Vulkaanuitbarsting bij Canarische Eilanden #4

Update 20/08 – 13:12 UTC
We are currently in the midst of a slightly changing seismicity pattern. Why ? For the past several days we have seen a lot of (mostly weak) earthquakes at a depth from 10 to 13 km, but since yesterday we see more 20 km hypocenters. The deeper quakes are mostly more powerful. The deeper earthquakes are still located at the western tip of the island (June / July swarm)
These are the last 3 earthquakes :

Update 02/09 – 17:33 UTC
- Joke tells us that people living in Sabinosa and in other parts of the El Golfo bay are complaining about strange smells. This goes onfor at least a couple of weeks. ITER and IGN are told to take samples regularly, but the biggest complaint from the population is that nobody tells anything. Those following the events from the beginning do know that this comes not as a surprise to us. Most of the shallow 9-11 km deep quakes are centering in the El Golfo and Sabinosa area.

Update 12/09 07:45 UTC
- 5 earthquakes have been listed by IGN so far today. One earthquake was at a depth of only 6 km, not yet at a potential eruption level, but this is already the 3th shallower earthquake in 2 days.
- Deformations are still up and down with approx. the same values. Yesterday 2 cm deflating, today 2 cm inflating as one can see at the Prof. Sagiya graph below

Update 11/09 23:55 UTC
- And 5 more at the end of the day, which makes a total of 21 earthquakes today

Update 16/09 – 07:46 UTC
- Until 07:35 today, IGN has listed 73 earthquakes. Magnitudes vary from M1.4 (the weakest they are listing but there are hundreds more below this Magnitude) to M2.7. Maximum magnitude decreased a little bit from yesterday (up to M3.2).
- Focal depth remains the same (no penetration into shallower layers)
- Epicenter location is fairly stable (see image below and compare it to the last images yesterday)
- NO more (listed) earthquakes in the El Golfo bay at the 10 km depth layer.
- In line with what could be expected is that the deformations are up again.
- Frontera GPS station has moved North for about 1.5 cm and was also lifted with about 2 cm.
- El Pinar GPS station showed the same movement.
- Restinga GPS station moved a little eastward, did not move along his latitude axis and was inflated most of these 3 stations.
All these data were Ultra Rapid data coming from Prof. Sagiya, a GPS authority in Japan working at the University of Nagoya.
All the mentioned stations operate automatically, which means that nu human is needed to send the data to the computers of the University. Check PINA, FRON and REST stations here.

Paroxismo sísmico en El Hierro

NOTE AVCAN 100 - 14.09.2012 -23:59 h peninsular. - EVOLUTION AND FOLLOW THE EARTHQUAKE SWARM IN-volcanic island of El Hierro. 100 notes from the June 24 earthquake, volcano monitoring eb El Hierro and just today arreón, took more than 40 earthquakes located and unlocated hundreds, come with a fledged revival of the volcanic system that makes you again today

Volcanic Islands, and on multiple sites, not just one, today we see more clearly, two swarms of Hierro volcanic earthquake-mismatched or depth or position ... The first in the Gulf area against Sabinosa about 8 to 11 km depth, and the second in the Gulf but also under the Border area - the Llanillos, deeper about 18-21 km. Watching the hundreds of CHIE earthquakes detected and located just on the seismogram, is the deep system which is generating so much stain and earthquakes in the apparatus, for the times and depths, one thing is clear, there is again a new intrusion of magma at depth as passed on 24 June ... almost anything ... and the worst is that we may have more upside seismicity the next few days .. and of course we'll see deformation and gases that will follow this. updated on the map today, we earthquakes located 43, 12 and 7 before yesterday yesterday, although in the spectrogram and CHIE seismogram are many more, with more a hundred per hour in the last hours giving a spasmodic tremor deep where it is difficult to locate them and have not been located and much besides microseismicity. In the first part of the day are located in shallower swarm area of the Gulf but the second part has been in the deep trend has been reactivated in the last hours to move the seismicity to the S - SE towards Restinga. ... The magnitude of the earthquakes today reaching up to 2.8 for the deep system and 2.6 for the surface. now as when the previous eruption senses besides earthquakes, vibrations are continuous in areas such as Pinar, La Restinga, San Andres, in several urban parts as Tigaday Frontera, Los Llanillos, Las Lajas, Las Toscas, Los Mocanes, and more sites as tips, Sabinosa, Table, The Mocanal, Tamaduste, La Caleta, and even the Parador on the beaches. Some sites also come with noise and bumps and tremors are detectable in the liquid from a bottle in most of the island, as a tremor, surely by the continuous stream of earthquakes that are suffering the island. As odors have not been reported. As for the strange behavior of animals None reported. Curiously enough this morning they received reports Liara all this noise and vibration from other islands, particularly from Palma and Tenerife, which occurs prior to the reactivation in Iron, the less curious. now with so many earthquakes, Luis message reaffirmed very recently of the previous post, inviting everyone to stop by the utility AVCAN web animation (Henry).

