It's amazing to have the technology to watch it in real time, to go back hours to watch certain events, and to do so from the safety and comfort of our homes. I bet the islanders are exhausted from worry and stress, ash and earthquakes and the uncertainty of their future. Prayers for them all.

Caldera collapse
Significance
Earthquake physics require understanding how the frictional resistance on faults varies leading up to and during seismic slip. Laboratory rock friction experiments have led to widely used friction laws that depend on sliding rate and slip history. However, these experiments are restricted to samples vastly smaller than natural faults. Highly repeatable, and exceptionally well instrumented, caldera collapse events at Kīlauea volcano can be treated as kilometer-scale rock friction experiments and entirely validate laboratory experiments. Caldera collapse is caused by rapid draining of magma from a shallow crustal reservoir. Collapse transfers weight to the underlying magma reservoir, thereby sustaining the eruption. Our results permit more accurate understanding of conditions leading to caldera collapse and high-rate basaltic eruptions.

La Palma happenings: Officials just admitted VEI 3 & potential Plinian eruption which means it is actually 4. A full Plinian means next stage is Caldera Collapse.

Just a lot of people posting old stuff, or exaggerated hugely distorted stuff or totally made up stuff on the internet lately and today seems like a lot has been posted to tb2k.

The actual livestreams are linked multiple times on tb2k for anyone to watch or look at.
Timestamped and everything so it can be rolled back to look at specific times for comparison, like when the big quake hit earlier. That was cool to watch.

Ask yourself why someone (not meaning daniel boone, just the people that have been posting them to the internet) has to post shaky, partial images of their computer screen when they could link the live video or a short clip a whole lot easier. And why are so many people posting Hal Turner? He takes a grain of truth and twists it into being a skyscraper in the process of tumbling down.

I am cranky today and it just seems like a lot of crazies are roaming free today.

Plus, the "NO" was in reply to the "Is this IT?" at the bottom of the pic of the volcano.

NO, it is not the start of a massive final lava event leading to caldera collapse.

It is very possible it could end up collapsing.
I had posted weeks ago the Spanish professor's concerns, but it is not happening right this minute or hour or even today like some seem to be hoping for.

This island already has one collapsed caldera, from thousands and thousands of years ago. (over 100k I think, have to look it up. ETA: caldera over 500k years ago). That is the big tear shaped gouge in the top one third of the island on the North West side.

So, it very well could happen again.

Caldera collapse: In a nutshell, multiple vents on the lower side of the volcano can partially empty the topmost magma chamber, leaving the walls of the volcano with nothing under them. When they collapse inward, it's kind of like squeezing a plastic water bottle, and the lava can shoot out explosively.

There are other things that can happen, namely, seawater getting into the chamber and creating an explosive situation that blows the side of the volcano out.

Lots of ways it could happen. Look at Mount St. Helens -- if all that earth had gone into a body of water, there would've been further problems.

That isn't to say it will happen, but there's certainly the possibility. I won't go to probability at this point because I don't think there's a high chance of it happening, so... possibility.

18 cm is a little over 7 inches. (2.54 cm = 1 inch)
Mt St Helens bulge was 450 ft
LP3 is a road.

OOOooh... OOooh...

18 cm...

WOW all of 7 inches...

EDIT===>

Come on back when the lifts has grown enough to lift WWII ships out of the water...

DAMN CG I stopped listening to that ijit, before he got to the bulge comment.
I mean I quit when he said they were trying to hide the truth, and when he said they might be creating the EQ tremors.
Gotta agree with Nana on this one.

What I want to know is why, if there are so many 2.5-plus earthquakes associated with this (4.5 and 4.2 from the above post, for example), the USGS site hasn't shown a single event for the Canary Islands? Unless, of course, it's a conspiracy ...

I think you are on to something i went to this site Earthquakes Today: latest earthquakes worldwide during the past 7 days - list, stats and interactive map
and zoomed in on La Palma and this is what it shows for the last 7 days.

There's an explanation several pages back.

oh my gosh
they have had 253 quakes in last 24 hours, 252 of them have been 2.0 or higher, 99 have been 3.0 or higher and 1 has been a 4.0.

nuts. Easily twice as many quakes in a 24 hr period over the last 30 days.
scroll down for graphs of daily, hourly and 30 day EQ volume.

Earlier up thread someone said that Bushcraft Bears wife left him because of his reporting on the volcano. Nope, she left the island because she couldn't deal with the sounds of the volcano anymore. Huge difference if you ask me, but alas you did not ask me.

I'm glad she just evacuated and didn't leave him. That thing sounds like jet engines running 24/7

Well, the main one we have always watched (multiple vents) has gone dark, only a little flicker, but lava still coming out from the bottom.

The other vent that had opened up, is still spewing.
can see it on the bottom link in post 1064
