Sometimes you see a #nature photo and you suddenly understand where the #myths came from

No #eclipse here. Sun set before the moon had the time to cover it, it was cloudy anyway, and when it didn't rain rain, it rained volcanic ash.

I've mentioned in the past that among other things, we rely on the #Meteosat geostationary satellites to monitor #MtEtna. Even though the spatial resolution is low (the sub-satellite pixel has a nominal resolution of 3km), these satellites provide information at a high temporal rate: MSG (Meteosat Second Generation) provides full-disk images are available every 15 minutes, and a RSS (Rapid Scan Service) that only covers Europe, with data available every 5 minutes. The RSS satellite is also located at 9° of longitude east, so there is less distortion on the Etna (~15° longitude).
The main downside of RSS is that the service is not continuous: every 26 days, the satellite goes into “Full Earth Scan” mode for two days: this is needed to keep the mechanisms in good working order, and the data from these scans is NOT made available, which means that every 26 days there's a 2-day hole in the RSS data.
And obviously this happens during an ongoing #eruption. Murphy's law strikes again!

Come giustamente ha detto la mia collega nella nostra chat di lavoro, «Ma sempre a #Ferragosto?»

People don't believe me when I say that volcanoes only erupt during vacations.
So anyway. Guess what me and my colleagues are doing right now.

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.)

A selection of some of the photos I took on our expedition up the active volcano, Mt. Etna in Sicily last week.

Enceladus was a fire-breathing giant from Greek mythology who battled Athena during the Gigantomachy. He was ultimately defeated and buried under Mount Etna, where the imprisoned giant's fiery breath is said to be the cause of the mountain's volcanic activity. #MythologyMonday

#TIL volcanoes can puff out “smoke rings” - although the rings are not actually smoke, but rather water vapor. The phenomena is something akin to contrails. Mesemerizing!

Lava fountains are spectacular, but most of the lava falls back into the crater or spatters just a bit around it. During the activity you still get some overflows, that typically cover one or two kilometers.

Here we go again …

Who has two thumbs and will probably spend the extended mid-August weekend doing volcano monitoring because #MtEtna decided to wake up?

#thursday #dinner Bucatini Frutti Di Mare with capers, anchovies, fresh parsley & basil. Served with mixed greens, cucumber, mixed tomatoes, Kalamata olives & shredded Reggiano with a balsamic vinaigrette.
#wine pairing is a #singlevineyard #oldvines #NerelloMascalese from the north side of #mtetna offering very Pinot-like elegant raspberry, grilled plum, dried orange rind, smoke, leather & minerally charcoal notes.

Hiking on a #cinderCone I could hear the mountain "breathe" - distinct low booms every minute or so, as if hungry. The landscape there is eerie black with #birch #tree forests in stark contrast. I stayed late in the evening for a light show of lava and hot boulders.
