Maybe it's the retard in me but if there was no danger of dying from falling into collapsed ground or monoxide poisoning or anything I would love to walk around there.

Makes sense to me, idk. Makes sense you'd like to walk around there if it's safe.

So what is the caldera collapses? Minor Tsunami and the east coast would get a few ripples in the water.

The Calcdera would have to entirely collapse allowing mountains of saltwater into an immense cavity to cause any kind of explosion worth a damn. The physics and size of this eruption just do not equate to that happening. There has to be a substantial chamber exposed for the fireworks we dream of.

Imagine you (assume 180) pounds are the Tambora 1815 Eruption and your weight equals the volume of material thrown out by that monster. La Palma to date has through out the amount equal to 2 tablespoons of water.

If you were the Tambora eruption 74ka ago, and your weight equaled that eruption, La Palma has thrown out 1/4 of a teaspoon.

I love doom and gloom (honestly) but the only scenario that even slightly bothers me is an impact event - simply because we do not have full monitoring of the sky and despite one thinking we see everything, the reality is I think only a few bolides have ever been detected BEFORE entering Earth's atmosphere - in other words we are likely going to get little warning at all and we right now have our pants down waiting to get caught.

And we just do not have the funds or willingness to develop a means to stop one of these large bolides from impacting; despite it being within 99% degree fo certainty as absolutely happening within a reasonable amount of time.

If we ver get words of a NEO with a degree of probability of impact I will certainly turn into a proper, no doubt about that.

You’re missing what the danger is with La Palma. It’s not an explosive event, it’s an earth movement. The island isn’t a normal volcanic cone. It’s more like a steep pillar rising up from the ocean bed. The danger is parts of the steep pillar are known to shear off. With a whole portion of the island falling into the sea. When this happens it can release enough energy to cause a tsunami.
 
Any idea when the eruptions will stop? Next couple of days? Weeks? Months?

Something has definitely happened since this morning... Looks nuts at the moment.

It was spewing lava like a geyser then a short time ago one of the sides fell in to the hole. Now it's the odd spurt with lost of lava. Pretty exciting. We may see a big pop.

Apparently 3.9 earthquake happened recently
 
I just wanted to say thanks to everyone updating this thread. It's really interesting, but I have nothing to add.

Wow, it's ANGRY about that collapse; was already so violent tonight and now you can actually see that the erupted material is being forced out at an angle because it's partially blocked on the collapsed side. Wonder if that means all the pressure will make for something else major, or if it'll manage to melt through that collapsed material.
 
There have been 28 earthquakes in the last 24 hours in the southern area where the magma source is probably located. If the caldera of this volcano is collapsing, we may see another big vent or volcano appear. There’s certainly no lack of magma, that’s for sure.

It's going off like the fountains at the Bellagio.

It looks like one major vent is spewing all of the shit, and there's a smaller vent that's like a bubbling lava spring, just trickling lava down the hill.

It looks like the wind is blowing all of the magma/lava to the left hand side of the volcano. It doesn't look evenly distributed, so if that slides back in and blocks the hole again, we could see some real fireworks. At a guess. I'm not an expert.

I don't know what's going on but the past few minutes have been absolutely mental
 
Sorry to keep spamming the thread but this is immense

Contant lava jets. 3.7M earthquake @ 10km, apparently a 4.7 was recorded

Lava is pissing down the mountain

Hard to see on a still, but there are some massive chunks of lava rolling down this hill

Last picture for now. Vent has really opened up. Left hand side of the cone could collapse. Lava river forming.

wow much change, such lava. Looks like a different volcano from a few hours ago.

I met a guy in a pub a few years back, and before I spotted his Post Office satchel (he was a postie), he told me he used to design/build nuclear powerstations. Ok, I thought, quick test, what's a neutrino? What is the half-life of U-235? He passed without a fluster. He might still have been BS'ing, but seeing as he had quite a few friends with him (who were all at the bar/toilet) I reckoned it wouldn't be long until his little game was up. But no, he really did used to build/design nuclear powerstations.

I asked him if he missed it, and he looked a bit wistful for a moment there as he looked in to the distance and said that he regretted giving it all up on a point of principle, because he should have stayed, to make the nuclear power stations safer, which they wouldn't be now, with him gone, and the bastards in charge not caring so much about safety.

So we got on to the subject of safety of nuclear power stations. And he made a very salient point, and one I've heard time and time again since from people in various fields when it comes to this subject: No one wants to put any safety measures in place, because politically, it means that things might go wrong, questions might need to be answered. So you lie, you say it's safe. Of course nothing could ever go wrong. And this breeds the kind of culture where yes men and career advancers take precedence over those that might have a firmer foot in reality and want to make contingencies for very worst case scenarios. Chernobyl is a perfect example of this mindset if you want to know how such a catastrophy could happen.

