In our previous article Global Earthquake update Sept. 2, 2011 we told you that the number of daily earthquakes recorded on the smallest of the Canary Islands (Spain), El Hierro, has increased considerably.
The total number of tremors recorded during the past five weeks has now exceeded 4200, according to the Instituto Geografico Nacional (IGN). The majority of the earth tremors range between 1 and 3 magnitude. More than 431 earthquakes, including one measuring 3.5 magnitude on the Richter Scale.
Latest news: The government of the Canary Island decided to relocate the entire population of El Hierro due to an increase in seismic activity.
Statement of the government of the Canary Island on September 3, 2011
Translate from www.avcan.org Pevolca The Scientific Committee, met this morning at the request of the Ministry of Economy, Finance and Security of the Canary Islands Government, decided to relocate the population of El Hierro directly, the most important conclusions from information gathered by seismic and volcanic National Geographic Institute (IGN) and the Institute of the Canary Islands volcanological (non-tip) on the earthquakes recorded on the island since last July.
For this design a specific communication plan which will include, among others, technicians and scientists from this committee, coordinated by the City Council of El Hierro, the spokesperson continues to assume given the green light situation in pre-alert, of peace for the population.
The pre-alert state is triggered given the time duration of this series and seismic in order to increase coordination between the institutions involved and the level of information to citizens who are beginning to view with concern a situation that qualifies the Scientific Committee “normal” given the volcanic Canary Islands
The Scientific Committee comprises, in addition to the Canary Islands Government, the National Geographic Institute, the Higher Council for Scientific Research (CSIC) and the Meteorological Agency, and the invitation of the Director Plan, on this occasion, the City Council of The Iron, the Cabildo of Tenerife and the Canary Institute of volcanological

The vast majority of the tremors have been recorded in the northwest of the 278.5-square-kilometre island at El Golfo, the location of a massive landslide that created a 100-metre high tsunami almost 50,000 years ago. A giant piece of the island cracked off, crashed down into the ocean and scattered along the seabed. This landslide of more than 300km3 gave rise to the impressive amphitheatre of the El Golfo valley and at the same time caused a tsunami that most likely rose over 100 metres high and probably reached as far as the American coast. Geologists hypothesised that a during a future eruption a similar landslide could potentially generate a “megatsunami” some 2000-3000 ft (650–900 m) high in the region of the islands. The huge wave would radiate out across the Atlantic and inundate the eastern seaboard of North America including the American, Caribbean and northern coasts of South America a mere six to eight hours later.”
