Some of the islanders have said they cannot believe there has been not  one official statement.

They have been filling in the IGN questionnaire since yesterday and early this morning regarding the movements sounds and tremors being felt some have also mentioned strange smells and feelings of light headiness but nobody has had any reply from anyone at IGN or the government.

Sometime between 134 and 21 ka, the volcanic edifice of El Hierro Island, the youngest, smallest and westernmost island of the Canary Archipelago, grew unstable and its north flank collapsed seaward to form the 15-km-wide El Golfo embayment. Since this event, eruptions at El Hierro have concentrated at the base of, and directly on, the landslide headwall and have commonly involved peculiar ankaramitic lavas rich in clinopyroxene and olivine crystals. The most striking examples of such eruptive products are located at the prominent Tanganasoga volcano, where at least ten eruptive vents have produced a large bulge in the centre-west part of the El Golfo embayment. Lava bombs from the northernmost craters reach up to ~1 m across and show extremely high crystal contents of up to 50 vol. %. Loose lapilli deposits found on the slopes of the cones contain large, often intact clinopyroxene crystals that frequently reach 1.5-2 cm, with the largest found being 3 cm across. We analyzed the whole-rock and groundmass composition of the ankaramites, as well as the composition of phenocryst phases. Moreover, four clinopyroxene megacrysts were studied in further detail, with > 300 electron microprobe spot analyses per crystal. Results indicate that groundmass and co-existing olivine and clinopyroxene crystals approach chemical equilibrium in terms of Fe-Mg exchange. Core-to-rim chemical profiles in the smaller crystals (< 1cm) reveal relatively homogeneous compositions of intra-sample crystal interiors. However, steep normal Fe-Mg zoning is common in the outermost 20-40 μm of the crystals. In contrast, some crystals show reverse zoning towards the rim. Clinopyroxene thermobarometry indicate crystallization pressures of 700-900 MPa and temperatures of 1170-1220°C. The megacrysts show complex oscillatory zoning patterns, which, nonetheless, translate into modest chemical variations (Mg# = molar Mg/(Mg + Fetotal) = 76-80). We propose that the formation of Tanganasoga's ankaramitic magmas and clinopyroxene megacrysts is the result of a complex interplay between prolonged magma storage, regular influx of fresh magma and efficient crystal growth, fractionation and accumulation at upper mantle depth. The eruption of such dense, crystal-rich magmas probably requires forceful triggering, and appears to be facilitated after large-scale landslide events.

The IGN is impossible and on the other hand, there have been so many... that or I remember. Because as Elsa knows: each one is different.

007 SPECIAL NOTE PROCESS TRACKING VOLCANIC EARTHQUAKE ON THE ISLAND OF IRON. (23/03/2013 - 22: 30 h kuwait Canary 19:30 - UTC) in the recent earthquakes, the swarm moves farther to the West and begins to move to the South also, now these so strong earthquakes are directed back to the island, what a night... no coment (Enrique from Kuwait) http://www.avcan.org/?m=Mapas&a=mapa&mf=5489 to wear as a reminder, since it is very important, that to report that they have felt earthquakes of more 2.5, these IGN puts them in your list, where is provided to fill in the questionnaire: http://www.ign.es/ign/layoutIn/geofisicaCuesmaCuesmaTerremotos.do if still is not on the list, or it is noticing is not an earthquake, but vibrations, odours, deformations, anomalous animal behavior, smoke, spots, noises, or other things, then have to go and fill in the following questionnaire that has a text box at the end to put the sense ^ _-. http://www.02.ign.es/ign/layoutIn/geofisicaCuestionarioMacrosismico.do at 012 may report earthquakes or any anomalies observed by calling the number 012 (payment therefore is DIVERTED the call) or directly by calling the number which marks the 012 so we don't charge if we have national flat rate: 012 = 922 23 93 01.

In the evolution of the depth of the earthquakes, they tend to occupy an area of increased activity, extending especially towards levels more shallow in the final hours between 12 and 16 miles (Henry) http://www.avcan.org/sismica/graficas/G2273.jpg?t=1364067718

By the way, a note, the curve continues to rise and that way with these recent earthquakes... This is impressive, not loosen, it continues to accelerate, and rises approximately every 3 h, last was about 18:00 h, so the next should be around 9:00 pm and the next around midnight almost nothing, we'll see, cuidense much...

 have found this information taken in Volcanodiscovery today, seismic data are out of date, of course. : "Update sat 22:44 March 23." erremotos increasing in frequency and magnitude. The seismic swarm continues even increased intensity in magnitude media and frequency of earthquakes, as well as the armonico-volcanica tremor amplitude that is oscillating between upper and lower phases. This may correspond to a kind of "stop and go" behavior of magma moving, opening road through new cracks in the lower crust beneath the island. The location of the epicentres of the earthquakes, the supposed location of the current intrusions of magma, is now about 5 km off the Western tip of the island, already a depth between 10-17 km. Don't upload much depth, but this could change quickly. Today's earthquakes have so far:-155 earthquakes > mag 2 - including 15 between M3-3.5 earthquakes with magnitudes increased continue.The scenario of an eruption in the near future is becoming increasingly likely:-volcanic Tremor continues, suggesting magma still is moving laterally but above all for the moment to an area just north of the Western tip of the island. -Earthquakes continue to increased high-frequency and magnitude (more than 90 earthquakes of magnitude greater than 2, including 8 of 3-3.5 magnitudes up to today's date). Their epicenters have kept 14-16 km deep, mostly, with some events deep also. -The deformation of the western part of the island continues to grow, with vertical lifting, reaching about 5 cm in some stations in the western part of the island. The research vessel Spanish Roman Margaleff is underway to investigate the western area of El Hierro, and INVOLCAN is planning a survey of the land in the coming days. Its results will probably give more clues as to what is happening.

Avcan Comment Translated.

There is a sill is filled from deep and extending according to the contact surface between rust and the island shield.
-Mildew is less distorted at the edges, high, in the Centre of the island, sunk.
-The seismicity tends in at the time to ascend in the sense of soar, to the extent that we move away from the center of the island.
-Magma escapes when the sill reaches to break weaker crust on the edges of the island shield thin, weak and with lower pressure containment.
-Seal or valve "tanganasoguica" seems to be still intact until it ceases to be so, if the intrusion is prolonged in time and reaches to melt it by mere theater.
-A corollary of all this, is that there is deep seismicity of the mantle, by its viscosity, either there is too much in the center of island shield by its high resistance and for not being too intrusado for now, but yes, occurs to the edges of the island to the extent that the sill in its filling takes off and separates two slightly welded layers: the cloak and shield, formerly poorly United and now separated by fresh magma. Break this bad welding, produces the current seismicity.
