The Scientific Committee for the Evaluation and Monitoring of Volcanic Phenomena (CCES) has confirmed "anomalous" volcanic activity at Mount Teide, though experts emphasise that there are no signs of an imminent eruption. However, they note a heightened likelihood of volcanic activity in the medium to long term.
This update was shared by the Canary Islands government following an extraordinary committee meeting on Thursday.
Increased Pressure in Teide’s Hydrothermal System
Key findings from ongoing investigations and monitoring reveal significant changes in seismic, geodetic, and geochemical indicators since 2016, with activity intensifying since 2022.
These changes, attributed to rising pressure in the hydrothermal system beneath Tenerife, highlight the need for increased vigilance. Notably, altered gas emissions from Teide correlate with a pattern of increased seismic activity, particularly around Las Cañadas, Cumbres de Adeje, and Vilaflor. In Vilaflor alone, 14 earthquakes were recorded within 24 hours earlier this week.
Reassurance from Authorities
Manuel Miranda, the Canary Islands Councillor for Territorial Policy, sought to reassure residents, urging "calm and prudence" amid public concerns following recent seismic swarms.
He highlighted the efforts of the Canary Islands Volcanology Institute (Involcan), the Spanish National Research Council (CSIC), and the Directorate General of Emergencies, who are collaborating on projects to update risk maps and improve monitoring systems.
Transparency remains a priority, with the government pledging to make the scientific committee's findings publicly accessible through the Territorial Policy Department's website.
Recent Seismic Activity
Recent months have seen notable seismic swarms, including a swarm in June and July 2023 at depths exceeding 30 kilometres near Santiago del Teide. Another occurred later in 2023 at depths of 17 to 23 kilometres beneath Las Cañadas. Smaller seismic clusters have also been identified under Izaña and the peaks of Arico.
Potential Risks
The Canary Islands government continues to operate under its Special Civil Protection and Emergency Plan for Volcanic Risk (PEVOLCA), ensuring preparedness for any escalation in volcanic activity. While there is no immediate eruption risk, the identified anomalies point to a dynamic subsurface environment that warrants continued scientific scrutiny.
The public is encouraged to remain informed through official updates and to follow any guidance provided by emergency authorities, particularly in areas experiencing increased seismicity.
