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

23 quakes thus far already today! Something is happening folks. No increase whatsoever in the harmonic tremor and the jacuzzi is practically silent. What do you think is happening? I think we're seeing an expansion in either the magma chamber or the magma tubes. And...we may see surface strength giving way to the long duration events on Hierro. [link to www.01.ign.es]

note...we've had another 2.0, that makes 3 at the 2+ range today. [link to www.01.ign.es]

All of this activity and yet the seismograph is basically flat lined. Remember...it was believed early on the Hierro is siting on top of 50,000 sq. Meters of magma. That is crucial in realizing why many quakes aren't showing up on the seismo on Hierro. It's masking, dampening and drowning out their signals. [link to www.01.ign.es]

So... Should those of us on the East Coast be ready to leave at a moment's notice again?

AC...not until you see a 4.5 or bigger. Even then...just pay attention, we will keep this thread updated as often as possible.

''Magma

In the beginning we saw pretty much reactivated old evolved magmas and semi solid rocks being erupted, after that followed a long phase of what probably was reactivated rhyolitic mush. That would explain all the ash in the water (suspended tephra) that we saw back then. Now all of that is probably cleared away and we have an unevolved stream of basalts comparatively low on gasses being ejected. This basalt is of deep origin as evidenced by the UrTh (Uranium/Thorium) content in the samples that has been collected from the surface.''

so, basically, a flood basalt eruption?

i'm wondering what this much hotter magma COULD do to those cliffs, right above it.

It could be the adipose (correct word?) of the Canaries. The New Zealand and New Guinea regions have been having some 6.0 quakes recently. Possibly connected? There's also a volcano going off in West Africa right now...not too far from the Canaries. Could be connected?

the antipode is east of Australia.

quite an active area

AC369, for a while we reviewed the idea that magma was actually making its way from La Palma to Hierro and that a giant core was actually sending magma down tubes from a point directly between Tenerife and Grand Canary Island. This study had an awesome yield of information for a couple reasons. Forgive me...I'm currently on some heavy pain meds due to a neck injury somy memory isn't working really good on names. But...there are 3 different types of volcanoes in the Canary Islands. Basaltic Shield volcanoes like Hierro, Strato Volcanoes like La Palma and one other type on Fuerteventura or Lanzarote. I can't remember the name of the type. Anyway...if they're all coming from one source between Tenerife and Grand Canary then...how does it change so quickly and completely in less than 100 miles from the origin? And...if La Palma's strato volcano is feeding Hierro's basaltic shield volcano...how is it processing the new type of magma? Well...that interaction occurred a few months ago and we saw massive magmatic explosions showing up on the seismograph. In fact, the explosive nature was so intense IGN actually had to dumb down the sensors because they were being ruined and drowned out by the magma flow and explosions. The big expectation is that this underwater volcano will soon enter a Surtseyan Eruption phase. This is when it's going to get super hairy. We had a small version of this a few months ago and boulders the size of volkswagens were seen hurled out of a 30 meter high rumble of water. Great points! Great questions!

antipode...thank you! Adipose refers to a certain dorsal fin on our native trout here in California. Thank you :) you rock!

A great source of info for those who are fairly new here. This explains A LOT about volcanoes [link to www.waterencyclopedia.com]

Another highly educational link for new comers who haven't been able to survey all the info in this thread or old comers like me who have simply forgotten :) [link to en.m.wikipedia.org]

If this is going to be anything like the runs before the October quakes and eruption...then we should soon see quakes in the low to mid 3.0 or higher. I'm assuming the 3.2 recently caused some changed that allowed the increases to start up. Another 3.2 or larger SHOULD be on its way soon!

this graph was last updated about 5 hours ago. There could be a vast number of quakes not recorded yet over this past 5 hours. There's still almost another 50 minutes to go in this day (UTC) we could easily break 30 once all the numbers are in!

I would totally not be suprised to see IGN add quakes to this list later. They say 23 for the day. That's amazing! [link to www.01.ign.es] If I'm looking at this right...this is the most amunt of quakes since November. This looks like the biggest day of quakes in the new year!

The submarine eruption south of El Hierro Island could be in a process of change: While visible activity on the sea surface above the vent, as well as harmonic tremor signal (thought to be more or less proportional to erupting magma flux) have nearly ceased, the number of earthquakes under the island has increased sharply since yesterday.
On 15 February, more than 20 quakes were measured. Most of the earthquakes were very small, well below magnitude 2, and were clustered beneath the NW and SW sectors of the island at depths of around 10 km.

It is birthing New land

Please excuse if already posted but there's significant stuff happening. Stay safe everyone [link to theextinctionprotocol.wordpress.com]

WOW! 23 quakes already today!!! This is amazing. [link to www.01.ign.es] This sets us at a tie with yesterday and we still have 7 hours to go on UTC time.

History Channel documentary on possibilities for major solar storm in 2012. This video has excellent information and interviews with experts. This is a very informative video from a very well-known credible source. About 9 minutes in length.

Not to say that solar activity can't contribute to erthquake activity but since I started watching this Hierro situation, I don't believe there has been a single earthquake connection to solar activity in the Canaries...or anywhere else for that matter. We have seen some really nasty flares pop of and hit earth with no earthquake activity following. AND we have seen good sized quakes occur when there's been absolutely no solar activity. I DO THINK that other planetary bodies play a role in earthquakes though. When we've seen alignments and stuff happening there are often quakes following those events.

29 quakes so far today with 3.5 hours still to go in the day. Hierro is going again! [link to www.01.ign.es]

OP - It is rare that I see one with such stick-to-itiveness! I salute you my brother! May you prosper and be well!

Black Knight - anytime the old lady wkes up like this II'm on it! :) we reached 30 quakes for the day yesterday UTC. [link to www.01.ign.es] However, not a single quake at or over 2.0, I think that means a big one is coming!!!!

Wow! I tried to research the deep quakes we have been seeing over the past few years, of 350 - 800 kms depth. The only explanation I could find was by a Russian scientist, from studying a big Russian volcano. I couldn't copy the text, as it was all protected and hard to link to.

He said that at that depth you had the really deep chambers of magma, below all of the really big volcanoes. Rumblings down there could only mean that they were about to empty upwards, into the higher, and then even higher, chambers of the volcano.

So if this is happening in Indonesia, near the Phillipines, Fiji, Vanuatu and Japan, and the Canary Islands, it doesn't bode well. The deep quakes then started up in some other places, I can't recall them all at the moment though, but I think it was near the Aleutian Islands and off South America?.

Interesting about the Russian report. Thanks for sharing. You may also look up types of volcanoes on Wiki...there's a huge amount of info on the wide range of volcanoes and the way the magma feeds it.

we're on track to see similar numbers of quakes today as we have seen the last 2 days. Eleven so far today with a 2.5 that just ocurred. Good stuff manord! [link to www.01.ign.es]

There is a boat operating on the water, can be seen on the eruption cam. Looks kind of like the Ramon Margalef but I'm not sure if that's it. Localizatodo is not showing any boats directly in the vicinity. HOWEVER...there is another Lebanese ship entering the green goo area very shortly. It is described as livestock carrier, cargo ship. It is called the "Rami M"

The ship that was on the eruption cam is not showing up on Localizatodo.com, and I'm curious about that. As far as I know of, only military and police vessels are kept off the screen for obvious reasons. For this particular boat to NOT be shown on Lozcalizatodo tells me they're doing something that is regarded as classified or secretive.

Here is the link to the cams
