Multidisciplinary Constraints on Magma Compressibility, the Pre‐Eruptive Exsolved Volatile Fraction, and the H2O/CO2 Molar Ratio for the 2006 Augustine Eruption, Alaska

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Geodetically modeled reservoir volume changes during volcanic eruptions are commonly much smaller than the observed eruptive volumes. This discrepancy is thought to be partially due to the compressibility of magma, which is largely controlled by the ...

Probabilistic Source Classification of Large Tephra Producing Eruptions Using Supervised Machine Learning: An Example From the Alaska‐Aleutian Arc

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Alaska contains over 130 volcanoes and volcanic fields that have been active within the last 2 million years. Of these, roughly 90 have erupted during the Holocene, with many characterized by at least one large explosive eruption.

Magma-Carbonate Interaction at Merapi Volcano, Indonesia

open access: yes, 2023
Merapi volcano, Indonesia, is a highly active arc volcano built upon a crustal succession that includes thick carbonate sequences. Calc-silicate (skarn) xenoliths are frequently found in Merapi’s erupted products and constitute direct evidence for magma ...

Debris-flow monitoring on volcanoes via a novel usage of a laser rangefinder

open access: yesJournal of Applied Volcanology
Mount Rainier has had at least 11 large lahars over the last 6,000 years, including one occurring without evidence of eruptive activity. This prompted the creation of a lahar detection system that uses a combination of seismic, infrasound, and tripwires.

Monitoring eruption activity using temporal stress changes at Mount Ontake volcano

open access: yesNature Communications, 2016
Volcanic activity is often accompanied by small earthquakes, with focal mechanisms indicating stress state beneath volcanoes. Here, the authors demonstrate that quantitative evaluation of temporal stress changes is an effective tool for eruption ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Evaluation of Pelletized Artificial Geopolymer Aggregate Manufactured From Volcano Ash [PDF]

open access: yes, 2013
This paper introduced the new pelletized artificial geopolymer aggregate made from volcano ash. This is one of the effort to diminish the high quantity of volcano mud from East Java, Indonesia, that become a major issue since May 29, 2006 when it ...

Following the tug of the audience from complex to simplified hazards maps at Cascade Range volcanoes

open access: yesJournal of Applied Volcanology
Volcano-hazard maps are broadly recognized as important tools for forecasting and managing volcanic crises and for disseminating spatial information to authorities and people at risk.
