Update 28/06 07:55 UTC
- At least the people of El Hierro must have had a good night sleep as the strength of the earthquakes decreased seriously the last 7 hours. But only the strong earthquakes were more or less silent at night.
- So far today IGN has listed 39 earthquakes since midnight, a little less than the preceding days, but still a high number.
- Harmonic Tremor has restarted strongly since 05:35 this morning, showing us that the volcanic process is still continuing strongly. As we have experienced the last couple of days, the current HT may refer to a new migration of the epicenters
- The strongest earthquake since midnight was a M2.8 earthquake. NO earthquakes since midnight have been marked as felt by the people. At ER we think that Felt or no felt indications are far from reality as most people do not indicate slight tremors anymore after having experienced stronger ones. Aftershocks in general are less documented. Only nations like Japan, USA and New Zealand are drilled to report whatever they have felt.
- The depth did not show a lot of difference since midnight with values in between 17.6 and 22.9 km
- The epicenter of the earthquakes since midnight remains the El Julan La Dehesa area of the island
- We certainly expect more earthquakes to come today as the process continues in full strength.
- What can change the process fundamentally ? Our readers should watch the following elements in the current process with more focus than the rest : Depth of the earthquakes (changes towards a depth of 15 km or less can be triggers of new events, sudden change in the strength of the earthquakes, the locations of the epicenters (these locations are important in relation to the conduits of the recent eruption)

DISCLOSURE NOTICE INVOLCAN

In the attached image you can check the movement experienced by the GPS station located in Valverde. In the same motion can be seen clearly from the northeast, with an eastward shift of nearly 1.7 cm, and northward nearly 2.

Confirm and emphasize the horizontal and vertical displacements observed by GPS network Canaria (ITER + + GRAFCAN Nagoya University) operating Volcanic Canary Island Institute under the direction of Dr. Takeshi Sagiya (Professor of Nagoya University and Scientific Collaborator INVOLCAN)

These data confirm feformación a process of movement of magma underground, and the source responsible for this deformation is in the central-western part of the island of El Hierro in conjunction with data from recent seismic activity.

The displacements recorded during these last days are real and much faster than those observed last year 2011

Update 28/06 12:26 UTC
- The Oceanographic vessel Hesperides has been announced to arrive soon at the El Hierro waters. What the ship exactly will do is unknown (analyzing sea water looks evident to us) as the bathymetry will not have changed since the first eruption stopped a few months ago.
- Yesterday we have cut a big chunk from our main article. These parts are now saved in part 44 and 45 of the El Hierro volcano eruption history. The links to all the preceding parts can be found at the bottom of this page. We will soon cut another part of this page as it is reaching a critical size to be easily consulted by people with limited bandwidth like Colin.

Gister zijn een boot en vliegtuig op verkenning geweest onder El Hierro.
Hier de route die is afgelegd.

Update 28/06 – 21:50 UTC
- Everything looks rather normal today and people get used to the present conditions. Less strong earthquakes than yesterday bring a king of relief to the living conditions
- The process is however continuing just like the preceding days. IGN has listed 164 earthquakes so far, less than yesterday but still en enormous number.

Update 28/06 – 20:24 UTC
-Thanks to ER readers Sissel and Mafl who gave us both routing informations of the SAR aircraft and the Hesperides ship, we were able to see in the public domain the routing of both the aircraft and the ship.
Wat we earlier described as probably shipping related is not so sure anymore after gluing the 2 pictures together. It is of course normal that the authorities will not publish every move they are ordering in their research.
We also checked the NASA satellite image today, but it was to hazy to trace eventual discoloring . The common researched area is approx. 20 km to the south of La Restinga.
After some Ocean depth checking in Google earth, we found out that the submarine volcano cone were the plane and ship were circling is at a depth of 2000 meter (we know that that is not accurate, but it gives a clue of how deep we expect the volcano or seamount to be). Maybe todays flight and ship route were only meant to do some long planned research which has nothing to do with the current activity.
Update : As we were intrigued by this story, we remember an issue which occurred on October 10 2011, just before the sea at El Hierro started to color green. This is the text we wrote on October 10 (part 2 of the El Hierro story ) :
Following the Spanish Newspaper El Mundo, a small submarine eruption has taken place 7 km out of the coast. The eruption occurred at 1200 meter below sea level. The eruption took place in the Las Calmas sea to the south of the island at 10.43 local time (09:43 UTC). We expect an official statement soon.
The news comes from 4 boats presently navigating in the Las Calmas sea.
- The present conditions are however totally different than on October 10 (earthquake parameters). Another difference is that todays action took place at approx. 20 km out of the coast.

In the attached image you can check the hypocentral evolution of earthquakes in the island of El Hierro since last July 2011. The same can be checked as there are two periods of clear tendency to make them deeper, and the absence of shallow earthquakes in this phase.

