The Pevolca allow the return home of all evacuees


The Pevolca allow the return home of all evacuees

The direction of the Civil Protection Plan for Volcanic Risk (PEVOLCA) today authorized the return home of all the neighbors who remained evacuated in the area of Las Puntas and the Pozo de Las Calcosas and the opening of the Eco-museum and El Lagartario and the reopening of the roads were closed at night, said today in a statement PEVOLCA.

The statement added that the roads that were closed were the HI-5, where the tunnels Roquille, HI-500 and HI-50.

However, the statement says, we must stress that it is maintained a red light, Level 1, for La Restinga, in the municipality of El Pinar, and yellow for the rest of the island.

The only Civil Protection extraordinary measures that are currently maintained are the ban on access to the beaches of Puerto Naos and Tacorón and maritime exclusion zone.


 The tunnel Regarding Roquille, the letter stated that the Department of Infrastructure of Roads will create a work area where there were defects in the shotcrete, so , together with the City Council of El Hierro, which will to clarify when and how to open the lanes, meaning Valverde Frontera, which was closed by the studies that were performed.
These decisions are made due to the reduced chance to occur high seismicity of magnitude exceeding 4.5 on the Richter scale, the maximum level established for the IGME that could produce landslides on the slopes of the tunnel.

In addition, the earthquakes that are occurring are occurring at a depth of more than ten miles.

On the other hand, has proceeded to place three accelerometers in the escarpment of the slope adjacent at Frontera tunnel, which allows greater control of potential landslides.


 As preventive measures, the following will remain in El Hierro equipping the Red Cross and the EMU, as well as network communications, transport and port stations Advanced Command (PMA).

Regarding the Volcanic and Earthquake crisis PEVOLCA Scientific Committee reported that we are in a more relaxed state because in the past fortnight there has been no significant seismic activity, the magnitudes of the movements have been below 3.7, the horizontal deformation do not have a vertical pattern and remarkably show a downward movement with the exception of El Golfo.

In the latter case, the west, Sabina and Pozo de Salud are aimed at stability.

As for the eruptive process of La Restinga, the Scientific Committee said that is ongoing, as evidenced by the finds in the tremor amplitude confirming that the volcano is still emitting material and depending on what it is colored differently.

Since the first bathymetry by the scientific team Ramón Margalef ship has seen a decrease in the height of the volcano, which means that sectoral frequent landslides are producing typical underwater eruptions.


 Although the emission level has registered an increase it must still be observed, according to the Institute volcanological de Canarias (Involcan), this is understandable because magma is still moving.

Finally, the Scientific Committee said that the scenario of a possible eruption in the north is still open but said that the situation is not clear, nor is it imminent at the time.
