Volcanic ash rains down on Bariloche

I lived in Bariloche for 3 years. During that time, another Chilean volcano blew and affected air travel. This one is more serious as the ash and sand is everywhere.
 
This is a big volcano, there were great skiing lines inside that crater. A girl that climb the Villarica volcano in Pucon with me skied inside it. She was showing me the pics. A hell of an expedition. This volcano is massive, I took a few pictures of it while I have crossing back in between Villa La Angostura and Osorno.

Great vid that give you an ideal of the size.

The Chaiten eruption happened the previous time I was in Patagonia in 2008. You could see the ash cloud from the top of La Hoya. Not a specialist on SA, but the size and location was more remote (for the ashes). I know that Esquel would get some ashes from that eruption, but there isn't that many people around Esquel.
 
The hard part of this event is that it would be difficult to get in and out of the area because some flights were canceled due to ash falls-aircraft's zero visibility.

I think the reason is that the ash is abrasive and can damage the jet engines. Although, at least one Eurpoean carrier performed some test flights in Iceland with apparently no damage.

The danger is that the ash doesn't just abrade the engines but it causes compressor stalls and subsequent flameouts. Props can easily fly through ash but with Jets it's incredibly dangerous. There was a famous British air 747 known as the Gimli Glider that lost over 20,000 feet of altitude before it was able to get the jets to power back up. Had the ash cloud gone down to the ground that 747 surely would've crashed.
