The renewed seismic activity process on the island of El Hierro since the 24th of June (2012) has now deformed the island by up to 6 centimetres horizontally and up to 7.5 centimetres vertically, according to data transferred by the IGN to the direction of Civil Protection Plan Volcanic Risk (Pevolca). As reported yesterday by the Canarian government in a statement, the magmatic process started last June 24th on the island of El Hierro continues and is behaving similarly to the last two days, both in seismicity and deformation to the island.
Data from IGN shows that, in the last 24 hours, the seismicity is located in a large area, with more ‘scatter’ than the previous days with numerous epicenters located in the sea. The area is to the west of the island, including the west part of El Julan and the Mar de Las Calmas which has experienced over 1,250 earthquakes, 165 of them above a magnitude of 2.7 degrees Richter. Yesterday there was a 4.0 degree earthquake. The depth of the earthquakes located in this area remains at around 20 kilometres.
IGN’s GPS network data records that the deformation continues to grow at a rate similar to that of the previous two days, both in the horizontal components and in the vertical, marking an apparent centre of pressure in the area of Mar de Las Calmas.
