Over 150 earthquakes were recorded on the smallest of the Canary Islands during Tuesday prompting officials to evacuate some local residents, shut El Hierro’s main tunnel, and close local schools.
At least 20 earthquakes, exceeding magnitude 3.0 on the Richter Scale, have been felt by local residents during the last 24 hours. The most recent earthquake, which measured 3.4 magnitude, was recorded just off the southern tip of the island at 07:04 am Wednesday.
The rise in seismic activity last night prompted the Spanish Civil Guard (Guardia Civil) to advise almost 50 residents of the municipality of La Frontera to leave their homes because of landslide fears.
Plans are also underway to evacuate more of the island’s 10,000 residents, according to Canarias7.es. The newspaper reported that two units of the Spanish military’s emergency intervention unit (EMU) will depart nearby island Tenerife this afternoon to assist in the possible evacuation of hundreds of El Hierro residents.
Meanwhile, the island’s main tunnel (Tunel del Golfo), which links Frontera to Valverde, has been shut forcing motorists to travel across the 280-sq-km island via a mountain road. The Cabildo de El Hierro also has ordered the closure of schools on Wednesday.
Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793. The eruption lasted approximately one month and produced lava flows.
The Canary Islands Government commenced an in-depth geological survey of El Hierro earlier this month in an effort to determine the source of an earthquake swarm. The Government raised the volcanic risk level to ‘Yellow’ on Sunday, the highest alert status since an unprecedented earthquake swarm commenced in mid-July.
The unprecedented seismic activity commenced on 19 July (the activity was first reported by iWeather Online on 26 July). In excess of 8,200 earthquakes have been recorded up to Wednesday, 28 September 2011.
Up to last weekend, the majority of earth tremors ranged between 1 and 3 magnitude. However, the majority of quakes are now registering between 2 and 4 magnitude and are occuring at depth of 14-17 kilometres, according to the National Geographic Institute (IGN).
Speaking to the El Pais newspaper, volcanologist Juan Carlos Carracedo suggested that an eruption on El Hierro would “not be a major surprise”. He explained: “It is the youngest of the Canary Islands. There is a ball of magma which is rising to the surface and it is stationed at the limit of the earth’s crust. At the moment we do not know if that ball of magna will break the crust and cause an eruption.”
IGN Director, María José Blanco said that any eruption on El Hierro would most likely have a “low explosion value”. He added that an imminent eruption is unlikely.
In the meantime, the frequent and increasingly intense earthquakes being felt throughout El mlrro are unlikely to appease the residents of and visitors to the tiny island.

quote:53 evacuated as seismic activity continues in Spanish island
MADRID (Xinhua) -- A total of 53 people were evacuated from their homes on the Spanish island of El Hierro on Tuesday night due to seismic activity in the area.
The evacuees were sheltered in school buildings or other relatives' homes in safe areas.
In recent days, there has been increased seismic activity, raising fears of the first volcanic eruption on the island since 1793.
There have been over 8,000 tremors registered since July. Although the vast majority of them have gone unnoticed by inhabitants, they have recently increased in intensity, tremors last week measuring 3.0 and 3.4 on the Richter scale.
The threat of volcanic activity on the island was raised from green to yellow for the first time in recent history and 32 more tremors were registered on Monday, the strongest of them being 2.0 on the Richter scale.
El Hierro, part of the Canary Islands in the Atlantic Ocean, is situated off the west coast of Africa and has a population of around 10,000. The recent seismic activity is thought to be caused by a ball of magma -- or molten rock -- pushing upwards beneath the earth's crust.
Instead of having one large crater, the volcano on El Hierro consists of 250 smaller craters. If an eruption did occur, lava would escape from these vents and flow towards the sea. A single explosive event, such as that experienced in Mount St Helens in 1980, is not expected by geologists.
This May, the Spanish mainland was hit by an 5.1 earthquake that took 10 lives and devastated buildings in Lorca in the south-west of the country.
quote:Scale of earthquakes seems to calm down
The Canary Islands Government and the Cabildo de El Hierro have decided Wednesday night that the schools of the island on Thursday resume normal activity, in view of recent scientific reports indicate that the scale of earthquakes seems to have slowed and has entered a stationary phase.
