It can't be live though because it would be dark there now.


ETA: I read on a couple of blogs that it is due to go live tomorrow. Fingers crossed.

Heard someone in passing, mention that they were going to the Canaries on their holidays next week, and it was on the tip of my tongue to say, "Oh there is an active Volcano there right now that they think might go off big style!" :rolleyes: sure Eskimocat :rolleyes:, that's what they want a random stranger to pop up and tell them! Geese!

I'm heading over this day week (to Gran Canaria). Was just looking at the travel advisories on the Dept. of Foreign Affairs website;

http://www.dfa.ie/home/index.aspx?id=8545

There continues to be seismic activity south of the island of El Hierro in the Canary Islands. We advise against all travel to the area of La Restinga (located in the south of the island of El Hierro), which has been evacuated by the local authorities.

The Government of the Canary islands operates an alert system, with green, yellow and red alert levels. A red alert is currently in operation for La Restinga. The rest of the island of El Hierro is categorised as on yellow alert. There is currently no alert in place for the other Canary Islands.

Any Irish citizens in El Hierro are encouraged to exercise caution, to register their contact details with the Embassy here, and to monitor the following Canary Government website for updates: http://www.gobiernodecanarias.org/dgse/sismo_hierro.html.

so seems they see no cause for concern just yet

it seems all the activity has stopped...I hope thats not the end! Ive been waiting for a new volcano/island to break the surface with huge excitement lol:D

Eh!

ok maybe some small earthquakes but they think the vent has closed & there hasnt been any jacuzzis spots. Earthquake report saying its the weakest activity in weeks...just hope it doesnt slow to a stop thats all! I dont know much about volcanos but still in awe over whats happening down there!

The El Hierro 'happenings' got a brief mention towards the end of the Channel 4 News prog this evening.

as above

11/11/2011 @ 07:28 – After a quieter few days on El Hierro, the strongest earthquake yet has hit the island at 00:20 this morning, a magnitude 4.6 on the Richter scale. It was said to be felt in Tenerife.

things may kick off again.

11/11/2011 @ 14:23 – The director of the National Geographic Institute has said that they are expecting a possible double eruption to the north of El Hierro both underwater and on land, according to the latest data available to them.

Weylin

November 10, 2011 – CANARY ISLAND – Spain’s Civil Protection for Volcanic Risk has closed two beaches on the island of El Hierro in the Canary Islands because of potentially toxic gasses emanating from an underwater volcano off the island’s shore. The decision came after a technician from the country’s National Geographic Institute had to seek medical treatment after he was taken ill while measuring carbon dioxide levels there the previous day, Spanish TV reported. Authorities on the island insist there is no major risk for the population. In the nearby village of La Restinga, one resident said he noticed unusual behavior from a member of the local feline population, which was scavenging along the shoreline. “We were looking at a cat that was eating in these pools, and the fish in them were dead. We thought the cat was some rare breed, and was it normal that he was eating dead fish,” the man said. The island has experienced hundreds of low intensity earthquakes due to volcanic activity. Witnesses say that explosions from the underwater volcano sometimes blasted 25 meters above sea level. -Telegraph

Another webcam... this one seems to work. The two tabs show different views, one with the town and the other zoomed to the sea.

There's been a spike in the tremors in the last few minutes, if you can see it in the graph properly :P Waiting to see if anythings reported. The webcams have gotten a bit shaky since about 3.15



EDIT: It's calmed down significantly now. Around the 27-30 minute mark, there was some large spiking and some steam rising from the sea

I can't tell if its wind or not but both cameras mentioned above are shaking a good bit!

Saw this too, is your image a screen grab or a download?

Maquiladora spends 3 and a half months telling us the daily possibility of the impending eruption.

Volcano erupts and maquiladora disappears.

Maquiladora thinks it more interesting when a volcano is about to erupt rather than when its actually erupting....

How does this make sense?

Yep. Readings are off the graph once more, back to similar readings before the opening underwater. Something else is brewing!

For those of you who read Jon Frimann's blog and may have missed it, and others of you who are adding to their volcanic bookmarks, some of the regular posters like Lurking (with his brilliant plots) and Carl le Strange due to a difference of opinion have broken away and formed a new blog of their own.

Thanks for link , I think carl was totally childish, they messed up a blog that was going so well, dont think I want to follow because of that but I probably will out of interest in what they write.

I don't think they were childish and I don't think they have messed up Jon's blog. I believe something like that was bound to happen. Lurking and Carl between them answered about 90% of questions asked on the blog. If they hadn't it wouldn't have been quite as informative as it was as I've noticed Jon doesn't tend to answer questions much. So when a couple of new names suddenly start bitching about off topic chat and they started getting virtual raps on the knuckles, I imagine they felt, as adults, that given what they put into the blog they were entitled to get annoyed. Obviously those new posters hadn't been following the blog for long so perhaps did not realise that the bulk of the information there came from the two of them.

