Since last Sunday in the area have been over 750 earthquakes
The pressure of the magma detected in El Hierro has caused in the past four days on the island deformation of four to five inches vertically and three to four horizontal, as reported by the Security Directorate of the Canary Islands.
The energy released has reached 420,000 million joules, a fact which, together with the ground deformation evidence magmatic process acceleration on the Canary Island, where there is an inflation process is centered in the area which earthquakes occur.
The General Directorate of Security, who coordinates the Civil Protection Plan Risk Volcanic Islands, said that since the beginning were found in magmatic process, last Sunday, have occurred in El Hierro over 750 earthquakes.
In the Sea of Calm
The earthquake with greater magnitude of 4.0 degrees on the Richter scale, occurred on Wednesday at 18.55 hours in the Sea of Calm, 2 km from the coast and 20 kilometers deep.
The seismic activity began in the Sea of the Gulf (north of El Hierro) and then move to the center of the island, coinciding with the point of intersection of the ridges, to subsequently migrate to the west.
From noon on June 25 the seismicity is concentrated in an area that includes the west and the dorsal side of the Julan, and from 1200 hours on June 27 the focus of the earthquake begins to migrate towards the Sea of Calm .
