------------- ACTIVITY REPORTSJULY 28- 31- 2014
No significant change: One more quake below El Hierro on July 29 and another one on the fault line between Teneriffe and Gran Canaria:
------
--------------------------------
JULY 22- 27- 2014Canary quake activity continued in the same pattern as during the past months ,with magmatic quakes below El Hierro in just lower frequency and an average depth of 10 km and several minor quakes between the islands. in an average depth of 20 km and more, those are likely related to tectonic processes on a larger scale:
The strongest shock measured M 2.3.from a depth of 32 km and occured again on the fault line between Teneriffe and Gran Canaria:
Another M 1,9 shock form a depth of 34 km was measured near Gyanmar two kilometers offshore the northern coast of Teneriffe :
TREMORS:
Tremors dropped to low intensity- possibly a sign that the new magma that surged up since December 2013, might now cool down, after it would pose no thread anymore.
The seismograph on Tenerife still shows stronger ongoing activity below the islands. Such a strange pattern was already frequently observed during this activity period that started end of 2013, but was falsely believed to be a malefunction - FREQUENT QUAKES ON THE MIDATLANTIC RIDGE:
A shock from a quake on the midatlantic ridge on July 27 at 01: 30 in the morning was measured on all of the islands and caused tremors from 01:33 UTC until 2: 05 UTC. The measured values were relatively strongest near La Palma:

DEFORMATION ( EL HIERRO)
remained stable with a short up and down movement during the midth of July 2014:
------------------
----------------------------------------
JULY 13- 21- 2014
Canary quake activity continued about with the same rate as during the past months ,with further quakes below El Hierro und 3 in between the islands. The depth of the magmatic quakes below El Hierro remains with 9- 12 km on the highest level, the magma intrusion responsible for seems to have reached yet.
The Atlantic quake on July 16 occured in just 9 km depth and now first time in the yet unaffected sea between La Gomera and Tenerife .
Its epicenter was subseas between Sebastian de La Gomera and Puerto de Santiago on Tenerife:
The other atlantic M 2,7 shock had its epicenter about 50- 70 km south of El Hierro in a depth of 30 km ( The deeper quakes are related to tectonic activities on a larger scale)
the third Atlantiuc quake occured again on the fault line between Teneriffe and Gran Canaria:
-------------------------
------------ JULY 08- 12- 2014
activity below el Hierro continued on the low level and rate as observed in recent time:
TREMORS
continued on the low level they had decreased to on July 05 and are still relatively strongest on Gran Canaria:
DEFORMATION / El Hierro:
There was no further deformation in June 2014:

------------------------
JULY 01- 07- 2014
last quake:
20140705/ another minor quake on the fault line between Teneriffe and Gran Canaria in a depth of 32 km, which seems to be related with tectonic processes on a wider scale but is not caused by magmatic activities from the hot spot below El Hierro:
Magmatic activity below El Hierro continued during the first week of July 2014 with low rate :
TREMOR ACTIVITY
increased after July 01 on El Hierro
and decreased again to low levels until July 05:
tremors are currently strongest on Teneriffe:
