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

Universal machine learning approach to volcanic eruption forecasting using seismic features
Frontiers in Earth ScienceIntroduction: Volcano seismology has successfully predicted several eruptions and includes many reliable methods that have been adopted extensively by volcanic observatories; however, there are several problems that still lack solutions.

Event trees for eruption forecasting at Vesuvius volcano
, 2020 A probabilistic approach is used to forecast a future eruption at Vesuvius volcano. Such approach, differently from a deterministic one, allows to account for spatial and temporal variability of eruptive style (effusive, explosive), event magnitude ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State
American Journal of Botany, EarlyView.Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Ground-Based Measurements of the 2014–2015 Holuhraun Volcanic Cloud (Iceland)
Geosciences, 2018 The 2014–2015 Bárðarbunga fissure eruption at Holuhraun in central Iceland was distinguished by the high emission of gases, in total 9.6 Mt SO2, with almost no tephra.

The Anatomical Record, EarlyView.We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Could Kı̄lauea's 2020 Post Caldera‐Forming Eruption Have Been Anticipated?
Geophysical Research Letters, 2022 In 2018 Kı̄lauea volcano erupted a decade's worth of basalt, given estimated magma supply rates, triggering caldera collapse. Yet, less than 2.5 years later Kı̄lauea re‐erupted. At the 2018 eruption onset, pressure within the summit reservoir was ∼20 MPa

The Anatomical Record, EarlyView.Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Frontiers in Earth Science, 2018 Volcanic eruptions occur when a conduit forms to connect a crustal magma reservoir to Earth’s surface. Conduit formation is generally assumed to be a ‘bottom-up’ process and a major driver of precursory volcanic seismicity, which is the most commonly ...

Fracture mechanics of volcanic eruptions [PDF]
, 2009 Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.