The permanent GPS network INVOLCAN instrumental movements continued to show abnormal El Hierro

These ground deformation data "not perceptible to people," confirms a rise in magmatic reactivation under the island of El Hierro

The Institute of Volcanic Islands (INVOLCAN) reports that continue to be recorded anomalous horizontal and vertical displacements in El Hierro in the Canary GPS network operated by the INVOLCAN under the direction of Dr. Takeshi Sagiya, Professor of Nagoya University and Scientific Collaborator INVOLCAN.

During the last 4 days to confirm the registration of a horizontal shift to the Northeast (4.4 cm) and as an offset in the vertical (elevation of 3 cm) in the GPS station WNBF (http://www.seis.nagoya-u.ac.jp/sagiya/canary_gps/FRON.pdf) located in the City of La Frontera and a horizontal shift to the Northeast (4.5 cm) and a shift in the vertical (elevation of 4, 5 cm) in the GPS PINA located in the City of El Pinar (http://www.seis.nagoya-u.ac.jp/sagiya/canary_gps/PINA.pdf). By contrast, in the GPS VALVE, located in the building environment of the Cabildo of El Hierro (http://www.seis.nagoya-u.ac.jp/sagiya/canary_gps/VALV.pdf), no observed shift in the vertical, but horizontal displacement to the northeast (2.6 cm) over the last 4 days.

These deformation data "not perceptible to people," confirms a process of movement of magma beneath the island of El Hierro, and the source responsible for this deformation is in the central-western part of the island of El Hierro in conjunction with the recent seismic activity data. The movements recorded during the last 4 days are real and much faster than those observed last year 2011.

From January to June 2012 were recorded displacements of less importance, but still significant, the GPS stations located in Valverde (VALVE, east), La Frontera (WNBF, shootings) in the Restinga (REST, to the southeast and elevation), El Pinar (PINA, to the east) and Sabinosa (SABI, began to move slightly to the north).

The Red Canary GPS is a network of 35 permanent geodetic instruments GPS stations whose ownership depend on different agencies and administrations but perform a joint commitment to contribute to the improvement and optimization of geodetic software for volcano monitoring in the Canary Islands and has the ability to detect any ground deformation associated with volcanic phenomena in depth. In the case of El Hierro, Canary GPS Network currently has 7 stations ITER differential GPS (2), Nagoya University (4) and GRAFCAN (1).

At present the data on the geochemistry INVOLCAN is getting applied to volcano monitoring of the volcano island of El Hierro is delimited to the registration of permanent instrumental network geochemistry in the Island of the Meridian with 5 stations geochemical ITER. Therefore, at present it is unknown which is the amount of carbon dioxide and emission levels of helium-3 that the emerged part of the volcano island of the iron being emitted to the atmosphere; geochemical parameters of interest to evaluate both the current upsurge in magmatic reactivation under the island of El Hierro.

The emission of carbon dioxide that is being registered in HIE01 geochemical station, located at the intersection of the three main volcano-structural El Hierro, does not reflect outliers moving average values ​​were recorded daily during the last 7 days of 4 grams carbon dioxide per square meter. Nor are occurring outliers emission of carbon dioxide in HIE06 geochemical station, located in the area of ​​the volcano sumital Tanganasoga, whose record of daily moving average values ​​over the last 7 days is 0.8 grams carbon dioxide per square meter. In both stations are not being detected geochemical emissions of hydrogen sulfide.

These results have been obtained thanks to MAKAVOL project "Capacity Building of R & D + i + d to contribute to the reduction of Volcanic Risk in Macaronesia (MAC/3/C161)" which is being co-funded by the program Transnational Cooperation European Union Madeira-Canary-Azores (MAC 2007-2013), and the collaboration of the Research Center for Seismology, Volcanology and Disaster Mitigation, University of Tokyo (Japan), GRAFCAN (Canary Islands Government) and as of the Island Councils of Tenerife and El Hierro and the municipalities of La Frontera and El Pinar.

The Institute of Volcanic Islands (INVOLCAN) or National Center for Volcanology is an institution demanded unanimously by the Senate (2005), Parliament of the Canary Islands (2006) and House of Representatives (2009) which calls for an urgent and pressing to the General Administration State and the Canary Islands and the Island Councils to the joint commitment of all human and technical resources that various intended for scientific management of volcanic risk in Spain (say Canaries, the only volcanically active region volcanic country risk) without incurring the loss of ownership of their resources and in order to ensure effective coordination and efficient to reduce volcanic risk in the Canaries. To date, the Cabildo Insular de Tenerife is the only administration that has been involved with this unanimous decision of the legislative chambers in this country.