SPECIAL NOTE 100B, monitoring the seismic-volcanic activity of El Hierro, after a rough night, seismically speaking, the system moves, is pressurizing (the earthquake of 3.1 on the advice, which actually may have something stronger if any continuous pressurizing and clear, this indicates that it has not yet found a way out, so it is down there looking for her.

As for the map of earthquakes, apart from making a perfect ball indicating that a swarm produced by new magma intrusion deep seismicity seems to be moving towards the SSE, towards Restinga area, and are accumulations in multiple alignments of earthquakes in the Gulf in directions NNE - SSW more or less inclined NS in the south of the swarm, WNW-ESE, etc.

SPECIAL NOTE 100C, monitoring the seismic-volcanic activity of El Hierro, is very busy, seismically speaking, the system moves, is pressurizing (the 3.2 earthquake a few hours ago on the advice, you may now have one more thing continuous pressurizing strong and clear if this indicates that has not yet found a way out, so it is down there looking for her.

On the map the simicidad, today we have been 108 located, almost all greater than 2.0 and the fact is that in these last hours the seismicity is despalaza SSE towards the Restinga on an axis NNW - SSE from the Gulf as another eruption, but this time points to pass just below the town of La Restinga .. and maybe even El Pinar.

NOTE 101 AVCAN - 15/09/2012 -23:15 h peninsular. - EVOLUTION AND FOLLOW-VOLCANIC EARTHQUAKE ACTIVITY IN THE ISLAND OF IRON.

We and took over 130 earthquakes located today and many hundreds more unaccounted for that is clearly visible in CHIE as earthquakes chained in some cases become attached as a continuous tremor, better known as spasmodic tremor to be too deep. Of course, for which you have doubts, this is a full-fledged revival of the Iron volcanic system that makes you current again volcanic Canary

Today the first swarm shallow no sign obscured by the noise of the second and the updated map of today, we located 131 earthquakes, 71 yesterday and 12 the day before yesterday, that apart from making a perfect ball about 18-22km, indicating that it is a swarm produced by a powerful new intrusion of magma deep seismicity seems to be moving towards the SSE, looking very well in recent earthquakes blue ... to the area of La Restinga and Pinar, and accumulations are earthquakes in various alignments in the Gulf in directions NNE - SSW more or less inclined NS in the south of the swarm, WNW-ESE, etc. The magnitude of the earthquakes continued pressurizing, today the first 3.1 and then up to 3.2, while for superficial system still at the top of 2.6.l.

Today as when the previous eruption besides tremors caused by earthquakes felt in most of the island and talk of all cliques stray vibrations are ongoing in many areas such as Pinar, La Restinga, Tamaduste, La Caleta, San Andres in several urban parts as Tigaday Frontera, Los Llanillos, Las Lajas, Las Toscas, Los Mocanes, and more sites as tips, Sabinosa, Table, The Mocanal, Tamaduste, La Caleta, and even the Parador on the Beaches . Some sites also come with noise and shock, having been heard several in the Gulf and the tremors are felt in the liquid from a bottle in most of the island, as a tremor, surely by the continuous stream of earthquakes that are suffering the island. As odors have not been reported. As for the strange behavior of animals None reported.

There have also been reports of some earthquakes, as well as noise and vibration from other islands, particularly from Palma, La Gomera and Tenerife.

I remember all that is very important if you feel any of this, you should report it to IGN to have documented what felt besides the importance of monitoring should be opening an area eruptive mouth .. is very important. (Enrique).
