Authorities in Tenerife have initiated large-scale emergency preparedness measures following reports of increased seismic activity and magma accumulation beneath the Teide volcano. In September 2026, Spanish officials conducted the ‘EU-Modex Tenerife 2026’ drill in Garachico, involving approximately 1,000 participants to test communication systems and evacuation procedures.

Scientific monitoring has identified four anomalies under the volcano, suggesting the presence of partially melted material. This follows a period of heightened seismic activity in the Canary Islands; in August 2026, 135 earthquakes were recorded in the region, including a magnitude 3.6 quake, while Tenerife itself experienced 38 smaller tremors.
