MAY 29-2016: CALDERA CLOSE TO ERUPTION?

Magma has reached a level of around 4 km below sealevel within the caldera -mainly between Teneriffe and Gran Canaria and is still on the rise.
( I dould not copy some previous events with several magmatic quakes from a depth of 4 km. But the latest event list shows even that magma rose in one wek 1 km higer and is therefore rapidly further rising. I also don`t want to paint something morre black as it is, but all these data  show that we might NOW REALLY be shortly before a larger surface eruption, that-  as I personally mean- could become a catastrophic event:

MAY 10-2016:

At begin of May 2016, a new serial of  earthquakes from shallow depth occured between Teneriffe an Gran Canaria mainly near towards the eastern coast of Teneriffe.
The latest one just occured on the day of this update and  had a magnitude of M 3.3. IGN has not published the depth of this recent  quake , which is therefore still unknown:

The previous one on May 7 had a depth of just 3 km, which sets a new mark as the most shallow likely magmatic quake since begin of this 3 activity phase end of December 2014.

At all three low magnitude qaukes from 6, 9 and 3 km depth indicate something is going on there. Since solar SEPs ( proton events) have decreased significantly after the last 11 year sun spot maximum in 2013, also hotspot activity worldwide has decreased.

Proton events with their subsequent electron accumulations in the Earth`s magnetic field  charge the earth with lot of electric energy that is effective for month and even years  in different forms of activity , Though SEPs were much less in 2015 and even less in 2016 yet,  other types -socalled filament eruptions - still  eject mainly proton  charged material ( in DC definition  "negative" charged) from the Sun`s surface to the earth what each time leads to minor and stronger geomagnetic storms .

But there seems not to be an effect to volcanoes by these filament eruptions . However-.- activity on all important hot spot points globally also decreased since the earth got now first time since 3 years time slowly to cool down again .

Yellowstone, Etna, Sinabung , Kilauea have returned to normal activity and the water level in white island caldera on New Zealand dropped for two meters following the decrease in  global hot spot activity- so reports Brad Scott for geonet that monitors the volcanoes in the Southern Pacific and near Australia, "while the volcanoe is still  at unrest":


White Island Crater Lake level drops, unrest continues

While magmatic inflation leads logically to an equivalent subduction process elsewhere, expanding magma that once rose up from the mantle , while creating immense forces that inflates / lifts up entire landscapes,  islands or mountains cannot flow back again into the earth mantle and therefor deformations by magmatic inflation are  unlikely to receed again. However some contraction effects , when magma cools down near the surface can surely create/ leave   holes thoswe  particularly could  collapse .

 El Hierro also does not show any sign to sink back to the level it was prior to the third activity phase beginning in end of December 2014 . With the main magmatic intrusion following soon after the island of El Hierro has been lifted up for about 2- 25 cm.Since February 2015 the magmatic intrusion continued with minor strength:

Its just: that I  don`t have the experience, to say what happens next and whether  these shallow quakes indicate such a minor collapse by colling donw magma or: that magma would still rise upofurther . So-I would strongly recommend to observe closely  the quake  activity then next time .

The (for me surprisingly) increase in quake activity  again at begin of May 2016 after month fo tranquility should be taken seriously.
