European climate response to tropical volcanic eruptions over the last half millennium [PDF]

open access: yes, 2007
We analyse the winter and summer climatic signal following 15 major tropical volcanic eruptions over the last half millennium based on multi-proxy reconstructions for Europe. During the first and second post-eruption years we find significant continental

STP: What about dynamics?

open access: yes, 1999
The origin of volcanic tremor is still the subject of vigorous scientific debate. One of the most recent models, by Ripepe and Gordeev, suggests that volcanic tremor is related to the coalescence of bigger gas bubbles from a layer of smaller ones in the ...

Observations of rapid-fire event tremor at Lascar volcano, Chile

open access: yesAnnals of Geophysics, 1996
During the Proyecto de Investigaciòn Sismològica de la Cordillera Occidental (PISCO '94) in the Atacama desert of Northern Chile, a continuously recording broadband seismic station was installed to the NW of the currently active volcano, Lascar.

Nitrogen dynamics 35 years after stand‐replacing fire: Aboveground pools grow as surface soil pools remain unchanged

open access: yesEcology, Volume 107, Issue 10, October 2026.
Abstract Natural disturbances induce variable recovery pathways, and long‐term studies are key to understanding how that variability affects ecosystem function over time and across space. In subalpine forests, high‐severity wildfires produce high variability in postfire tree density, but how this variability relates to nitrogen (N) cycling remains ...

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

open access: yesGeophysical Research Letters
An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis.

Illuminating the Transition From an Open to a Semi‐Closed Volcanic Vent System Through Episodic Tremor Duration and Shape

open access: yesJournal of Geophysical Research - Solid Earth
[Volcanic eruptions generate continuous or episodic tremor, which can provide unrivaled information about activity changes during eruption. However, the wealth of information in episodic tremor patterns is often not harvested and transitions between ...

Trigonelline Alleviates Neuroinflammation in AAV‐SynA53T Parkinson's Disease Model Mice: Involvement of PI3K/AKT–NF‐κB Signaling and Gut Microbial‐Metabolic Remodeling

open access: yesFood Science &Nutrition, Volume 14, Issue 10, October 2026.
Trigonelline alleviated motor deficits, α‐synuclein‐associated pathology, and neuroinflammatory changes in AAV‐SynA53T mice. These effects were accompanied by reduced PI3K/AKT–NF‐κB signaling activity, improved intestinal barrier‐associated features, and gut microbiota–metabolome remodeling.

A Method for Monitoring of Discharge Volume of Volcanic Ash by Using Volcanic Tremor [PDF]

open access: yes, 2013
A method for estimation of amount of volcanic ash ejected by explosive eruption at Showa crater of Sakurajima volcano is proposed. Volcanic tremor is observed associated with continuous ejection of volcanic ash.

Automatic non-volcanic tremor detection in the Mexican subduction zone [PDF]

open access: yesGeofísica Internacional, 2010
An automatic non-volcanic tremor (NVT) detection algorithm is developed. NVT occurs in the 1 – 10 Hz frequency range, but high ambient noise dominates above 2 Hz at many of the MesoAmerican Seismic Experiment (MASE) stations, so the seismograms are ...
