Submarine ash megabed fed by far-traveled, shoreline-crossing pyroclastic currents from a large explosive volcanic eruption. [PDF]
Sci AdvLarge explosive volcanic eruptions from island volcanoes deliver vast quantities of ash to the marine environment. While many of the transport pathways are understood, those from shoreline-crossing or submarine pyroclastic currents, and their ...

Frontiers in Earth Science, 2023 Sudden changes of eruption styles and magma compositions at arc volcanoes are enigmatic processes. Nishinoshima volcano, western Pacific, has had historical eruptions in 1973–1974 and from 2013 on and off to the present day.

Submarine Volcanic Eruptions and Their Impacts on Hydrothermal Systems and Biological Communities
Annual Review of Earth and Planetary SciencesMore than 70% of Earth's magmatic output occurs in the ocean. This volcanism shapes major features of the seafloor, directly impacts the chemical composition of the oceans through water/rock interactions, and drives hydrothermal circulation of seawater ...

Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions [PDF]
Oceanography, 2014 The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict these types of eruptions. Monitored by local seismometers

Submarine cores record magma evolution toward a catastrophic eruption at Kikai Caldera
Communications Earth & EnvironmentMagma evolution toward a caldera-forming eruption remains uncertain in many cases owing to the lack of successive volcanic records before catastrophic eruptions.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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.

Asymmetric magma plumbing system beneath Axial Seamount based on full waveform inversion of seismic data [PDF]
Nature CommunicationsThe architecture of magma plumbing systems plays a fundamental role in volcano eruption and evolution. However, the precise configuration of crustal magma reservoirs and conduits responsible for supplying eruptions are difficult to explore across most ...