Now, the reason I'm sperging out over this is because we have a very similar situation here. I live in a part of the world that would be effected by the Tsunami should the worst case scenario kick off. But there are no contingency plans. Nothing. I don't think anyone knows what is going to happen, but even if it were a fraction of the worst case scenario, we would still not be prepared here in Bongland.

And if the very worst were to happen, of course, no contingency plan could ever really make up for that; better hope they drop the H-Bomb on your head than at 5 miles out; better hope that big wave engulfs you and drowns you quick, smashes your head against your living space/tree trunk, than be one of the poor suckers who has to pick up the pieces 30 miles out when the zombies come looking for food, kind of thing.

If this slice of rock were to plunge in to the ocean, it would hit us before the East coast of US. Some say it would be amplified as well by the shape of the channel it would be coursing through. I can believe that. We have a thing here called the Severn Bore -


It's like a funnel that picks up speed and height due to the shape of the underlying geography. You get the picture. Now, I may be wrong, but it's plausible at least that this would not be such an insignificant event, should the shit hit the fan.

But just as there are no safety measures in place for people who live around nuclear reactors (they would get too spooked otherwise and start causing a fuss), there is no warning system for any kind of Tsunami event, that I am aware of anyway, in place to give people a quick heads up.

The shore line around here is very steep. You don't go swimming in the water on the coast here. It drops off super sharp just a metre or two out. That means the wave would gain height, or so I believe to my meagre understanding. It kind of makes sense. It hits a de facto wall, so just splashes up. It's got inertia - it's not going to stop traveling - it just changes shape and carries through that kinetic energy in another form, be it height or wtf.

The Post Man who used to build nuclear reactors told me that a true meltdown is a very rare event, but it's still possible for all kinds of fuck-ups to happen that can actually be mitigated against to a certain extent, should they just be accepted and accounted for. Spikes in radiation, make sure the local populace has a ready supply of Iodine pills. Sure, past a certain point that don't mean shit, but up to a certain point it's a viable and doable safety measure that doesn't really cost very much to implement. He was just proving a point. I think you will find, that even to this day, there is no mention of or greater supply of Iodine pills around the local areas where nuclear reactors are situated.

It's called the Ostrich plan: just bury your head in the sand and hope and pray it never happens.

And apart from all that, though we can't contain mother nature, and we can't even really plan for very worst case scenarios, there is a lot we can do for the aftermath of such events. Look at Katrina. What a fucking shit show that was. Caught with the panties down on that one. No one held accountable, even those responsible at the time. Carnage. Same kind of thing. Could have been planned for, but no, the fuckers in charge took the money, lived high off the fat of the land, and shirked off when motherfuckers had to end up shooting each other to survive, because law and order broke down, mob rule ensued, and people really had no other choice.

You can never stop the big things happening. But man is not a totally stupid beast. Though he is somewhat ignorant it would seem. Make contingency plans for the aftermath of such events. Be it Hurricane, Tornado, Tsunami, Meteor impact. It's probably no more than a sticking plaster on a gaping wound. But at least we could say we did our best. That we tried.

So far, there is no planning at all for any super catastrophic event like this. It would cost too much. Read: it would siphon off money from gibs already being siphoned off elsewhere and would have to go somewhere where it mattered. Oh no!

It would take too much effort and not be a realistic endeavour. Read: I might actually have to do some actual fucking work for once. Oh no!

We've seen where the priorities lie with these fuckers in power. They'd rather half the population die of cancer because of lack of testing and treatment, just so they can carry on their little charade with the WuFlu and make a profit. Well at least they didn't die of the coof!

I'm not worried about Tsunamis. Not worried about nuclear meltdowns.

But I am worried about the people who pretend to be in power knowing best and having our best interests at heart. They aren't even trying. They aren't even pretending.

Just as we are seeing with the knock on effects of chinks in the chain of the supply loop, it would be the aftermath and the end-products of a catastrophic event that would touch us all in one way or another, days, weeks, months, even years after the event.

Read up on those really big volcanic eruptions. Summer canceled. Crops failed. Famine ensues.

But I'm sure the really big players have their bunkers in NZ. With a 5 year stack of refrigerated foods and even seeds to grow new crops. They are that bond villain evil, I would believe it. And we will be the zombies, plucking each others eyes out for a tin of baked beans.

Sweet dreams.
