L:a Palma is livening up with tremors: https://www.mirror.co.uk/news/world-news/popular-spanish-holiday-destination-risks-24980862

The authorities in Canary Islands are likely to downplay the risks, too much tourist income at stake. La Palma is also a huge tsunami risk to Atlantic shore-lines. Peter

La Palma, Cumbre Vieja eruption, background geology in the article, ongoing stream of posts give updated photos etc

This is the island  that, were its western flank to slide into the ocean, would possibly create a mega-tsunami across the Atlantic.

The area around the eqs has risen ca 16 cm.

Estimated volume of magma injected 50 million cubic meters. From Volcanocafe commenter:

From RUV.is. Translated using Google.

If there is an eruption in the area between Fagradalsfjall and Keilis, it could be more powerful than last year’s eruption at Fagradalsfjall. This is what geophysicist Freysteinn Sigmundsson says. The flow of magma corresponds to ten times the flow of Elliða River. Lava could manage to flow to the north from the place that is considered most likely to erupt now.

“It is most likely that it will be over this magma tunnel that is forming in the earth’s crust. And it actually extends from the eruption stations from last year and three kilometers in the direction of Keili, so that area is the most likely,” says Freysteinn.

Freysteinn says that it is likely that an eruption at this location can reach Reykjanesbraut. However, it is not at all certain that it will erupt in the next few days. The reason for this warning by scientists now is this huge influx. “There is a higher inflow rate and that is the reason for this warning.” This corresponds to about 50 million cubic meters, which is the most likely figure that comes from model calculations by the scientists of the Icelandic Meteorological Office. It is ten times the average flow of Elliða River for comparison. But it is flowing into the earth’s crust and because the flow is greater, there could be more force in this eruption, but the nature of the eruption would most likely be the same, a lava eruption with craters and that the flow would be limited to certain craters, but there could be more coming up from them and then more gas could come out and possibly a little bit of pyroxene”, says Freysteinn.

Volcanocafe has a new thread on the eruption;

https://www.volcanocafe.org/fagradalsfjall-eruption-2/

Albert is a prof of planetary geology at Manchester.The Comments are by a mixture of enthusiasts and professional  volcanologists,Iceland being Mecca for their research.

Your link to close up camera with sound doesn't work for me.  This does, from Twitter, via the volcanocafe site.

But here, our intrepid reporter gets REALLY up close to the eruption!

Tks John. On Volcano cafe there was a news item saying 10,000 were visiting the site. I guess mostly locals, as the population of Reykjavik, 200,000,is only 30 miles away !  Kevlavik airport is also close...if only I  were younger I'd be taking a flight. Peter

Go for, it, Peter!    You're only here once!

You're fascinated by eruptions - have  you ever seen one as up close as that?

If my legs worked I would, John. But the PD and I suspect sarcopenia defeats my ambition.

B*gg*r!

The up-side is I "discovered" D3 well before C-19. My sporadic PD is likely a disease of D3  deficiency and brain inflammation. It is absent in rural Kenya, where 25(OH)D is ca 100-150 nmol/L - my target. In Niarobi 25(OH)D has fallen to 70nmol/L and sPD about half UK rates.....  I join up the dots ( and a lot of other mechanistic stuff) and suspect the one in 50 cases in UK men at age 80 could be avoided.

Eruption looks to be starting: https://livefromiceland.is/webcams/eruption2307_2

I'ii try to find a better webcam. I follow 'recent comments' on the right side of the Volcanocafe blog. https://www.volcanocafe.org/

It is where several Icelandic volcanologists contribute.'Albert' is a prof of planetary geology at Manchester univ.

New thread on VCafe, by Albert: https://www.volcanocafe.org/fagradalsfjall-season-3/comment-page-1/#comment-129806

the best place on the web that I know for keeping up to date.

The eruption site is about 25 km from Reyjavik and from the international airport at Kevlavik.
