as first report for June- 
very good video about  volcanism in the AFAR triangle I found on youtube: The african plate is just the aneighbored plate to the Canary islands and plate movements there have  much influence on the Canary Islands.

ACTIVITY REPORTS/ JUNE 01- 30  2014:


JUNE- 20- 30 - 2014


JUNE 30- 2014:


Another quake - propably a volcanic inflation- occured on June29 near a seamount between Teneriffe and Gran Canaria-. The seamount has no crater yet, but is suspected - or wished by the experts to become another volcano or volcanic islands .



This activity again   followed  another short magmatic boost below  El Hierro on June 26- 28. resp. three more - likely volcanic-  quakes below El Hierro on June 26- 28:

Not much happened anymore in the second part of June 2014- after what was- due to an expert most likely a " volcanic deflation"- following the first observed  "inflation" below Teide in May 2014.

JUNE- 18- 2014

another- as AVCAN still hopes " isolated phenomenon  of " volcanic activity below the Teide Massiv on Teneriffe on July 19 : ( the two quake fon JUne 20 occured in  higher depths on a faultline between Teneriffe and GranCan and  are likely related to the tectonic movements on a larger scale" as observed  over the past months:

JUNE 19- 2014:

Today AVCAN published that exciting  sound recording form the inside of the Teide volcano system and the geologist  who is in charge of the AVCAN youtube channel was able to give my a first and honést  statement to my question how likely he believes might be a eruption on Mount teide now:, I am really grateful for Thanks! here the text:

Dear Helmut. We are dealing with volcanic activity that started at 02:22:50 and ended at 02:39:16, full stop. A typical volcanic swarm like the one in El Hierro had a much more diffuse distribution in time and in crescendo. WHat you've heard are typical cracks due to inflation or deflation, (time will tell), well grouped, propagating, starting at 2,1 Km and descending then to 4.8 Km. Which leads me to think  in a zip like fracture. Hence Isolated in time and depth.

here the "audification":

UPCOMING ERUPTION OF / ON MOUNT TEIDE/ TENERIFE?

update/ Juni 18- 2014/ 14:22 UTC

The earthquake swarm below Teneriffe continued on June 18 with at all 6 quakes above M 1 at time of this update:

AVCAN facebook: remarks; people should remain calm and should not make emergency plans on their own . AVCAN cannot afford to say something like " our volcano is likely going to erupt soon" as this would just create panic among the hundredthousands of tourists on the islands, those would look for a way to escape form th island and overrun the airports and harbors  But halfway understanding Spanish I read their  bulletins on the seimic swarm today, in those they just say itnthrough the backdoor:  such as by remark that "people know they are living on an volcano archipelago or with remarks such as " the last known two   historical eruptions on Mount Teide 1704- 1706 Arafo, Fasnia y Siete Fuentes just costed 16 peoples´lifes and the one around in the 18 century even just 2 lifes . This all  tells us clearly that also they contemplatively  more or less would expect any kind of surface  eruption now. Just some month ago they Canary administration and the government of the azores had created an emergency plan and a field exercise for a possible eruption of Mount Teide, in which they likely plan to evacuate people from the Canaries to the Azores islands if necessary. 

However : AVCAN turned out to be rather competent without creating any panic at any time when  there was not reason for. They will keep an eye on the situation and issue advices at the right time, if necessary....

Since March 2013 experts waited for any surface eruption (as expected first , again south of El Hierro)  but no even 1 single magmatic quake happened since then from a depth of less than 11 km ( where supposedly the mantle plume below El Hierro  ends and from where the magma since then ran  into fissures and hollow spaces of the old Canary caldera). Since begin of this new and jet strongest magma intrusions since December  2013 the harmonic tremors ( standing for heat effects of the hot magma in the underground) where strongest on Teneriffe . And repeatedly  uprising  magma if it can cool down and harden out in between as it happened here since March 2013 can of cause form a new magma chamber or bubble with in such a large and  broken caldera as the Canary one, capable to create the pressure necessary to trasnport  the hot and viscous hot spot magma finally to the surface

Since April / May 2014 now the first quakes near Mount Teide  from a depth of less than 11 km!I ( counted from sealevel):

( you find all earlier quakes in my previous blog pages)  

AN ISOLATED EVENT?

