Potential Disaster in the Making 10

[phamENG]

Cumbre Vieja, a volcano on La Palma in the Canaries, just erupted a couple of hours ago. National Geographic did an episode on it as part of a 'Disaster Earth' series a few years ago. Essentially, there's evidence of a massive landslide on the island a few hundred millennia ago, the likes of which would have formed a tsunami large enough to hit the east coast of the US. A recent earthquake seems to have restarted the process and formed a large fissure along the island.

Here's to hoping it doesn't move any more....

it might be coming your way

...about 800m to the 'big lake'... then see what happens; I don't know how much or how many gasses there are in volcanic flow, but I suspect there can be a couple. I also don't have a clue about the interaction of lava with sea water... there could also be some 'surprises'.

thanks, Alistair...

big explosion depending on temp of it. If its hot enough you start making O2 and H2 in rather large quantities.

And there are loads of gases not many of them are pleasant. And get even less pleasant when water is involved.

Found a bit more on the worst case tsunami scenario. It seems that the US east coast doesn't have to worry about any tsunami over .. 10–25 m ft =(3–8 m) in height. 500 km[sup]3[/sup] is one hell-of-a-lot of material.

the Icelandic guys were saying its the acid vapour which is the big problem with it going into water.

It will strip paint in seconds.

Thanks... hydrogen chloride, I would suspect and others... and react with lung mucous, etc.

There is loads of sulphur as well

 

[dik]

Sulphuric acid is not as volatile... mind you, you cold get sulphur dioxide, etc... which is pretty pungent. It could get really unpleasant.

To be honest I though water would have need to get over 2000 Deg C and lava was about 1000 C

But when it comes to volcanoes and hunting whales I will take the Icelandic's word for it.

 

[1503-44]

They expect the nearby surface water bulk to heat +20C. It's around 24 today.

Boiling currents may cause undercutting and cliff erosion.

There were more 3.x earthquakes occurring at the 12km depth to the south at 1800 UTC.
More lava percolating up???


Since the islands span over a distance of 500km, most other things are pretty normal.
I'll bet a lot of you don't know that we play baseball here. Puerto la Cruz won the playoff.

The lava is really picking up speed.

No doubt about it... I can see acid being produced and causing major corrosion issues... just think HCL rather than H2SO4...

Authorities have prohibited unauthorized drone flying.

Typical govmt short-sited heavy-handed imbecilic BS. There are no planes allowed so why would they care about drones. Drone forte is getting into hazardous locations for high def results. Drones could map the flows easily, quickly, and hourly. They could also provide up-close details of how the lava is physically moving and changing.

I'd invite drones to have-at-it as long as all data was provided to a clearing house for officials and volcanologists.

Looks like its staying in a good direction.

"chlorine, sulphur, carbon and hydrogen sulphide, hydrochloric acids, carbonic acids, CO2 will be formed"

That's from one of the Icelandic's who's brother is a volcanologist in Iceland.

Anyway to be honest I agree with you..... more interested than anything else. As the Icelandic said its worse than a Russian mother in laws Fart. Which got him elevated to sage levels of knowledge transfer in the crew room in my book as pretty much everyone grasped the toxicity level.

 

[RedSnake]

Russian mother in-laws ..
They write that the lava has reached the sea now..

Right. Its reached the ocean now, via a south route around 3 Peak Mountain. Have to see what the dawn brings. Sun just coming up.
There is a large cloud bank holding just offshore here, so I see nothing.
Winds have been rather strong from the east since yesterday afternoon, so any toxic clouds are all going to Brazil.

Yesterday 0708 UTC

Only private, unauthorized drones have been prohibited. The gov INVOLCAN, IGME, Cabildo LaPalma agencies are flying. There have been too many UTube and tictokers out with their toys. Bushcraft Bear should stick to the Alps. He's taking up hotel room. First post he was going to find out the exact location of the volcano. Result: "Can't see in all that smoke. Its somewhere over there."

 

[RedSnake]

Yes and talking about the smoke it's a bit fascinating that the color of the smoke can be so different even when the craters are so close to each other.
