruption. However, the exact triggering mechanism of its eruptions remains ambiguous. The inflation predictable eruption pattern suggests a magma reservoir pressure threshold at which eruptions occur,

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
