Prepping for "VOLCANIC ERUPTIONS".

[Sourdough]

I suspect this is a NONE issue for most on this forum. I have experienced several in the last 55 years in Alaska. And one quasi-local one is developing a cranky attitude.

As far as preps are concerned.......don't operate machinery (cars/trucks/snow machines/etc.) Especially don't use windshield wipers or rub volcanic ash off your vehicles. Have good masks. Most stop erupting in 6 to 10 days. You could be trapped in some locations, as aviation comes to a 100 % STOP.

In Alaska it is not just our local volcanos, we get some international volcanic ash. Especially from Russian volcano eruptions. Generally damaged vehicle windshields are the typical problem.

I once had the great pleasure of being trapped in Hawaii for eight days, with all hotel and meals paid by the airline, because of Mount Spurr (Alaska) erupting on my return leg from New Zealand.

I still have tub of ash from mt st helens. If one isn't in the way of a lava flow breathing protection and the ability to hunker down and stay put is probably best.
We have a friend that was in the way of some lava flows in Hawaii.....their house is no more.

I'm just waiting for Yellowstone to blow.

Yellowstone would be the only volcano that would give me any concern, and if that blows, well, it's been nice knowin' ya.

It should be, few places are really completely safe from this.

Correct.

While the majority of volcanism occurs at/adjacent to tectonic plate boundaries (and particularly as "Island Arcs" through oceanic crust), some volcanism is associated with "hotspots" in the upper mantle.....and can occur virtually any where (and indeed far from a plate boundary).

The Hawaiian Island chain and all their volcanoes, are the result of a single hotspot in the upper mantle.

Hawaii is almost smack bang in the middle of the upper half of the Pacific plate.

Interestingly, the hotspot is stationary and the chain of islands has been created by the progress/movement of the plate over the hotspot.

As a kid I lived at Mammoth Mtn. The long valley cauldera was right there. In fact that's how the mtn was formed. It blew up like St.Helens. We had hot springs and sulphur springs all over. I nearly drove into one in my truck once. On a dirt road, I found a nice flat area to turn around. As I started to turn I noticed steam coming up through the "dirt" ahead. But it wasn't dirt, it was a hot spring with a thick layer of dust and leaves on it. That would have been a warm bath...

There was a section of the San Andreas fault you could climb down about 30 ft into, also. It's all touristed now with railings and info plaques. Anyway all those multi-million dollar ski chalets may be toast if it ever goes up.

Devils Postpile is nearby as well as a place called Obsidian Mountain. As a kid we could collect really shiny obsidian. I still have a couple of chunks. We went there last summer, but it's been totally picked over. I bet a truckload of C4 would probably open up some good ground.

Well, I guess I am too!!

 

[Patchouli]

With the way "they" have learned to manipulate the weather perhaps the volcanic eruption ash wouldn't come this way, @Pearl
Head south. I watched a pretend documentary movie at least 15 years ago on this very topic. It was Yellowstone. Parts of Texas were safe but a lot of people went into Mexico to escape.

I have masks, Tyvek coveralls, and permanent air filters for each vehicle. Otherwise it is the same preps as any other disaster. Actually the masks and coveralls are good for nuclear and other disasters.

That and even from known sources, can have serious effects for hundreds if not thousands of miles away.

Volcanic events also have a lot of overlap with nuclear and meteoric events so there is significant crossover.

If Yellowstone goes everyone will be affected, although Volcanoes are not at the top of our bingo card. Earthquake maybe, further south, that might effect family members.
A few years ago the Icelandic eruption caused havoc with flights etc over here. The winds didn't blow this way, so ash was not a problem luckily.
There is a volcano in the Canary Islands that is due to erupt, and scientists say it will collapse causing a tsunami that will reach here and the US east coast. Ireland is bowl shaped, I can't imagine it reaching us, but as a small Ireland, there really is no where to go - there are some mountains north of us, but I don't expect help from anywhere. Que sera,sera.

When Las Palmas goes up the tsunami could start out as much as a mile high. About a third of the island will fall into the ocean creating the largest known tsunami ever. It will wipe out the East Coast, Gulf Coast, Caribbean and then it will bounce back and hit Europe and Great Britain. The South Atlantic won’t do any better. The entire Atlantic will have tsunamis bouncing around like the bowl of Jello that Grandma dropped on the table. It will go hundreds of miles up the Mississippi and other rivers. Before the first wave can empty out of the rivers the second wave will push the first wave back up the river. The third wave will repeat the process. If you are near any Atlantic Coast, or a river that dumps into the Atlantic, be ready for a flood.

Alaska had a tsunami in Latuya Bay that was measured at 1720’. The Canary Islands tsunami will make Lituya Bay look like a pimple on Grandma’s ass.

That would be the Cumbre Vieja on the island of La Palma, and it does erupt. Last time was in 2021, and the eruption lasted for 85 days. I was watching it very closely since our daughter and family live on the East Coast. I think of that volcano much like the San Andreas fault. Everybody seems to be waiting for "The Big One".

If Cumbre Vieja blows the island will break in half and cause a massive tsumani that will reach the East coast of North America and much of Europe. This is one simulation. The early part of the video is a history of the island. The simulation comes in at about the 3:00 minute mark.

Appharently the Canary island thing was debunked. I guess it all comes from a 2001 history channel fluffy piece that got re-shared and turning into 'a thing'.

I’ve been to La Palma Is. There is a big crack that runs through much of the island. In my estimation, an earthquake, probably caused by an eruption, could cause a major portion of the island to slide into the ocean.

If I remember, it wasn't that it couldn't break off, it was that the actually wave would only be about 3 feet by the time it reached the coast.

Predictions are guesses, nothing else...
Take the tidal surge 'predicted' for the landfall of hurricane Milton of 12-13 feet.

Sounds pretty accurate.... within a foot, right?

Actual? 1.2 feet.
Nobody ever gets called in on the carpet for this BS.
Polar ice caps completely melted by 2014?

Perhaps. Earthquake caused tsunamis are limited to about 30’. Landslide generated tsunami’s have no such limit. The Good Friday Earthquake in Alaska generated a tsunami that killed people as far south as CA. There was an earthquake along the Cascadian Fault that killed people in Japan. Both were larger than 3’ when they arrived and the Pacific is much larger than the Atlantic. The Canary Is. tsunami will start out much larger than the Good Friday tsunami. Remember the Latuya Tsunami reached 1720’ and it was caused by a landslide much smaller than the Canary Is.slide is expected to be. You couldn’t pay me to live in Florida. I don’t know how big it will be and anyone that tells me how big it will be, I ask if they wanted to sell me a bridge.

no volcano's in the UK although there was an issue when the Icelandic volcano erupted some years ago, it affected air travel for a while which didnt affect me as I havent flown anywhere since 1977.