However, it will be closed to traffic, risk of landslides, the tunnel that connects the island's capital, Valverde, to the valley of the Gulf (north), the most affected by earthquakes, as reported by the director general Security and Emergency of the Canarian Government, Juan Manuel Santana.
This required to change school bus routes, so that children in the municipality of Frontera Valverde studying in his school reach across the top of the island.
The half a hundred people on Tuesday were evicted from their homes in the town of Frontera spend another night outside their homes (most are staying with family and only a dozen remain in the dorm Valverde), but tomorrow review your situation and decide whether they can return.
This was noted by the President of the Cabildo, Alpidio Armas, who has stressed that the islanders will have to learn to live with the situation presented in El Hierro from mid-July, a period in which the island has been rocked by more than 8,000 low-intensity earthquakes of volcanic origin, most imperceptible.
"This is a topic that we will have to learn to live, if not stopped. We're going to have to integrate into our lives, peace and responsibility," added Armas.
The chairman of the council has insisted the message of tranquility that all authorities have been saying for days and stressed that the scientific reports indicate that the situation appears to have entered a stationary phase.
In the same vein, Santana pointed out that such events are cyclical seismic events caused by the pressure of magma in the subsurface, so that "fall within the normal." In fact, the volcanic risk in light of El Hierro is still located in yellow, in a situation of "pre-alert."
The Director General of Security of the Canarian Government has also explained that the latest information available indicates that the focus of the earthquake is shifting to the south of the island.
Update 29/09 – 17:44 UTC : NO new press reports from the authorities today. Less earthquakes than yesterday (20 above or equal to Magnitude 2 - midnight UTC until 17:23 UTC)). More powerful tremors though. 10 tremors above or equal to magnitude 3.0. The strongest one was 3.8.
Scientists are guessing that the chance on an eruption will be max. 10%. Main reason the continuous depth of the magma movements in between 10 and 15 km. The increasing magnitudes are not giving any clue on a near eruption as the magma would have to find its way to the surface. So far we do not see shallow earthquakes.
All scientists are looking with a magnifying glass to the events and are not alarmed yet.
As said before, the precautionary measures that the authorities have declared are for EARTHQUAKES and LANDSLIDES reasons, NOT for a near eruption.
We are also following the events with a magnifying glass, so please return regularly for eventual

Update 29/09 – 20:44 UTC : New press report from PEVOLCA (committee of authorities and scientists) has decided to :
- allow the return of residents of Los Corchos, El Lunchon and calle Carrera to their houses.
- The Los Roquillos tunnel remains closed until further notice
Reason : same level of volcanic earthquakes and the epicenter of the tremors is moving to the south into the ocean.

Kut translate laat niet alles duidelijk over komenquote:The Canary Islands government radio alert to all operators of the impending El Hierro volcanic eruption
The Canary Islands government radio alert to all operators of the impending El Hierro volcanic eruption on the island 12 kilometers
Scientists believe that in the next few hours can produce a 99% chance of eruption
Measurements and forecasts made by scientists on the island of El Hierro and the whole structure of IGN have pointed to the competent authorities within the Pevolca activated by the Canarian Government to the volcanic eruption is expected for several days can occur in next few hours at a point in the sea to twelve miles off the coast southwest of the island, which correspond to the town of Frontera.
The odds set by these scientists have risen to 99%, giving the reason Carracedo, which set the deadline for its experience and professional expertise long before any of that until now have come to the public.
In order not to alarm the population is deciding when to make public a statement giving an account of this incident, but was ordered by radio high alert all operators to be prepared, especially in the EMU and its device that includes a shelter for 2,000 people, if it is considered that the entire population evacuated.
At this time the technicians of the Canary Islands from the Cecoi El Hierro are already coordinating emergency resources and security and all air and sea operating when the eruption occurs.
