Mount St. Helens Retrospective: Lessons Learned Since 1980 and Remaining Challenges

open access: yesFrontiers in Earth Science, 2018
Since awakening from a 123-year repose in 1980, Mount St. Helens has provided an opportunity to study changes in crustal magma storage at an active arc volcano—a process of fundamental importance to eruption forecasting and hazards mitigation.

Eruptive Event Generator Based on the Gibson-Low Magnetic Configuration [PDF]

open access: yes, 2017
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one of the primary means of studying ...

Eruption forecast for Krafla Caldera

open access: yesEos, Transactions American Geophysical Union, 1982
Since December 1975, Krafla, a volcano in northern Iceland, has been the site of repeated earthquakes, fissuring, and occasional eruptions (see cover figure). Intense monitoring of activity at Krafla has led to the recognition of a repetitive pattern of months‐long inflation in the caldera area, followed by sudden deflation.

Towards scientific forecasting of magmatic eruptions

open access: yesNature Reviews Earth & Environment, 2023
Forecasting eruptions is a fundamental goal of volcanology. However,difficulties in identifying eruptive precursors, fragmented approachesand lack of resources make eruption forecasting difficult to achieve.In this Review, we explore the first-order scientific approaches thatare essential to progress towards forecasting the time and location ofmagmatic

Accurate hindcasting of explosive eruptions at Whakaari, New Zealand

open access: yesVolcanica
Phreatic eruptions are small, sudden events, commonly with few precursory signals. They are driven by interactions between magmatic and hydrothermal processes at shallow levels beneath the surface.

Short-Term Forecasting and Detection of Explosions During the 2016–2017 Eruption of Bogoslof Volcano, Alaska

open access: yesFrontiers in Earth Science, 2018
We describe a multidisciplinary approach to forecast, rapidly detect, and characterize explosive events during the 2016–2017 eruption of Bogoslof volcano, a back-arc shallow submarine volcano in Alaska’s Aleutian arc.

Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013-14 [PDF]

open access: yes, 2019
Eruptions of Sinabung volcano, Indonesia have been ongoing since 2013. Since that time, the character of eruptions has changed, from phreatic to phreatomagmatic to magmatic explosive eruptions, and from production of a lava dome that collapsed to a ...

Hindcasting Magma Reservoir Stability Preceding the 2008 Eruption of Okmok, Alaska

open access: yesGeophysical Research Letters, 2019
Volcanic eruptions pose a significant and sometimes unpredictable hazard, especially at systems that display little to no precursory signals. For example, the 2008 eruption of Okmok volcano in Alaska notably lacked observable short‐term precursors ...

Eruptive Styles Recognition Using High Temporal Resolution Geostationary Infrared Satellite Data

open access: yesRemote Sensing, 2019
The high temporal resolution of the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) instrument aboard Meteosat Second Generation (MSG) provides the opportunity to investigate eruptive processes and discriminate different styles of volcanic ...

Thermal Remote Sensing for Global Volcano Monitoring: Experiences From the MIROVA System

open access: yesFrontiers in Earth Science, 2020
Volcanic activity is always accompanied by the transfer of heat from the Earth’s crust to the atmosphere. This heat can be measured from space and its measurement is a very useful tool for detecting volcanic activity on a global scale.
