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 ...

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

Geological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

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.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

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

Understanding Autistic Young Adults' Perceptions and Experiences of Traumatic and Stressful Events

Journal of Clinical Psychology, Volume 81, Issue 6, Page 445-461, June 2025.
ABSTRACT Objectives The aim of this study was to explore how young autistic adults experience and respond to stressful life events, and the relationship between autistic characteristics and symptoms of stress associated with these events. Methods Using an exploratory sequential mixed‐methods approach, an online qualitative survey was first administered

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 ...
