Early warning systems



Official Bulletin of Canary Islands num. 154

Canarias is the only Autonomous Community that registers an important volcanic activity within the Spanish State, having suffered in the last sixty years several volcanic crises of relevance. The characteristics of a volcanic emergency, its probability of occurrence, as well as the important consequences for the population, goods or the environment, in a limited and widely populated territory make it necessary to develop a Special Emergency Plan for Civil Protection that guarantee a rapid, effective, efficient and coordinated response, aimed at minimizing possible damages and allowing the reestablishment of basic services for the population in the shortest time possible.

PEVOLCA aims to ensure a coordinated, agile, effective and efficient response of all public administrations to cope with seismovolcanic crises, which can lead to both subaerial and submarine eruptions, and emergencies arising from them and that originate in the territory of the Autonomous Community of the Canary Islands, as well as ensuring compliance with the prevention measures contemplated in current regulations.

The activation and deactivation of the Plan is declared by the director of PEVOLCA, based on the critical point at which preventive measures must be taken to avoid at all costs the risk to people’s lives. Taking into account that the volcanic risk comprises a series of actions to be developed sequentially, a system of alert to the population based on the selection of four colors has been established worldwide. In this way the population can adopt certain behaviors based on an easy to understand symbol is the so-called volcanic traffic light. Its objective is for citizens to always identify the same language on the part of public authorities regardless of the nature of the risk.
