Hi Fifi it is so interesting and have learnt so much about Mother Nature.

No the webcams are not reinstated I thought by now this would have been a priority.

Involcan are reporting that CO2 is above normal.

Roger P Frey has posted this on twitter.

Up to 11 UTC 33 >/= M3 earthquakes on #ElHierro 4 felt by population. Due to Gutenberg-Richter law probability of > M5 rised much.

Its an interesting theory.

Avcan have reported in the Orchilla area deformation is 10 cm.

The deformation is very important, more than 10 cm in Orchilla according to IGN GPS data as of INVOLCAN-GRAFCAN.

Statement from Involcan regarding the CO2 readings.

..INSTITUTE VOLCANIC CANARY ISLANDS
"The following graph can see the temporal evolution of the diffuse emission of carbon dioxide by El Hierro Island volcanic system dede July 2011 through March 26, 2013." The average estimated value for this parameter is obtained taking into account all scientific campaigns conducted by the ITER volcanic Group since 1997 and is located in the order of the 345 tons/day. The rate estimated for the scientific campaign recently after diffuse emission of carbon dioxide is 1684 ± 72 daily tons. The non-existence of data on this parameter during the time periods linked by dashed lines is due to the lack of resources to have maintained a permanent presence of the INVOLCAN in El Hierro since last April, 2012. The current rate of carbon dioxide emissions exceeds the threshold + 1σ of the range of values considered normal for the diffuse emission of carbon dioxide for the iron. This parameter reflects and confirms the current rally in sismovolcanico of this recovery process magma that is experiencing the Meridian island."..

According to this comment the deformation is 20cms in the El Julan area .

Comment posted on the Avcan FB page

According to Nagoya gps deformation that shows is an elevation in the Julan of 20 cms, in Faro 17 cm, border 13 cm and in Sabinosa 13 cm. is it right?

Ultimas noticias desde Sabinosa: el seísmo de hace dos minutos ha sido fuerte y muy largo, pero lo extraño ha sido que el movimiento ha sido en redondo (ni de lado a lado, ni de delante hacia atrás) Me ha movido en redondo. Me he quedado pasmada. Dios mio! estoy oyendo piedras caer justo detrás de mi casa.


Latest news from Sabinosa: the earthquake of two minutes ago he was strong and very long, but the strange thing was that the movement has been in round (or from side to side, or front back) has moved Me round. I was stunned. My god! I'm hearing stones fall right behind my house.

Gracias Elsa y gracias a todos. Os cuento: He oído piedras grandes caer (yo diría, justo detrás de mi casa, pero no, han sido por encima de La Breña, como la otra vez) He encontrado a mi vecino y me ha dicho lo mismo, lo del movimiento circular. El cas...See More

Thank you Elsa and thank you all. I tell you: I hear big rocks fall (I would say, right behind my house, but, they were not above La Breña, as last time) I found my neighbor and he has told me the same thing, it's circular motion. The case is that when I'm back to enter and I sat down at the computer, light is going and we were without wifi, without phone and see a posh. Luckily, there is luna. The light is now restored and appears to be a truce.

Comment recently posted on volcanocafe :

I know these are only tiny but they are directly under the island and very shallow. I hope they aren't the start of something.

They are getting stronger all the time Jand....a 4.6 this morning....that must have caused further landslides. Thanks for the videos. I am loving following it again. :)

Too much to report there has been a really strong earthquake this evening more rockfalls and talk of large waves after the strong earthquake this evening. Whether the large waves were due to the EQ has not yet been confirmed.

..In the curve of cumulative released seismic energy of all earthquakes from June 2011, is since counting all the earthquakes, this system has released more energy than anyone we've had to date, this system is going to another level, is much larger than the previous ones, and shows it with one greater than previous cases (Enrique) seismic force..

..019. SPECIAL NOTE PROCESS TRACKING VOLCANIC EARTHQUAKE ON THE ISLAND OF IRON. (29/03/2013 - 22:00 h - 19:00 Canary - UTC kuwait) What a day, 4.7, 4.6, 4.5. etc. and carry 12 quakes of more 4 and some have closer to that value, and not finished the day, indeed is in the updated map that swarm continues moving toward the SW-SSW and seems that continues to turn South. In what refers to the release of seismic energy, today has released more energy that all swarm sanjuanero November 2011 or 2012, and in fact with the cumulative curve continues to rise and also makes it following a lognormal pattern, i.e., continuous reactivation and increasingly releases more energy seismic, increasing exponentiallyI can only say that if this is so, we are increasingly more away from that stand and more about break somewhere..

- Mid-Strong earthquakes started at 19:10 are continuing at the time of writing, as again, being felt by the population of El Hierro. We will keep you, as always, updated.
- Earthquake depths are descending, as magma keeps pushing from below.

2013-03-29 18:51 UTC
- If you cannot reach IGN, you are not the only one ! We neither. Probably a bandwidth problem (Back live again)
- a relatively calm period at this moment
- 133 earthquakes listed by IGN today
- The M4.7 was felt as a MMI III intensity (weak shaking) at the island. The hypocenter was measured at 20 km

Comments of more rockfalls near Sabinosa.

Los de las siete de la tarde se han notado muy fuertes en Sabinosa y ahora siempre con desprendimientos en el risco de  La Breña y carretera de Arenas Blancas.

Of the seven in the afternoon have noticed very strong in Sabinosa and now always with detachments on the cliff of La Breña y carretera de Arenas Blancas.La Breña and white sands road.
