Mid‐Ocean Ridge (MOR) Ash Dispersal on Axial Seamount, Juan de Fuca Ridge Open
Rare eruption of primitive normal mid‐ocean ridge basalt (N‐MORB) magma (∼9.5 wt% MgO) on the summit of Axial Seamount generated abundant ash that was dispersed for several km. The unique geochemical signature of this ash deposit is distin…

A highly diverse silicic end member of a bimodal magma suite formed in an active continental back arc, Okinawa Trough Open
<p>The Okinawa Trough (OT) is an incipient continental back-arc basin that extends from Kyushu in the north to Taiwan in the south. The Okinawa Trough can be split in to three segments, the Northern (NOT), Middle (MOT), and Southern …

Volcaniclastic Dispersal During Submarine Lava Effusion: The 2012 Eruption of Havre Volcano, Kermadec Arc, New Zealand Open
Understanding clast dispersal from subaqueous volcanism is hampered by uncertainty in the source and extent of seafloor deposits. Extensive sampling in situ of seafloor deposits from the 2012 submarine eruption of Havre volcano provides an…

Characteristics and Deposit Stratigraphy of Submarine-Erupted Silicic Ash, Havre Volcano, Kermadec Arc, New Zealand Open
Submarine eruptions dominate volcanism on Earth, but few are observed or even identified. Knowledge of how they operate is largely based on inference from ancient deposits, lagging by a decade or more our understanding of subaerial eruptio…

Fragmentation experiments with Havre melt: dry and induced fuel-coolant interaction runs Open
Here we present the data records (raw data) from 19 fragmentation experiments. In these runs silicic HVR254 dome rock (retrieved from the submarine Havre volcano) was crushed, remelted and fragmented using two different experimental settin…

PARTIcle Shape ANalyzer PARTISAN – an open source tool for multi-standard two-dimensional particle morphometry analysis Open
In volcanology, 2D morphometric analysis is a method often applied for quantitative characterization of eruptive products, used to compare tephra from different events or phases, infer eruptive styles and underlying clast generating mechan…

The largest deep-ocean silicic volcanic eruption of the past century Open
A submersible study of the products of a large submarine eruption demonstrates the influence of the ocean on eruption dynamics.

Ash Generation in the 2012 Eruption of Havre Volcano, Kermadec Arc: The Largest Deep Subaqueous Eruption of the Last Century Open
The 2012 silicic eruption at Havre volcano, in the Kermadec Arc, was the largest deep subaqueous eruption observed in the last century. A data set of unprecedented richness was collected during a dedicated research cruise in 2015, includin…
