The new station, a Raspberry Shake type, integrates into the seismograph network deployed across several municipalities on the island. Its primary objective is to collect exhaustive data to detect any signs of magmatic movement and increase the capacity for anticipation of potential volcanic eruptions.
Fasnia, with a significant volcanic history linked to the eruptions of Siete Fuentes, Fasnia, and Arafo in the early 18th century, recognizes the importance of having monitoring instruments within its territory. Detecting low-magnitude seismicity is crucial, as it often serves as an early indicator of subsurface changes.
Raspberry Shake seismographs are compact, low-cost devices combining a microcomputer with a geophone and amplifier. They record ground vibrations and transmit data via the internet, facilitating the localization of small earthquakes and improving the instrumental network's coverage, particularly in southeastern Tenerife.
Information gathered by the Fasnia station, along with data from other island stations, is available on the Raspberry Shake StationView platform, allowing real-time data, location, and nearby station status to be viewed. This data is open to the scientific community, educational institutions, and the general public.
The mayor of Fasnia emphasized that collaboration between administrations and data access enhances security against potential volcanic risks. This initiative is part of the reinforcement of volcanic surveillance networks and complements the outreach and emergency preparedness activities conducted in the municipality.
INVOLCAN reminds that this network complements official surveillance, and alerts regarding the alert level are issued by competent bodies such as the National Geographic Institute and the Scientific Committee of PEVOLCA. The public must always follow information from civil protection authorities.
