I remember when Mount Unpronounceable in Iceland erupted and closed most of European airspace.

SWMBO, I, SWMBO's sister and her husband were stuck in La Palma for three extra days. Full board and lodging in a 4* hotel at someone else's expense. Dreadful ordeal.

Canary Islands, I would guess. Tenerife was where two Boeing 747's collided on a runway covered in fog. It's still on the books as the worst airline crash ever. IIRC, nearly 600 died. Less than 100 survived.

No need to guess. Where else might you find La Palma in European air space? Note: unadorned La Palma, not La Palma del Condado or La Palma de Cervelló. I suppose if you wished you could push your luck and go for an obscure district in Malaga.

I tried to be specific because there is a La Palma, California. Many in the U.S. would make the same association. I knew of it because it was mentioned in a documentary about the Tenerife accident which I had seen.

Here is live camera of the volcano eruption here in Iceland https://www.ruv.is/frett/2021/03/20/...a-eldstodvunum

Small eruption. But The saga say it was before year 900 since known eruption have been in this area and last to year 1241 with pause. So question is if the saga repeat itself again.

News reports say that the Fagradals Mountain volcano has been dormant for 6000 years.

I tried to track down how that determination was actually made, but without success. Apparently this particular volcano creates lava flows, without much ash.

I was able to imagine some possibilities. One was, by observing how the rock from lava flows has weathered. Another is, if a lava flow happened to have covered living plants, there might be some charcoal that could be carbon-dated. If some of a lava flow had been subject to regular sedimentary deposits, it would be possible to say how long that had been occurring.

There may be radioactive dating methods other than carbon dating that would apply, but 6000 years is pretty recent for the ones I'm familiar with to be accurate.

Anybody here know? Thanks!
