Protective measures removed for the population of El Hierro

Protective measures removed for the population of El Hierro

The normality returns, for the moment, to El Hierro. The stability of the seismic-volcanic phenomenon has allowed the Emergency Plan Volcanic Islands (Pevolca) rule that it can suspend the measures taken so far. These affected a dozen people from the north, who had evacuated since early November, and the reopening of roads were closed, and the possibility of using the tunnels Roquille 24 hours a day.

The mayor of La Frontera, David Cabrera, has man been satisfied by the return to normalcy in the area.

The only measures which remains is the closure of the bays of Puerto Naos TacorĂ³n and as long as the underwater eruption continues can not be ruled out that emissions of gases that accumulate there.

The reason for the decision is that the southern eruptive process runs its course without more novelty other than emissions variables to the sea. To the north are not expected earthquakes of a magnitude greater than 4.5, so that the risk of landslides has increased in an area where, on the other hand, there are continuous phenomena of this kind by the rains, according to neighbors.

All other indicators remain within expectations. CO2 levels rise, but that is normal because there are still emissions from magma, even underwater. The tremor is constant, and ground deformation increases somewhat in the north. However, there is no prospect of opening a new volcanic vent in the area.

The ship measures Ramon Margalef indicate that the cone in front of La Restinga loses height, confirming that there have been landslides.
