Update 14/02 – 08:55 UTC
- HT (harmonic tremor) has been at minimum all night
- The vent emission point is very visible on the webcam, although a strong surf is hampering visibility. Hopefully there are no SLS this morning because if the Salvamar Adhara would go out to the vent, it may lead to a very bad stomach feeling for the crew.
- 3 earthquakes since midnight UTC. Based on the location of the epicenters, we can conclude that the magma is till active and present from Frontera to the greater vent area to the south of La Restinga. The only difference with a couple of months ago, is that we have less earthquakes in the sea to the west of Frontera.
14/02/2012 00:42:01 Depth 17 km M 1.1 SW FRONTERA
14/02/2012 01:15:10 Depth 12 km M 1.6 W EL PINAR
14/02/2012 07:22:43 Depth 16 km M 1.1 SW EL PINAR

The only fact we got is that an eruption at the ocean floor is going on. Don´t be so agressive, makes you look insure.
Define "recent" and explain why I as a person am dangerous?
Let me be clear that I also am following the happening as I am not naive. I know there is a risk but we have to stay realistic. I mean even boats passing by are suspicious terroristic, people move from the coast in the USA, WTF?? That´s pure panic!

"Important Update 14/02 – 13:58 UTC
- ER reader Max just wrote in the comments section that local newspaper Canarias 7 cites PEVOLCA that 2 active cones have been detected (probably during the latest bathymetry from the Ramon Margalef) in the current area"

Lots of strange new lights on the eruption cam. They appear to be stars maybe? But...they seem way too close and too low to the water. Any ideas? There are no boats in the area according to localizatodo.com

Not sure if we talked about this or not...volcanic eruption in eastern Africa

Major sandstorm just east of the Canaries...in Africa

[link to hisz.rsoe.hu]

the ones saying that are idiots though. we have every right to keep an eye on things, and whether or not you live there makes no difference.

IF the worst case scenario did happen, i'd want to be right on top of it, because it has the potential to affect me and my family.

i'm still not sure about any mega tsunami potential though, from an island collapse.

Define "recent"

there have been multiple collapses in the recent GEOLOGIC past. I'm talking before written human history, of course.

[link to img.over-blog.com]

they ALL happened during volcanic activity, so while this thing is rumbling, i'm watching it.

what you have to remember is thousands of years long dormant volcanoes, such as Chaiten in Chile, for some reason have decided to wake up recently, so events that happened long ago repeating now are not so far fetched really, are they?

even if this thread only saves a handful of people's lives who happen to read it, and manage to get out of the way of the wave, however unlikely it may be, it's done a good job.

This is true. The event is unlikely and they only happen every X amount of years, but I've let a dozen people who live on the eastern seaboard know about this.

They had zero clue, no idea of the existence of this much less the danger, yet they will be more alert and possibly save lives in the event anything drastic happens.

Sure anyone expecting this thing to go off everytime a seismograph ticks may be reactionary, but this thread is probably the most informative source and will actually save lives in the event that some unpredictable series of events you or I can't fathom take place miles underground in an active volcanic area. As long as the possibility isn't 0% you can spend a few minutes acquainting yourself with the phenomenon and looking into it.

I'm sticking here...not going anywhere. I realize the 'big event' happening may be unlikely, but it is also possible. Anyone in an area that would be affected would be wise to at least keep an ear/eye on the happenings in the Canaries. IMHO

I noticed that there are a lot of quakes these days and yet no real talk about it. We went for over a month of 0-2 quakes a day. Now we're back up to average of 9 or so...nobody mentioning this uptick and what it means.

Despite the fact that IGN changes their information on a routine basis once it has been published on the internet, the pattern is still showing a very gradual rise in the depths of quakes. Averaging around the 15-19km deep range in the past few months, now, in the past few weeks, the range is up to around 8km deep. And, it's not just in the eruption area near Restinga/Pinar. The shallower depth quakes are also showing up in the Frontera region on the north and west sides of the island. Even the quakes on land are showing up more shallow. I think we can anticipate that this shallow depth will only grow more shallow. I also forsee, if this depth continues to rise to the surface of the ground, that we may in fact find multiple eruption sites eventually. We may have numerous vents forming.

[link to www.01.ign.es]

This list shows that once double digit depth quakes are now almost always in the single digit range. It is important to note...IGN often posts a depth much more shallow, down in the 3 or 4km depth range and then over the course of 12 hours or so, often changes the depth to 7 or 8km. I don't know they insist on doing this...especially when the deeper quakes rarely get their information changed at a later date.

Over the past two weeks there has been interesting earthquake activity in El Hierro volcano in Canary Islands. What is so interesting about this earthquakes is the fact they are getting more shallow every day or so. Currently the most shallow activity that has been taking place is around 6km depth. But this is an rise from about 12 km depth.

What this means in my opinion is that magma is most likely rising to the surface at the location where the earthquakes are currently taking place (dike intrusions). This did happen before the first eruption in Eyjafjallajökull volcano. So it is an important to keep an eye on this earthquakes and where they happen, as eruption might take place in nearby area of this earthquakes. As magma might, and most likely is going find an clear path to the surface soon. The last part of that before an eruption might happen with no noticeable earthquakes at all. They might well be just over ML2.0 in magnitude or smaller.

Idgits

There have been six earthquakes today already !!!!

List earthquakes
- the numbers above are clear signs that the pressuring magma is more active than ever, which will make the near future very unsure. Why ? The current eruption flow is not big enough to keep the pressure from below at the same level (increasing number and strength of earthquakes). If HT remains at the current low amplitude, the number and magnitude of earthquakes will gradually build up to several tens per day until it finds a way out. The same vent ? Nobody knows. All scenarios are possible at that moment, also the complete stop of the eruption.

Hi all ,


Interesting earthquake activity in El Hierro volcano

Good morning

I keep managing to post after being signed out (without realizing it). Sorry. Anyway this was my post and is exactly how I feel about it.

ah big thx luis

added this blog

You don't know it? It's great! Thank's for karma!

Thanks Luisport. Interesting read.

Thanks for posting big guy...she seems to be getting more active!

We're actually at 16 quakes for the day so far with 8.5 hours left to go!

[link to www.01.ign.es]

There have been 2 quakes in the 2.0+ range and most all of these quakes have been in the 10km range. In addition, they've almost all been in the south near the eruption area.

earthquake-report

Update 15/02 – 19:11 UTC
- 3 more earthquakes : we will from now on only change the number in the title.
Nobody knows what will happen next but CAP science center in La Restinga and IGN Madrid, who is following up the instruments via data link, will certainly be on a higher alert than normal.

Update 15/02 – 17:52 UTC
- 4 more earthquakes ! , which brings the total of listed earthquakes to 20 today, the most since many months !
- we have still a minimum HT signal which means that the eruption is still hoing
- NO jacuzzi or even stirring area anymore.

'What one should look at is the 0.59Hz tremor given by EOSO and EGOM stations. That is probably the tremor from the deep feeding tube. It might even be from the mantle plume.'
