Dynamics of the 2021 Fagradalsfjall Eruption (Iceland) Revealed by Volcanic Tremor Patterns

Journal of Geophysical Research - Solid Earth
Co‐eruptive volcanic tremor during the 2021 Fagradalsfjall eruption in Iceland (19 March–18 September 2021) is characterized using seismic and visual data recorded close to the eruption site and across the Reykjanes Peninsula.

Temporal variation in source location of continuous tremors before ash–gas emissions in January 2014 at Aso volcano, Japan

Earth, Planets and Space, 2018
Volcanic tremor is often observed to be associated with an increase in volcanic activity and during periods approaching eruptions. It is therefore of crucial importance to study this phenomenon.

Relation Between Volcanic Tremor and Geodetic Strain Signals During Basaltic Explosive Eruptions at Etna

Journal of Geophysical Research - Solid Earth
Volcano deformation and seismicity during basaltic explosive eruptions are the expressions of the processes that regulate magma ascent from depth to surface.

TREMOrEC: A software utility for automatic classification of volcanic tremor [PDF]

, 2008
We describe a stand-alone software utility named TREMOrEC, which carries out training and test of a Support Vector Machine (SVM) classifier. TREMOrEC is developed in Visual C++ and runs under Microsoft Windows operating systems.

Differential Phase Analysis for Volcanic Tremor Detection and Source Location

Journal of Geophysical Research - Solid Earth
We present observations showing that during episodes of volcanic tremors, the phase of inter‐station cross‐correlations becomes stable. We propose a new quantity, the phase coherence, to identify the differential phase stability in recordings obtained ...

Seismic monitoring of Campi Flegrei and Vesuvius by stand-alone instruments

Annals of Geophysics, 2015
A seismic network of more than 20 broad band stations and two arrays of 10 short period stations each, all working in local acquisition mode, are used to improve the seismic monitoring of Campi Flegrei and Vesuvius for research purposes. Data provided by

A Physical Model for Volcanic Eruption Tremor

Journal of Geophysical Research: Solid Earth, 2020
AbstractSeismic waves are commonly used to monitor unrest before, during, and after volcanic eruptions. The source of seismic tremor during a sustained explosive volcanic eruption is not well understood. Recent observations of the 2016 eruption of Pavlof Volcano, Alaska, revealed a change in the relationship (hysteresis) between ash plume height and ...

PLXDC2 siRNA‐Mediated Intervention Attenuates Microglial Senescence Through cGAS‐STING Signaling

Advanced Science, EarlyView.
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...
