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

OK, what you have to do is hit 'reply' to this post, then C+P the link as it appears in the post!

Wonder how he is getting that number?

Sorry its a bad link

I went to the main site and typed in el hierro and alot of articles came up. What is the doc name?

type in search browser

CRcnetbase.com and then search el hierro, a bunch of docs come up so I need the name of the article a\c

Ok never mind I found it, its called chapter 24 slope stability in the canary volcanoes, i will give it a look and post anything important.....

What happened to Id*gits??

He said he had to delete his account for personal reasons and then starts posting under a different name saying he is popping in and out....

If he is popping in & out, why didn't he keep his old account? His name has been taken off all his threads, is that what happens when you delete an account??

Just find it weird.....

He deletes his account and then there is renewed activity...

Has he got the feds after him??....

He said it was for personal reasons. So I'm not asking. Just take it for what it is.

Update 15/09 – 16:12 UTC

- 110 earthquakes. Depth 20 to 22 km. All of the epicenters (last 10) below the historic main crater. It looks like the magma has settled below the current area

updated pic....15780 and counting...

Thanks

This Blog is from a German resident, if you look at the second picture you see the epicentric line. That would cut the island in half and I live 100Km away...but fortunately at 1000m altitude. (I can see the N-west-side of El Hierro from my desk here) But I think the eruption will take place in the southern oceanfloor again. At least I hope so. [link to elhierro1.blogspot.com.es]

But they´re still deep, this could continue for a very long time as well.

Good Morning

Update 16/09 – 12:00 UTC

- 100 earthquakes until 11:19 UTC

Update 16/09 – 12:00 UTC

- The activity subsided a bit, but there have been some more quakes after 08:48 where IGN has stopped listing

Update 16/09 – 09:38 UTC

- 85 earthquakes so far (until 08:48). the last earthquake was a M3.0 at a depth of 19 km
- It looks like IGN is also listing weaker earthquakes now. A 0.9 figures in the list.
- Epicenters are moving a little south

Update 16/09 – 07:46 UTC

- Until 07:35 today, IGN has listed 73 earthquakes. Magnitudes vary from M1.4 (the weakest they are listing but there are hundreds more below this Magnitude) to M2.7. Maximum magnitude decreased a little bit from yesterday (up to M3.2).
- Focal depth remains the same (no penetration into shallower layers)
- Epicenter location is fairly stable (see image below and compare it to the last images yesterday)
- NO more (listed) earthquakes in the El Golfo bay at the 10 km depth layer.
- In line with what could be expected is that the deformations are up again.
- Frontera GPS station has moved North for about 1.5 cm and was also lifted with about 2 cm.
- El Pinar GPS station showed the same movement.
- Restinga GPS station moved a little eastward, did not move along his latitude axis and was inflated most of these 3 stations.
All these data were Ultra Rapid data coming from Prof. Sagiya, a GPS authority in Japan working at the University of Nagoya.
All the mentioned stations operate automatically, which means that nu human is needed to send the data to the computers of the University. Check PINA, FRON and REST stations here.

if those el julan cliffs go, even that might not be high enough locally

imagine the deformation affecting those cliffs, which is one of the precursors mentioned in that link you can access by typing 'Slope stability in the Canary volcanoes based on geotechnical criteria' into Google and hitting 'quick view' on the first link shown

Just had another 2.8.

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..

on page 4..

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....
