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 rescuersBy 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.)

De Etna, de machtige vulkaan op Sicilië, trekt altijd duizenden nieuwsgierige toeristen. Bij de reeks uitbarstingen die zich nu voordoet, lijken die het wel heel bont te maken. Hun verkeerd geparkeerde auto's blokkeren de toegangswegen, waardoor de hulpdiensten hun werk niet kunnen doen.

Thousands of hikers climb Sicily's Mount Etna to witness eruption.

Mount Etna's first 2025 eruption has intensified, producing substantial lava flows and ash emissions which disrupted air traffic around Sicily on Monday.

Visitors from all over the world climbed Mount Etna over the weekend to get close to the mouth of the volcano and witness its latest eruption.

Je n’ai rien contre le tourisme sur les volcans actifs, à condition que ce soit fait correctement. Étant moi-même passionné par le phénomène, je comprends parfaitement la fascination qu’il peut engendrer. Malheureusement il y a de nombreux abus ; au fil des années, j’ai entendu pas mal d’histoires, allant du groupe qui entre sciemment dans la zone interdite du Krakatoa au tour operator banni de Hawaï pour non-respect des règles de sécurité…

Quand je vois ces images de la coulée de lave actuellement active sur l’#Etna : youtube.com/watch?v=5sRA3gf_2y
je pense tout de suite deux choses :
– C’est magnifique.
– Mais que font ces gens à quelques mètres d’une lave qui s’écoule sur de la neige ?!
Lave + neige = situation potentiellement explosive, et les guides de l’Etna le savent parfaitement, puisque ce cocktail a déjà explosé en 2017, faisant une dizaine de blessés : bbc.com/news/world-europe-3929
À croire que les guides n’ont rien retenu de cette cuisante leçon… J’espère au moins que leurs clients en quête de selfies savent à quoi ils s’exposent.
