Best El Hierro Thread On GLP - Canary Islands - ACTIVITY HAS RETURNED - AGAIN!

3.7 north of la palma apparently..

Thread: Breaking !!! Earthquake Just North of La Palma

I've been under a week long IP wide ban by Trinity. Freakin BS. I finally gave in and bought the subscription...again.

This...at 79km deep is what will wake this monster. It seems either the archipelago is angry or we're finally seeing reactions to the tremendous number of swarms Hierro has had recently. What I find very interesting as well is the severe punctuality of recordings from Tenerife. That chart is loaded with quakes...NONE of which IGN is reporting. And...from past experience Hierro quakes dont record on Tenerife monitors unless its over a 3.5 on Hierro. Tenerife is getting hammered...and the area between Tenerife and Grand Canary is the fuel station for the volcanic flows to the other islands. Something serious is brewing people.

totally agree

here's the latest EQ map at El hierro..

OP, type 'Slope stability in the Canary volcanoes based on geotechnical criteria' into Google and click 'quick view' on the first link shown.

those quakes at Tenerife take on more significance too.

this entire area is a timebomb

Welcome back....

Shame you had your probs. With the renewed activity, couldn't you do a new thread with all the information from the first post on here and link back to this thread??
Maybe making the title describe the whole of the Canary Islands instead of just El Hierro, this way, if there is activity on the other islands, your thread will always be active....

The reason why I ask is, your da man with regards to the Canary Islands and you have many people who respect you and your information.....

From reading Volcano Cafe, there is defo new activity and GPS movement data confirms this...Also, other islands are feeling things as well...

A new thread could be a potential lifesaver, especially when it needs updating constantly...The threat of a landside is still very real and having a person who knows his stuff, knows where to find it and is the registered OP (Who can update as & when) is highly needed under the circumstances....

While a new thread is a lot of hard work, it could be a life saver when the time comes...Imagine being able to get the information out and possibly saving millions of people if the shit hit the fan with this one...

I hope you think about it....You know your shit and despite your problems on here, you still have many people who respect you and will follow you on a new thread...

You see....

This is why we need you and a thread that the title can be updated...you tell it how it is, we need that....

BTW, I suggest having a read on Volcano Cafe, there is some great talk about what could be happening and there is some great plot Videos and pictures being posted...Well worth a read..

As rock masses are constituted by a sequence of massive lava flows, scoriaceous and pyroclastic layers in uncertain proportions, it is expected that the equivalent Mohr-Coulomb parameters will correspond to intermediate values between the purely unweathered massive rocks and the purely pyroclastic massif. However, the relevance of the relative proportions between rock mass and pyroclastic, dramatically decreases when geologic conditions deteriorate. '

(translation - when magma is injected, and the ground above deforms, the status quo is disturbed, making a landslide FAR more likely!)

At last count there have been 172 quakes listed for today.

cont..

'Concerning this fact, three areas of special relevance have been highlighted for their potential risk of catastrophic landslides in the Canary Archipelago. 'Teide Stratovolcano' (Tenerife), with average slope gradient of 30 degrees, 'El Julan ' (El Hierro), with average slope gradient of 25 degrees and the 'Cumbre Vjeja Rift Zone' (La Palma), with average slope gradient of 25 degrees........ '



cont..

'All of them with slope heights higher than 1000m exhibit conditions of slope gradient that overcome the friction angle of their rock massifs and of low cohesion that became those areas as susceptible of suffering gigantic slides. (HERE IT COMES ..) Internal cohesion will drop by shallow magma injection,..'

Update 16/09 – 19:17 UTC
- 185 earthquakes until 20:49 UTC
- 1 M1.4 earthquake at 10 km, but this was the only one today at this shallow depth
- Diario El Hierro has the stunning title that IGN is analizing the earthquakes. What else could be expected from IGN ?
- Canarias7 could talk to Jose Mario Blanco (IGN). She says that she do not expect the quakes to become stronger than M3.2 at the present depth. She confirms what we wrote earlier on, that the epicenters are migrating gradually to the south.

Nice find AC




From that article:


"Simple erosion or mass wasting processes occuring in previously unstable slopes"


Woah....

I will think about the new thread. You guys have done a great job in my absence. Hierro is a time bomb, as is the entire archipelago. I think we're probably fortunate that Hierro has been the target of all this acivity instead of one of the most unstable islands like La Palma. Hierro has shown her strength.

Are these larger magnitude earthquakes than the swarming in sept 2011? 2 and 3 magnitude is rather large to me.

Woah! More than 50mm elevation change in deformation yesterday

You see why I suggested making a new thread...This renewed activity is going to lead to something bigger me thinks...I know, I know, we have been saying this many times but there only so much magma that can fit under that Island...Somethings got to give at some point....

There is talk about this being the 4th injection of magma under the Island, apparently their wasn't enough pressure for it to erupt last time...

Now that we have a fresh injection of magma underneath the old one, we could get a build up....

I suggest people to follow this thread and the following blog to keep themselves updated on the latest situation...Unless AT fancies doing a new thread....

By the way AT, did you see this....

Thread: Uhh Ohh - Geomagnetic Field Anomalies In The Canary Islands Is The Cause Of El Hierro Erupting - Anomalies STILL There

What makes think La Palma is unstable? My opinion is tha we are exaggerating and focusing on the worst case scenario.
I have posted this before but will do it again so we see another (maybe more realistic) view on this: [link to www.lapalma-tsunami.com]
Please keep it scientific, I don´t say it can´t happen but would rather focus on what is more likely to happen.

Can´t find the La Palma quake, do you have a direct or another link?

Thread: El Hierro / Canary Islands - Most Recent Information By The Most Diligent - And Recap Of Past Year


There ya go folks. I'm still tryin to put all of momma coops links on there for the vast info available through them. But...that's a start!

I'll be posting over there almost exclusively now

where is the accumulated energy chart ?

Agreed!

We might get tropical storm Nadine coming over, don´t panic when the webcams start shaking at the end of next week..

type 'Slope stability in the Canary volcanoes based on geotechnical criteria' into Google and click 'quick view' on the first link shown.

there are THREE threats in the Canaries. La Palma, El Hierro, and Tenerife

volcanic activity under any of them CAN induce a catastrophic slide, and there is activity under or close to two of them at the moment, Tenerife and El Hierro

btw, that link you posted is NOTHING but a hit piece. yes, it's good to see all sides of an argument, but choosing one side over another is silly.

i'm undecided about the ocean basin mega tsunami potential of a slide, but one thing's for certain, it'll be devastating locally, and that in itself would be very VERY bad!

Again I am not saying it cannot happen, I am not taking sides but I only say you focus on the worst case scenario. And that IS taking side..
It is very unlikely to happen and this whole happening has more interesting sides than some doom scenario.
