The Consell and the UA identify the red zones of earthquakes in the province: the Vega Baja and the border with Valencia


Delgado did emphasize that «what has to be taken into account is that, when building, the current technical standard must be respected to the maximum and rigorously applied. The map that we have made reflects the areas where more or less high ground accelerations can occur, according to historical data. The earthquake resistant standard sets the criteria with quality. There we must be rigorous as citizens, “said Delgado.

The map is a good complement for technicians when planning constructions. Delgado stressed that it is not above the norm, but it can help. «The map is useful in many ways. To design emergency plans and anti-seismic design. Everything that is to implement measures to improve the response to earthquakes is important, “said Delgado.

For his part, the Minister of Territorial Policy, Public Works and Mobility, Arcadi Spain, classified the seismic maps of the Valencian Community, prepared by the Institut Cartogràfic Valencià (ICV) with the collaboration of the University of Alicante, as “A fundamental element of public management” for both territorial and emergency planning. In the presentation of the maps of seismic danger and of active faults and seismicity, as a result of the agreement signed between the ICV and the University of Alicante, the minister stressed that “knowing our territory is essential to guarantee a quality of life to our citizens and citizens ».

For Arcadi Spain, «this map allows us to better design the instruments of territorial planning, to identify the places in the Valencian Community where we should have more careful for that seismic risk that is there, to be aware that we live in a territory where this risk exists ». In addition, he stressed the importance of this cartography to plan the emergency services in a correct and effective way. “In these two essential areas, emergency and planning, collaboration between the Generalitat and the University of Alicante is essential to have this map of seismic risks and to be able to all work with more care and precision,” added Arcadi Spain.

The maps have been incorporated into the autonomous collection of thematic maps CV350 of the ICV. On the one hand, the seismic hazard map of the Valencian Community has been made for a return period of 475 years with seismic data obtained from the database of seismogenic zones of the Iberian Peninsula and territories of influence to calculate the hazard. seismic in Spain published by the Geological and Mining Institute of Spain.

On the other, the map of seismicity and active faults in the Valencian Community has been designed, with thematic data obtained from the catalog of earthquakes prepared and maintained by the National Geographic Institute and from the QAFI database (Quaternary Active Faults Database of Iberia) .

This series can be downloaded, in pdf format, from the Valencian Spatial Data Infrastructure website (IDEV, ICV (gva.es)) and from the ICV website (http://www.icv.gva.es/va/col-leccio-autonomica). At the beginning of the year, a collaboration agreement was signed between the ICV and the University of Alicante for the continuity, maintenance and densification, if applicable, of the seismic network that this university manages, and to extend its seismicity control activity throughout the territory of the Community.

Torrevieja currently has the record for destruction by an earthquake. It was 6.15pm on March 21, 1829, when the earth shook with an intensity of 6.6 degrees on the Richter scale at the Vega Baja, the region that suffered its great and devastating earthquake. It was Saturday night, and most of the neighbors were caught at home. In houses of various heights, without foundations, with little resistant wooden beams and in narrow streets, so that they were falling and dragging those of the neighbors with them. There was no stone on stone in Torrevieja, Guardamar had to be redesigned and Almoradí suffered even more.

In the Vega Baja region, 2,965 houses were “devastated”, another 2,396 “ravines”, following the terminology of the time. The damage count was detailed by churches (30 neither more nor less in “Orihuela y su Partido”, two in Almoradí, another two in Formentera … 47 in total), by bridges (four) or by oil and flour mills (86 and ten respectively). But the hardest count was that of the dead and wounded: 386 and 375 in the region, 192 and 150 only in Almoradí, where the greatest damage was recorded.
