Prevalence of Seismic Rate Anomalies Preceding Volcanic Eruptions in Alaska

Frontiers in Earth Science, 2018
Seismic rate increases often precede eruptions at volcanoes worldwide. However, many eruptions occur without such precursors. Additionally, identifying seismic rate increases near volcanoes with high levels of background seismicity is non-trivial and ...

Forecasting Eruptions at Restless Calderas

Eos, 2016
Scientists review decades of data on swarms of earthquakes, surface deformation, degassing, and microgravity changes around calderas to determine when such forms of unrest may result in eruptions.

Forecasting volcanic eruptions from seismic data [PDF]

Bulletin Volcanologique, 1971
An increase in cumulative seismic strain release from volcanic earthquakes prior to eruptions of Bezymyanniy Volcano in 1955–1961 and Sheveluch Volcano in 1964 in Kamchatka, and of Tokachi-dake Volcano on Hokkaido Island in 1962 occurred in accordance with a hyperbolic law. The relationship obtained may be universal for andesite volcanoes.

Training in crisis communication and volcanic eruption forecasting: design and evaluation of an authentic role-play simulation

Journal of Applied Volcanology, 2015
We present an interactive, immersive, authentic role-play simulation designed to teach tertiary geoscience students in New Zealand to forecast and mitigate a volcanic crisis.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Short-Term Seismic Precursors to Icelandic Eruptions 1973–2014

Frontiers in Earth Science, 2018
Networks of seismographs of high sensitivity have been in use in the vicinity of active volcanoes in Iceland since 1973. During this time, 21 confirmed eruptions have occurred and several intrusions where magma did not reach the surface. All these events

The role of science in physical natural hazard assessment : report to the UK Government by the Natural Hazard Working Group [PDF]

, 2005
Following the tragic Asian tsunami on 26 December 2004, the Prime Minister asked the Government’s Chief Scientific Adviser, Sir David King, to convene a group of experts (the Natural Hazard Working Group) to advise on the mechanisms that could and ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Renewed Explosive Phreatomagmatic Activity at Poás Volcano, Costa Rica in April 2017

Frontiers in Earth Science, 2018
Phreatic and phreatomagmatic eruptions at volcanoes often present no short term precursory activity, making them a challenge to forecast. Poás volcano, Costa Rica, exhibits cyclic activity with phreatic and some phreatomagmatic eruptions separated by ...
