OCTOBER 20- 2015:


Microquake activity on the outer Northeastern Rim of the old Canary caldera continued and increased over the past days. Indeed this new evolution started in early October 2015 and marks likely another way the hot magma in the underground can burst free to find empty space where it still can run to and expand . Since the third activity phase has began in december 2013  and the old channels below El Hierro where sealed with the hard mantle lava  by the eruption in 20111/ 12  the upcoming magma  runs to where it finds lowest  resistance . The canary island caldera  indeed represents  a  extraordinary high resistance  caldera  created by the large coverage with sea sediments  brought along by the strong sea currents around the islands.

comment on AVCAN facebook/ 20151020:

Seismicity in the eastern part of the archipelago with two earthquakes, one of magnitude 3.0 and another in 2.7.-the first of the earthquakes has been on the west coast of fuerteventura this morning at midnight last night, while the second has Been located north of Lanzarote in the area of the chinijo archipelago one hour and forty minutes past noon at a depth of 15 km which has been marked in almost all of the stations of the archipelago."


The two quakes measured M 2 .The last had M 3.0. which is the highest magnitude since more than one year. My Conclusion; the magmatic intrusion is still continuingand the pressure on the top sedimentg layer of the claldera between the islands and the volcanic systems seems now significantly to increase what is an indicator for an likely explosive eruption on the surface anytime in the next future- possibly already towards the end of the year or within the first half of 2016, depending only on the question whether the magmatic intrusion from the hot spot continues or not.

OCTOBER 10- 2015:


Another shallow microquake was registered by IGN on 20151008 offshore west of Lanzarote island in the Northeast of Gran Canaria .It can`t be approved whether that quake was magmatic : I suppose it  rather was magmatic and might indicate that magma is still continuously rising  (whereever  it can find lower resistance) within the old caldera between the islands resp its edges up towards the surface.
These microquakes might be the only indicator we have that can tell us,  where about any surface eruption might occure within the next future: This might be the case about at end of 2015 or some months.later, so far as the magma intrusion from the hot spot South of El Hierro continues in the current pace) :

OCTOBER 02- 2015:


Activity was rather calm throughout September 2015.

Now towards the end of September, two minor new SEPs ( solar proton events)occured on the Sun and were likely the cause for another increase in hot spot activites- in form new magma intrusions.


The SEP on September 30 (geomagnetic proton impact time: after 18 UTC) likely resulted along with a complex event of simultanous flares on the eastern solar limb, beginning after 15 UTC: (images. SDO):






The proton flux values were rather low but meet a still active accumulation of protons and electrons form previous SEPs in the geomagnetic field -mainly the one that occured near summer soltice on June 18 and 21.that created a long term higher tension, that has weakened yet but has not really discharged yet

 Seismic activities indicating new magma movements increased especially around Hawaii islands, around Etna on Sicil as well as  below El Pinar at the South of  El Hierro, where about the Canary hot spot is presently situated:

M 2.9 - ISLAND OF HAWAII, HAWAII - 2015-10-02 17:44:47 UTC
( just one of numerous quakes registered near Hawaii today)

M 2.6 - SICILY, ITALY - 2015-10-02 12:04:18 UTC

After October 01- 2015, also  the earthquake swarm activities  near Puerto Rico resumed/ increased again those  occur since years and refer to  tectonic movements within the Atlantic ocean- likely   tensions caused by expanding magma rising up through the Midatlantic ridge as well as from  the Canary hotspot:

M 3.4 - PUERTO RICO - 2015-10-02 13:35:04 UTC

AUGUST 24- 2015



20150822/ AVCAN reports again higher surface seismicity , several larger rockfalls caused  surface damages on a road and water pipe near Sabrionosa/ El Hierro on Saturday morning- the first registered surface damage ,since January  2014, when the activity at the El Hierro hot spot had resumed. and continued since then:

( translated report from  thre AVCAN facebook  page)


Close the road of sabinosa for desprendimientos, iron.- The news is interesting because this detachment is reflected in the sismograma of several of the seismic stations of the ign with a signal very valuable in the closest ctab, giving us the exact timing of the detachment that occurred between 04:20 h and the 04:21 H.
The truth is that the shedding should be quite important to make this sign in the sismógrafo and provoke the damage they caused on the road and water pipe. Emphasize that it is an isolated incident and there is no earthquake prior or other causes earthquake-volcanic which can be attributed this event in the seismograms.( Enrique)


DOS ENORMES PIEDRAS HAN CAÍDO SOBRE LA VÍA ESTA MADRUGADA
Cierran la carretera de Sabinosa por desprendimientos
SERGIO GUTIÉRREZ| Para acceder al pueblo desde Frontera hay que desviarse por la vía de La Tabla y para salir de Sabinosa, se puede hacer a través de la carretera del Pozo de La Salud.
Dos enormes piedras impactaron de madrugada contra la vía lo que también ha provocado la rotura de una tuberia de agua, dejando al pueblo sin suministro momentáneamente.





