The National Center for Volcanology (Cenvul), a new service set up by the Geophysical Institute of Peru (IGP) for the benefit of the country, which started its activities on March 1 of this year in the region of Arequipa, will be officially presented on July 15 at a ceremonial ceremony attended by the authorities of the Ministry of Environment and representatives of institutions related to disaster risk management in the country.

The information generated by Cenvul allows reports and warnings to be produced on volcanic processes that can cause eruptions, which could affect more than 2 million people living near volcanic structures. Therefore, this information is essential for the authorities to make timely decisions to safeguard this population in the south of the country.

 

This was demonstrated with the publication of reports and alerts 10 days in advance before the partial eruption of the Ubinas volcano, which took place on June 24th. Thanks to the information provided on time, the authorities adopted immediate preventive measures, such as the Orange alert by the regional government of Moquegua.4

Hernando Tavera, IGP Executive Chairman, explained that Cenvul's objective is to provide official information on the evolution of volcanic activity in Peru, based on the technical-scientific analysis of the data collected in Peru. real time from 75 state-of-the-art instruments.

Reports and alerts issued, freely accessible, are handed over to the authorities so that the corresponding measures are taken to protect the population, he said.
