This is very interesting will need to be translated .

Part translated: As we can see in the example from the 30th of November is a seismic signal that is characterized by maintaining amplitude constant for a long period of time, with a spectral content focused on frequency bands relatively narrow (3). In the same image (approx. 40 min) we can see the difference with a tectonic earthquake, which occurs in all frequencies and is of very short duration. The earthquake had a magnitude of 2.8 and it was located by the IGN in the sea between Fuerteventura and Gran Canaria  (4).

Volcanic tremor is associated with the movement of magma or other fluids on the inside of duct and usually, but not always, as we shall see, precedes or accompanies volcanic eruptions.

The first time that volcanic tremor was recorded on the island of Tenerife was during the unrest of 2004-05 (5). However, on that occasion it was accompanied by a profusion of earthquakes of all types: volcanotectonicos, long-period events, hybrid(5); there were also increases in volcanic gases diffuse emission(6,7)variations in physicochemical of the aquifer parameters;(8); and gravimetric alterations(9). According to various publications the unrest of the 04 could be due to an injection of magma that was in the basement, followed by a migration of volcanic gases. The interaction of these gases with the hydrothermal system might be the cause of the tremor  (5.9).

This maybe to do with the increased EQ activity in Southern Spain.

Will need to be translated.

,,More than 500 troops participate in a mock Quake in Torrevieja .

Torrevieja is the scene of a mock terratrémol hui in the framework of the Special Plan against the unfortunate seismic risk of the Valencian Community. 500 troops participate in this simulated magnitude 5.5 Quake on the Richter scale in an area that was desolated by a tidal wave in 1829,,

SOME earthquakes in EL HIERRO, these last hours, there have been some seismic movements, although 1 to N in the sea, are of low magnitude, barely perceptible by the population with several small earthquakes located yesterday afternoon and last night in the central area of the island of el Hierro in the area of the Gulf, specifically 3 South of Sabinosa, 2 under border and 1 into the sea in the area of the ends at a depth between 10.9 - 12.5 km.

Have a look at this video filmed February 2013  at 09:20 there is some discussion on the internet about the bubbles seen coming out of the ground .

Could they be something to do with the volvanic activity in El Hierro???

This has just been posted on the Avcan Facebook Page.

Muy importante tener en cuenta lo que nos recuerdan Victor Manuel Tapia Zamora y Luis Francisco López Peña. No hablamos de erupción sino de la probabilidad de una nueva intrusión magmática y tampoco hablamos de tremor armónico sino de espasmódico.

Very important to take into account what we remember Victor Manuel Tapia Zamora and Luis Francisco López Peña. There are eruption probability of a new intrusion of magma and not talk about harmonic tremor but spasmodic. In any way, we are in an alarming situation, but it is necessary to remember the rules of self-protection and be attentive to any communication or request made by the authorities.

- 7 new earthquakes since the 17:39 UTC update
- People following this report longer than today do know that IGN is only listing the stronger earthquakes during seismic crisis like today. In reality there are far more earthquakes than those listed by IGN.

001 SPECIAL NOTE PROCESS TRACKING VOLCANIC EARTHQUAKE ON THE ISLAND OF IRON. New seismic swarm in the island of el Hierro in the marine area of the Gulf opposite Sabinosa to 16 - 22 km, which has been preceded by an enjambrito in the central area of the island is past midnight to 10 - 12 km. At the moment carry 38 localized earthquakes, (almost nothing with which we had these past months) Although in the spectrogram many see more and thing far from diminishing, seems to increase, with stronger earthquakes, indicating a process of intrusion volume, possibly centered in the area of Sea North of Sabinosa, which is where more earthquakes were located. Now wait for the strain data to confirm it. and also will need to confirm whether continuous intrusion, pressurized and increasing the magnitude of the earthquakes as they pass the hours/days... we nothing remains, we will see (Enrique from Kuwait)