In my opinion, Jon should have stuck to Icelandic volcanoes, and Erik over at Wired should have checked out how the volume of traffic on his blog would work in sync with Wired. I only check Eruptions sporadically now as the Wired set up is slow and annoying for an old stick in the mud like myself whereas when it was on Big Think I had it permanently open as it was clear, quick and easy to follow. But what do I know! I'm a blog whore so I follow as many of them as interest me.

Totally agree - I have followed Jon's blog for some time and can't quite believe how quickly relationships deteriorated between some of the main contributors there. I still follow jonfr and occasionally drop in on volcanocafe (and feel a bit guilty about it) but sincerely hope that Jon's blog continues successfully.

I see your point there but from what I read Carl left the blog because Jon was adding a forum to the blog for off-topic conversations but was keeping the blog as was, and from what I saw Carl threw a strop like a child and refused to even see how it worked. Whatever the reasons anyways its a pity to see it divided was nice to have all the information in one blog.

Thanks for your links anyways always find them interesting and like you will probably follow both blogs!

Research ship at site of eruption today

https://www.youtube.com/watch?v=GU_AU7Utf2U

According to earthquake report: "The eruption webcam has not zoomed yet, but we see a well defined eruption vent in the distance. The vent itself is at the left side of the lighter stain and the sea current (wave direction) is pushing the erupted material to the right. The position of the event is similar than a couple of days ago ."

ednwireland

jeez you'd think it would stop teasing and break the surface, i excpect a new ryanair destination shortly afterwards

actually, seriously whats the prospect of it breaking through and creating a new island ?

Today on the Beeb.

Elsewhere, tremor count.

Hope those tremors do not continue to make their way north to La Palma, as they look like they are doing. Any eruptive activity there could be somewhat dangerous.

Long way to go, the northern swarm does appear to be spreading northward a tad but by a tad I mean 1 or 2 km.

In case anyone wonders why La Palma is more important than El Hierro I suggest they read this first then this

heres an update from the El Hierro President, from yesterday. Some very interesting points.

Diario de Avisos had an interview with Alpidio Armas, the president of El Hierro. One of the most important quotes Mr. Armas said, was that the volcano grew 80 meters the last couple of weeks. The change in depth was measured by the oceanographic ship Ramon Margalef. The first bathymetry took place on October 24 (2 weeks after the start of the eruption) and the last one last week. Mr. Armas also said that according to the data of the Ramon Margelef 3 vents are active now and then.


What to expect next ?
Based on Mr. Armas interview and taking into account a number of uncertainties, Earthquake-Report.com expects that :

- if the eruption continues at the present rate and in the same vent, it will take max. 2 weeks to arrive at a depth less than 100 meter. We than expect very strong Jacuzzis during the hydromagmatic bursts.

- if the same process continues for about 3 to 4 weeks and in the same vent we expect regular hydrovolcanic explosions during the bursts.

- if the same process goes on 5 to 6 weeks the eruption may become Surtseyan. This is the most spectacular phase of the eruption. During this phase of the eruption ash and steam clouds can reach hundreds of meters to several km in height. Particular to Surtseyan eruptions are the thick,dark-pointed jets of fragments, often headed by bombs, shot out of the vent.

- if the same process goes on 7 to 8 weeks and in the same vent, the eruption will have created at least a new island
- the main vent is at a safe distance from La Restinga, so we do not see immediate danger for the population. 90% of the time the wind blows from the north or north east at this time of the year and accordingly the eventual ash will be blown further in the Las Calmas sea, avoiding damage at La Restinga..

- If a new island forms, it may indicate several months of uncertainty for the La Restinga population as nobody knows how long the eruption will last and when it will finally stop for a longer time as there may be several new eruptive periods.
Our expectation is based on medium harmonic tremor like we had the last couple of days. In case of strong or very strong harmonic tremor the time to get to these different phases may well be a lot shorter.

If our expectations are coming true, the eruption will make El Hierro appearing in every news show in the world. The island will start to attract visitors from all over the world.

hidinginthebush

Great post jake1. Are there any guesses as to how long the eruption will go on for? Would be great to see footage of a new island spouting!

Sponge Bob

Overall the seismics are much quieter in the past week.

Speaking of new volcanic islands, here is one in the Red Sea


An eruption occurred in the Red Sea in December 2011. According to news reports, fishermen witnessed lava fountains reaching up to 30 meters (90 feet) tall on December 19. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites observed plumes on December 20 and December 22. Meanwhile, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite detected elevated levels of sulfur dioxide, further indicating an eruption.
