Reactivation of dormant Edgecumbe volcano, Alaska

Reactivation of dormant Edgecumbe volcano, Alaska

Researchers reporting in AGU’s Geophysical Research Letters show that the seismic swarm detected near Mt. Edgecumbe volcano in Southeast Alaska, U.S. in April 2022 was caused by magmatic activity taking place under this transform fault volcano previously considered dormant.

Lava field in Lanzarote twice as thick as previously thought, Canary Islands

Lava field in Lanzarote twice as thick as previously thought, Canary Islands

An international group of researchers reporting in AGU’s Geochemistry, Geophysics, Geosystems used radar satellites to measure how fast parts of the lava fields in Lanzarote, Canary Islands are sinking nearly three centuries after a massive eruption that lasted from 1730 – 1736.

Predicting earthquakes using ionospheric total electron content anomalies- study

Predicting earthquakes using ionospheric total electron content anomalies- study

A new study published recently in Remote Sensing proposes the implementation of machine learning support vector machine (SVM) technique, applied with GPS ionospheric total electron content (TEC) pre-processed time series estimations, to evaluate potential precursors caused by earthquakes.

How solar storms affect railway signals

How solar storms affect railway signals

A project investigating the effect of solar storms on railway signals, presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a PhD student at Lancaster University, shows how fluctuations in space weather are disrupting train signals and causing significant delays.

Magmatic degassing in Campi Flegrei in recent bradyseismic crises, Italy

Magmatic degassing in Campi Flegrei in recent bradyseismic crises, Italy

A new study published in AGU’s JGR Solid Earth combined the petrological and geochemical data collected in recent decades at Campi Flegrei with numerical simulations, and placed new constraints on the source(s) of the current dynamics of the volcano. The study helps in defining the best monitoring strategies and forecasting a future eruption.
