Alaska Volcano Observatory Alert and Forecasting Timeliness: 1989–2017
Frontiers in Earth Science, 2018 The Alaska Volcano Observatory (AVO) monitors volcanoes in Alaska and issues notifications and warnings of volcanic unrest and eruption. We evaluate the timeliness and accuracy of eruption forecasts for 53 eruptions at 20 volcanoes, beginning with Mount ...

Strong seismic reflections indicating possible eruptible magma beneath the Tatun Volcano Group in Taiwan [PDF]
Scientific ReportsThe Tatun Volcano Group (TVG), located at the northern tip of Taiwan, is situated near the Taipei metropolitan area. A future eruption of the TVG could have a significant impact not only on Taipei but also on the global economy, as Taiwan produces over ...

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano reached the mesosphere
Science, 2022 Explosive volcanic eruptions can loft ash, gases, and water into the stratosphere, which affects both human activities and the climate. Using geostationary satellite images of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, we find

Development of an open source Debris Flow Simulator for “Sabo” (DFSS) [PDF]
E3S Web of Conferences, 2023 We report the development of an open source “Debris Flow Simulator for Sabo” (DFSS). DFSS consists of three models corresponding to three geomorphological regions (mountain hillside slopes, mountain-to-plain river channels, and lower plains).

The Genesis of Molecular Volcano Plots.
Accounts of Chemical Research, 2021 ConspectusFor the past two decades, linear free energy scaling relationships and volcano plots have seen frequent use as computational tools that aid in understanding and predicting the catalytic behavior of heterogeneous and electrocatalysts.

Mathematics of Computation, 2010 Isogeny volcanoes are graphs whose vertices are elliptic curves and whose edges are $\ell$-isogenies. Algorithms allowing to travel on these graphs were developed by Kohel in his thesis (1996) and later on, by Fouquet and Morain (2001). However, up to now, no method was known, to predict, before taking a step on the volcano, the direction of this step.

Hydrothermal alteration can result in pore pressurization and volcano instability
Geology, 2021 The collapse of a volcanic flank can be destructive and deadly. Hydrothermal alteration is common to volcanoes worldwide and is thought to promote volcano instability by decreasing rock strength.

Frontiers in Earth Science, 2023 Ash is a potential sink of volcanically sourced atmospheric mercury (Hg), and the concentration of particle-bound Hg may provide constraints on Hg emissions during eruptions. We analyze Hg concentrations in 227 bulk ash samples from the Mount Spurr (1992)

Alteration‐Induced Volcano Instability at La Soufrière de Guadeloupe (Eastern Caribbean)
Journal of Geophysical Research: Solid Earth, 2021 Volcanoes are unstable structures that deform laterally and frequently experience mass wasting events. Hydrothermal alteration is often invoked as a mechanism that contributes significantly to volcano instability.
