I May Have Detected Volcanic Tremor at LA PALMA- not El Hierro- Yes- at Mr. Mega Tsunami!

You may not always be right, but when it comes to the "doom porn" (I really hate that phrase), you're one of the few to be listened to as you generally base your ideas on science and known fact rather than rumour and paranoia.

Keep up the good work.

And here is a link to latest activity reporting

Ironically, I was watching Mega Disasters today (On Discovery Channel? National Geographic?). The show was about tsunamis. They say its not a matter of if the volcanoes in Canary Islands will cause a tsunami, but when. Thanks for keeping you eyes open TA!

I remember seeing a documentary on this a few years ago I think on NatGeo? It was wonderfully apocalyptic, even included a nice little animation of either florida or new york being hit by a mega-tsunami. One of the first documentaries I watched when I was younger, hooked from then on.

I wonder......looking on google maps.....I see an circulair seabed .....madeira on north and canaria on south....
could the aeria be an agient impact zone of 520km across with the islands on the rim's...?

That's funny, and not one single WORD about what I am reporting in this thread. I dunno, it's possible no one else has caught it... But, that is extremely unlikely. Scientists are too darn smart these days, and have too many accurate tools NOT to see it.

Seismicity, and even tremor, is not necessarily indicative of an eruption. Happens all the time at many volcanoes all over the world. But once tremor starts, it usually raises some eyebrows, and initiates further checking, and often further testing, for ground deformation and increased gas emissions, as well as thermal signatures, hydrothermal tests, and more. More? Yeah. Magnetic anomalies, for example. So there is lots that can be done, and the IGN has an extensive website, with all kinds of stuff like that. I've been poking around to try and find out more. But the focus right now is on El Hierro seismicity.

So yeah, anyone want to try and help, then poke around their site and see what you can come up with regarding any of the above mentioned other symptoms. If this is tremor at La Palma, which I believe it is, it still is not so strong and persistent that I am all that really worried about anything imminent. And also, I can't say that I've seen any recent seismicity that usually accompanies such tremor- although I stress that could be easily hidden in what is perceived to be El Hierro seismicity- unless you had access to the raw data and were looking at zoomed in waveforms where you can see the separation of P&S waves more clearly. El Hierro is so close to make that distinction, you would really need the raw data. And I don't have access to that. Scientists would though.

Since tremor usually indicates some kind of fluid or gas movement, these events could be indicative of a deep intrusion, under or near La Palma, and the addition of more magma/gas. Could be it is related somehow to what's going on at El Hierro.

That is some distance for the waves to travel, it must be a lot of rock that falls to cause that. Do you know which countries could be affected?

Or am I wrong about it being the Canary Islands?

From what ive read, the wave maintains momentum and may in fact get stronger, i may be wrong though. I wonder how much of an evacuation of the east coast could be achieved in eight hours? I wonder if theres an emergency procedure already in place for this exact scenario?
It looks like it would hit parts of europe and the UK. I thought spain would block it from reaching the UK, but from the reconstruction maps ive seen, thats no so. I live on the coast, gulp.

I'm not overly worried as long as I get a few hours notice, then it's to the top of Scafell Pike I go, only a 30 minute drive there, then a couple of hours to get high enough.......

Kind of ironic that an extinct super volcano may be the saviour (for some) from a tsunami caused by a volcano......

I would imagine THOUSANDS of other people will have the same idea. Have a nice drive ! You think road rage is bad now...

The beauty of living right at its doorstep will give me an advantage, that plus I have climbed it numerous times, I know all the roads in and the best track to the summit.

better sleep with one eye open and an ear to the ground



good luck

Maybe this explains the strange tsunami warning put out by NOAA for the EAST coast last year:

NOAA East Coast US tsunami warning video

You would think NOAA would be more concerned with tsunami threats to the west coast with the myriad of subduction zones in the Pacific any of which could produce a large west coast tsunami and many have done so in the past, where in the Atlantic no such threat exists. The only potential threats in the Atlantic are the Canary Islands and possible asteriod/meteor splashdowns, and for the more open minded PS's.

Both the claim that a catastrophic collapse would occur at La Palma and that such a collapse would create an Atlantic-wide tsunami are a topic of debate.

That reporting is for el Hierro not La Palma...but a good link to store as no doubt La Palma will appear there...if they have time to post anything before the tsunami hits!

You mean sleep with a snorkel and armbands on?

It's one of those things where the warning would get out, and everybody who knows everybody will be phoning everybody else to warn them.......I guess the phone system could crash....but then we have ATS

For comparison, here's actual harmonic tremors recorded at Redoubt (Alaska) just before an eruption...

So if you ever see the frequency start ramping up like that, yell. I also found this page (from following the link in your OP), showing the live (or historical) spectral analysis for Cumbre Vieja. I can only see very very slight traces of HT, at around 4 hz, but a touch of 8 Hz has appeared in just the past couple of hours. And there are seven tremors on it, too. You may be right...

As for why the "real scientists" are mum on the issue, never forget their primary concern: preventing public panic. Their biggest fear is issuing a warning for an event that doesn't actually happen, so they wait until the signs are very, very obvious and an event is very, very likely before any warnings are issued. I know for a fact that's how they think, at the USGS at least. The HT signals aren't big enough yet to make them start issuing warnings, but of course, by the time they ARE big enough, it's usually too late.

S&F for you.
OH S***

My youngest had a dream of BIg Ben's tower being felled by a tsunami of considerable proportions about 4 years ago.
The newspapers in the dream kept changing the dates, 2010/2011/2012/2013 as if there was a 4 year window for it to happen. Lots of other stuff happened too.

I'll keep my eyes on this.

That's it....., I'm leaving the planet.

Wonderful work! Have you noticed the Earthquake activity along the Atlantic Ridge, Spain, Tunisia and Italy? Possible link?