These microquakes  from gradually more shallow depth  are the first of their kind observed since March 2013  and are - so my amateur opinion- a clear indicator,  that magma there is NOW INDEED rising up to the surface where it can also mix with water to an explosive  mixture!
The first of these quakes observed since April/ May 2014 came from a depth of 7 km,  the next from a depth of 5 km. On June 16 we now had one single magmatic quake from just 3km depth (see report below) and today. on June 18 two magmatic quakes yet from  the depth of 2 km and less :



The epicenter of the latest quake was near Granadilla de Abona on the Southern slope of Mount Teide

here, the recent epicenter  map as published by AVCAN on their facebook page:



here the related comment by AVCAN on 20140618 :(engl translation)

"A small seismic swarm, of low magnitude, this morning, has been developed in the vicinity of the southern slope of las Cañadas del Teide. Their magnitudes range from 1.6 to the 0.5 mbLg. Highlighting as shallow in its depths, ranging from the 1.9 to the 0.5 km. noted that it has developed in a narrow strip of time, between the 2:22 and 2:39 hours of this morning, and is likely that it may be an isolated phenomenon. Stay tuned. "

an isolate pheomenon we observe since May 2014, with quakes gradually rising up into more shallow depth? As asked AVCAN to  explain why this is regarded as an "isolated event", if this development can be observed with increasing intensity since almost 2 month?




-----------------------

JUNE 15- 2014:

today an M 1.9 magmatic micro quake occured in a depth of just 5 km , The epicenter was very near to the Teide volcano crater on Teneriffe. I would assume, the the depth "zero"  represents the global sea level.



Nevertheless Tremors on Teneriffe  have  only low intensity  today, but are not a true indicator anyway, if magma now really would rise further upwards  to the surface:





--------------------

JUNE 12- 14- 2014:

One minor quake on June 14 in 16 km depth, some 5 km west off the coast of  the southern El Golfo Valley:

Tremors are also very low on all islands,. This lets consider, that the overall  volcanic activity  is currently at a very low point.

JUNE 07- 11 - 2014:

A single magmatic quake occured on JUne 11 on El Hierro in 11 km depth near to the yet inactive craters in  the Southern part of the island. It was the first since May 28.

OTHER NEWS

EIFFEL VOLCANO FIELD/ GERMANY 

Another M 3.3 quake occured near the German city Darmstadt on June 08  in about 70 km SE distance to Lake Laach with  a depth of 5 km.  There were no testimonies yet,  that the shock was felt aynwhere in the region. Its just the second  yet in 2014 that occured in a distance of less than 100 km to lake Laach and might be related to magmatic activities in  the Eiffel volcano system .
In 2011 and 2012 about 3 stronger shocks had occured nearby  resp.  not more than 10 km away from  Lake Laach, which is just the last known active crater of the Eiffel volcano field

Its the second quake in  2014 that occured near the EIFFEL VOLCANIC FIELD IN Germany on June 10 2014 and is most likely related to magmatic movements in the Volcano system and mantle plume. Earthquakes are at all very rare in Germany. 

Its even extremely seldom that the fault reaching from South Italy through the Alps into Bavaria causes any earth shock that can be felt in Germany . There have been more minor earth shocks ( up to ten per year ) in the recent years,  those regularly occure now  in the NE of Bavaria near  the border to Cech Republic an Poland. Both phenomenons are related to subduction processes between the Eurasian and African Plate - overall an subduction force,  which is much  weakened by the massive alps in their north, while it  causes regularly strong and destructive Earth quakes in their South ( compare: Aquila) 
Since several years also more and regularly microquake occure mainly in Northern an Central Germany  and- put on a map- they are all localised in a radius of  up to 300 km around the Laacher lake which is regarded as the last active vulcano crater in Eiffel volcano field. The Eifel volcano field is barely observed and not  surveyed  with any constant system, allthough the supervolcano.made the latest known Supervolcano eruption on earth in  recent history ( around 11.500 B.C) . The Eurasian plate is likely on of the thickest on the planet and the mantle plume of the Eiffel volcano is believed to be in a "world record" depth of 37 km!
However. privat volcanologists those already have examined the volcano in 2010  found , that CO2 emissions through Lake Laach  had increased  in 2010 , what means that the hot spot also became more active at this time with an increased  magma intrusion as so many others on the planet:. 
Please note:  This  does not mean, that  the Eiffel  volcano would pose any real danger at the present time!


The location of the quake was in about 60- 70 km distance South East of Lake Laach

---------------------

JUNE 01- 06- 2014:


There was not further magmatic quake nor any other indicator of volcanic activity since May 28- 2014.