From INVOLCAN is recalled that the official information on the level of alert to adverse volcanological phenomena which is output from the communications of the Special Plan of Civil Protection and Emergency Response for Volcanic Risk in the Canary Islands (PEVOLCA) .

- Another strong M3.6 earthquake just occurred at 12:51 UTC a little to the south of the lighthouse. The depth was measured at 18 km. This earthquake was (of course) felt in parts of the island.
- Seismicity started to increase approx. 20 minutes earlier
Bevingen verplaatsen zich wel langzaam meer naar het westen lijkt het

Gister avond en vanacht was het ook onrustig.
Heel wat boven de 2.5 en een 3.8 en 4.2
niet echt rustig.....

Update 03/07 07:34 UTC
- Deformation statistics from the University of Nagoya in cooperation with Involcan are showing a strong decrease in Ultra Rapid values in the stations of Sabinosa, Pinar, Frontera and La Restinga. The numbers are showing a reverse effect than last nights earthquakes would have assumed.
- 71 earthquakes so far today, the strongest one being a M4.2 at 2:31
- hypocenter or focal depth range remains as it was, at 18 to 21 km in average. No shallow quakes anymore.
- activity has calmed a lot the last several hours, but earthquakes still occur at normal (whats normal ?) values of M+2
- the real number of volcanic earthquakes (including the weak ones) is far greater than the 71 mentioned above. How to see that ? Take a quick look at the CHIE graph and count the vertical out-swaying lines, and thats only a portion of it!

Update 03/07 15:41 UTC very interesting Press Conference
IGN expects new strong earthquakes (up to M4.5-M4.6) for the next 7 days. This has been said at a press conference today. Pevolca does not have the intention the meet soon again if only these earthquakes are continuing as this is expected from now on. Pevolca asks the population of El Hierro to be ready for whatever eventual urgent communication which Pevolca may decide. The Grupo de Emergencias y Salvamento (GES) will be at El Hierro to reinforce the local groups, this to be prepared for whatever crisis to come.
María José Blanco (IGN) has said that an eventual eruption at the present seismic center (Las Calmas sea south of the lighthouse), where depths of the hypocenters are still measured at 20 km, can be excluded at this moment. She said that it also lasted quite some time last time before an eruption took place. The epicenters of the earthquakes had to migrate more than 20 km to the south before the magma found his way up. María José Blanco also said that an eruption on land can be excluded at the moment but that IGN follows up the situation very consciously as all the events are going much quicker than during last years eruption. (compiled by ER from a number of local press reports like Diario El Hierro)
- Already 123 earthquakes so far today

INVOLCAN DISCLOSURE NOTICE: EVOLUTION GPS

After exhaustive analysis during the last hours of GPS data, Dr. Takeshi Sagiya, Professor of Nagoya University and Scientific Collaborator INVOLCAN, informed the group that the fall INVOLCAN observed in the GPS antenna of El Hierro, also been observed in other antennas located outside the island of Meridian, which coupled with little or no variation in the horizontal component leading to suggest that the data reflected by the GPS is affected by external effects, which could be related to tropospheric interference.

Very important Update 03/07 – 23:55 UTC
A report from the GSC (Communication department of Canary Islands) has revealed that a helicopter survey unit has noticed a (small) jacuzzi and a white stain at coordinates 27º 4.573” N y 18º03.761” W in the Las Calmas sea approx. 180 meter out of the coast. The images which have been taken by the helicopter will now be analyzed by the IGN scientists. A new flight above the zone is planned for tomorrow.
- Nobody is sure at this moment whether this picture really reveals a new vent or shows just some currents. The similarity is at least what we used to see as colors and as water agitation during the 2011 eruption.
Jon Frimann (Icelandic volcanoes blog) writes an interesting comment which we share : Dike intrusions can happen with and without harmonic tremor. Dike intrusions with harmonic tremor happens mostly at places where conduct is well established. That is not the case now. So I would not trust any signs for harmonic tremors just yet. Harmonic tremor pulse might be seen few hours before the eruption starts. Given my experience and what I did see during Eyjafjallajökull volcano eruption in the year 2010. Given the amount of earthquake activity. I am assuming that some of the magma has reached less depth in the crust without making many earthquakes at present time. The reason for that is magma has easier time to make the rock soft at less depth. Soft rock means few to no earthquakes. How this plays out is all big question that currently nobody has an answer to at the moment. (Thanks to Ian Carson for informing us)
- Below another picture of the detected stain and small jacuzzi (the picture above in natural colors – in the picture below we have increased contrast and sunlight) (All pictures courtesy GES).
- Why all these maps below ? : we tried to use the coordinates as given in all the media, but we could not trace the location which coincides with the picture. Finally we decided to scan the southern coast and we tried to detect the trails along the coast. Once that being done, the google maps matched with the picture.