3.0 beving klein uur terug nog... en als ik de link uit de OP bekijk rommelt het aan één stuk door daar
Eindelijk pikt ook andere media het op...
quote:Vulkaan op Canarisch eiland staat op uitbarsten
Het Spaanse Canarische eiland El Hierro kreeg sinds 19 juli al duizenden aardbevingen te verwerken, waardoor magma naar het aardoppervlak geduwd wordt. Er wordt dan ook gevreesd dat het tot een vulkaanuitbarsting komt. Lokale functionarissen deelden woensdag nog mee dat meer dan vijftig personen uit het noordelijke dorp Frontera werden geëvacueerd uit angst voor aardverschuivingen.
Het leeuwendeel van de aardbevingen waren te zwak om door de eilandbewoners opgemerkt te worden, maar ze namen wel steeds toe in frequentie en intensiteit. Gisteren werden meer dan 100 trillingen opgetekend, waarvan de sterkste 3,8 op de magnitudeschaal haalde. Vandaag volgden opnieuw tientallen bevingen, waardoor de belangrijkste wegentunnel van het eiland werd afgesloten en honderden schoolkinderen thuis moesten blijven.
Op het eiland bevindt zich ook één grote vulkaan en ongeveer 250 kraters. De autoriteiten zien echter geen dreigende vulkaanuitbarsting, dat gebeurde op El Hierro voor het laatst in 1793. Indien het toch zover zou komen, is het niet nodig om alle tienduizend inwoners te evacueren, zei veiligheidschef Juan Manuel Santana aan de krant El Pais.
Veiligheidsverantwoordelijken zouden aan verschillende evacuatiescenario's aan het werken zijn. Ook worden overal op het eiland vergaderingen gehouden om de inwoners te informeren wat er moet gebeuren in geval van een uitbarsting.
Is er nou wel of geen risico tot uitbarsting? Ik lees zoveel tegenstrijdige dingen :S. Dan worden mensen geevacueerd, en even later worden ze weer terug gestuurd en is er geen beving meer waargenomen :S.
Check de link uit de OP... geen bevingen? Volgens mij alleen vanochtend al dertig ofzo:Dquote:

Jon Seach heeft inmiddels ook een stuk over el Hierro 
quote:Hierro Volcano - John Seach
El Hierro, Canary Islands, Spain
27.73 N, 18.03 W
summit elevation 1500 m
shield volcano
El Hierro volcano is the westernmost, youngest and smallest of the Canary Islands. In the 2nd century A.D., Ptolemy considered it the western-most position of the world.
El Hierro Island covers an area of 278 sq km, and contains three well-defined ridges, arranged at approximately 120 degrees. According to the hotspot model of volcano formation, the current location of the Canary islands hotspot is under Hierro Island.
El Hierro volcano is still in its juvenile stage of shield growth, and has been modified by gravitational spreading which caused gigantic landslides. There are three volcanic structures on El Hierro Island - elongated topographic ridge (the Southern Ridge) and two semi-circular volcanic cones (Tinor volcano, El Golfo volcano).
Tinor Landslide was the earliest and directed to the northwest of Hierro Island.
El Julan produced a 15 km wide embayment in the southwest of the island. The landslide was approximately 60–120 cubic km in volume, and covered 1600 sq km of ocean floor.
Las Playas Landslide directed SE and had a volume of 25-35 cubic km.
El Golfo, Debris Avalanche
El Golfo is a major debris avalanche on the northern flank of Hierro Island, dated about 13,000 years ago. It has a width of 15 km and a scarp height of 1000 m. The landslide deposited 150-180 cubic km of debris on the seafloor down to a depth of 3000 m.
2011 Unrest
An earthquake swarm occurred at El Hierro volcano in July 2011 with 720 earthquakes measured in a week. The earthquakes were measured between magnitude 1-3, and most were at a depth of 5-15 km. The swarm occurred at El Golfo in the northwest of the island at the location of a landslide that created a 100 metre high tsunami about 50,000 years ago. The earthquakes were continuing at the end of September and some evacuations were ordered for people living near the volcano.