Two magmatic quakes that occured below El Hierro and Teneriffe  on August 18 and 19  in a depth of  now  just 3 km. suggest that magma has risen up meanwhile 2 km higher  after the depth of the recent  measured quakes  continously  had risen to 5 km in June 2015:

AUGUST- 12- 2015:

TODAY: Notification on AVCAN facebook :


"Remarkable seismic swarm in Tenerife, very local to the station Maci, with events weak of a magnitude no older than 1 grade. We are aware that, since there was no consistency in the seismographs that allows us to see the ign in la gomera or in Gran Canaria. These events come unfold from 5:45 UTC (Jr)"

However: not anything like that yet in the IGN Earthquake register today:

AUGUST- 04- 2015



microquake activity  intensified at the end of July 2015. The most shallow quake was- surprisingly- due to IGN- registered near el Pinar on EL Hierro on 20150729 with a depth og 2 km (!!)- allthough  and nevertheless, IGN again  cannot say from  which depths the two quake on Teneriffe ( san Miguel) came from on 20150731 and 20150804:

 WHEN?

The shallow depth of these quakes again indicates that the magmatic intrusion still continues and  while the mantle magma  is by and by, slowly still but continously  coming higher and higher, a surface eruption of unknown kind and form remains the current long or short term perspective that becomes  more and more imminent.  Mnt. Teide, the seamount between Teneriffe and Gran Canaria but- as the  recent quake lets image - also El Hierro itself -seem to be- due to all semic data collected since Dec 2013- the  three most probable sites where this might happen.

Volcanism on the Canaries is really going on much more discrete than on any other known volcano and seems almost unpredicable . Measurements won`t indicate the exact time when this might happen. So just certain events on the surface such as steam eruptions, tremors or hightened temperatures ( propably going along with dying vegetation) that can be felt  in the ground will be  the only indicators for  such an uopcoming surface eruption of any kind and visitors an residents on the islands have to take  themselves the right decision at any time



TREMORS:

Tremor activity nevertheless is very low, what does not necessarely mean that no HOT MAGMA is present below the islands, resp the old caldera in between . Tremors-  at time of this update- however were RELATIVELY strongest on Gran Canaria:




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

JULY 07 2015



After the strongest proton event in the last years on June 18/ 21,Sinabung on Java had  reacted first with a  eruptions phase - almost permanently emitting pyroclastic clouds again since then .

Activity also resumed on  Canary hot spot with the most shallow earthquake since begin of the 3. activity phase in Dec 2013 , 4 km below sea surface beneath Teneriffe  already on June 18: But "El Discreto" still keeps what its name promises: so sign of any surface activity so far since the 3. and yet longest activity phase had begun in December 2013...( find more about that in my  blog of previous month) 

But after the protons of the stronger SEP on June 21 ( with a duration of 9 days and a highest value of 1.000 pfu likely the strongest in the last decade) again mainly went down along the  longitudes of the west American coast, the mean  measurable heat  effects from the Earth mantle ( the high speed protons create when entering the Earth s interior/ body along the geo magnetic field lines of the Earth) shifted to the Yellowstone caldera.

The Sun had been rather calm for more than a half year and thus hot spot activity resp.magma intrusion had also decreased all over the world: major eruption phases ended on Etna, lava emissions on  Kilauea on Hawaii had significantly  decreased as well as the activity in the Yellostone park had calmed down and was back almost to normal in the first half of June 2015...


: Magma however had some time to cool down and thus the new intrusion , the new but strong magma boost expectable  after the strong proton event on June 12´21 needed a while to climb further towards the surface.

But after June 30, the activity in the Yellowstone caldera then visibly increased as expected with more geysers opening up again and on the first of July 2015, the activity there was at the highest point so far, I yet could observe in the past years. If have daily made video  recordings of the activity from  the Yellowstone webcam, but just had not the time yet to edit that material  and to post it on youtube. Just to wait some more days helps also  to see,  whether  the daily increase of geyser activity observable since June 30 will further continue nor not...

JULY 07 2015:


NEW MAGMATIC QUAKES


Now on 20150706 and 08 also new magmatic quakes were  registered below Teneriffe, but now in deeper areas of 30 km on July 06 and 13 km on July 08.:
