La costa lavica etnea, dai canyon sottomarini all’isola Ferdinandea

C’è uno scivolamento di tutto il versante orientale etneo verso il mare, che si realizza all’interno di un settore crostale che ha come binari il canyon di Fiumefreddo (a nord) e quello di Catania (a sud). Anche di questo si è parlato nell’incontro, “Geologia della porzione sommersa della costa lavica etnea”, promosso dalla Lega Navale Italiana di Catania (LNI), diretta da Salvatore […]

My partner and I have volunteered for mountan rescue in Cumbria and the Highlands for more than 30 years and multiple call outs - but heat has only been a problem.a couple of times - in the summer and a retrieval of dehydrated walkers. This is a little different.

Having said that, high heels on Striding Edge (really!!!) was a novelty

Good luck to all and please sheeple, read the news!

The Guardian · High heels and risky selfies: Etna eruptions cause despair among mountain rescuersPar Lorenzo Tondo

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.)
