A two-layer shallow flow model with two axes of integration, well-balanced discretization and application to submarine avalanches [PDF]

open access: yes, 2020
We propose a two-layer model with two different axes of integration and a well-balanced finite volume method. The purpose is to study submarine avalanches and generated tsunamis by a depth-averaged model with different averaged directions for the fluid ...

Origin of the Ionospheric Changes Immediately Before the 15 January 2022 Eruption of the Hunga-Tonga Hunga-Ha’apai Submarine Volcano

open access: yesAtmosphere
Near-field ionospheric total electron content records before and after the 15 January 2022 eruption of the Hunga-Tonga Hunga-Ha’apai submarine volcano were studied using GNSS total electron content data.

Neotectonics of the Sumatran fault, Indonesia [PDF]

open access: yes, 2000
The 1900-km-long, trench-parallel Sumatran fault accommodates a significant amount of the right-lateral component of oblique convergence between the Eurasian and Indian/Australian plates from 10°N to 7°S.

Clay Mineral Suites in Submarine Mud Volcanoes in the Kumano Forearc Basin, Nankai Trough: Constraints on the Origin of Mud Volcano Sediments

open access: yesGeosciences, 2018
Clay mineralogy is an important characteristic of mud volcano sediments. This study determined the clay mineral compositions of sediment from two submarine mud volcanoes in the Kumano forearc basin, Nankai Trough, by X-ray diffraction analysis.

Cenozoic sedimentary and volcanic rocks of New Zealand: A reference volume of lithology, age and paleoenvironments with maps (PMAPs) and database. [PDF]

open access: yes, 2015
This volume presents descriptive geological data and text about each Cenozoic sedimentary and volcanic geological unit to formation and member level (in some cases) exposed on land in New Zealand, including their lithology, stratigraphic age and inferred

The thermal properties of submarine rhyolite lavas from Havre volcano (Kermadec arc, Pacific Ocean)

open access: yesVolcanica
The thermal properties of lavas are required for modelling volcanic and hydrothermal processes, yet are scarce for submarine lavas. Laboratory experiments, using the transient hot-strip method, are used to understand the role of porosity, glass content ...

IMPACT AND RESPONSE IN CENTRAL AND SOUTH AMERICA DUE TO THE TSUNAMI GENERATED BY THE SUBMARINE ERUPTION OF HUNGA TONGA-HUNGA HA’APAI VOLCANO [PDF]

open access: yesScience of Tsunami Hazards, 2022
Th Hunga Tonga-Hunga Ha'apai submarine volcano erupted on Saturday 15, 2022 leading to a VEI 5 eruption at 17.27 local time, shaking the earth with a M5.8. As result of this explosion a tsunami was triggered.

Introduction to special section: Hawaii Scientific Drilling Project [PDF]

open access: yes, 1996
Intraplate or "hot spot" volcanic island chains, exemplified by Hawaii, play an important role in plate tectonic theory as reference points for absolute plate motions, but the origin of these volcanoes is not explained by the plate tectonic paradigm ...

Deep drilling into a Hawaiian volcano [PDF]

open access: yes, 2001
Hawaiian volcanoes are the most comprehensively studied on Earth. Nevertheless, most of the eruptive history of each one is inaccessible because it is buried by younger lava flows or is exposed only below sea level.
