[Un zeste de lumière ... et de chaleur 🌞] Le 30 septembre dernier, l'imageur ultraviolet de la sonde #SolarOrbiter de l' European Space Agency - ESA a pour la première fois capturé une #éruption solaire : l'énergie stockée dans les boucles de champ magnétique a soudainement été libérée, élevant la température de la #matière environnante à plusieurs millions de degrés et générant des #radiations sur l'ensemble du spectre électromagnétique - depuis les ondes radio jusqu'aux rayons gamma.

Cette éruption de classe M (moyenne) a atteint la haute atmosphère terrestre, perturbant les communications radio au niveau des régions polaires : esa.int/ESA_Multimedia/Videos/

Fagradalsfjall Volcanic Eruption Before Sunrise, Iceland

The Fagradalsfjall volcanic eruption, which began in March 2021, marked a significant geological event on the Reykjanes Peninsula in Iceland. This eruption was notable for its relatively gentle effusive activity, characterized by the emission of lava flows rather than explosive volcanic eruptions. The eruption site, located near the Fagradalsfjall mountain, attracted considerable attention from scientists and tourists alike due to its accessibility and the stunning visual displays of flowing lava.
The eruption was preceded by a series of earthquakes, signaling the movement of magma beneath the surface. This seismic activity is common in Iceland, which sits on the Mid-Atlantic Ridge, a tectonic boundary where the North American and Eurasian plates are diverging. The eruption itself produced impressive lava fountains and created vast fields of basaltic lava, reshaping the landscape.
Over the course of several months, the eruption underwent various phases, with periods of intensified activity and quieter times.

I'm going to take advantage of the current #eruption on Mt #Etna to discuss some of the challenges of #modelling #lava flows. Buckle up (or just silence me) because this is going to be a long thread.

First of all, why do we want to model lava flows? The answer most definitely isn't «because we can», since —as I'm going to explain momentarily— we actually cannot. Still having an idea about how lava flows and sets in place is a powerful tool for the assessment (and possibly mitigation) of the associated #hazard and #risk: if we can tell how lava flows, we can tell which areas are going to be reached by the lava, and hopefully also improve the design of tactical and strategic actions that can be taken to minimize the damage.

(Of course, whether or not those actions will then be taken is an entirely different matter, but that's mostly politics, not science.)

"Researchers from Tokyo Metropolitan University have carried out an unprecedentedly detailed survey of pumice rafts in the aftermath of the 2021 Fukutoku-Oka-no-Ba volcanic eruption in Japan. Using samples from 213 different locations, they considered raft density, the size and roundness of individual pumice, and biological species attached".
