Overview

• IGN detected around 700 microtremors beneath Teide at depths near 10 km southwest of Pico Viejo on August 7
• All events registered were of magnitude under 1 and went undetected by residents, with the lowest-energy quakes recorded solely by automatic systems
• This marks the sixth seismic swarm in the Cañadas del Teide area since 2016, reflecting the volcano’s inherent background activity
• Involcán’s network distinguished a volcano-tectonic swarm of 71 events (max mag 1.5) and a hybrid swarm of about 637 events occurring between 7 km and 14 km depth
• Recent studies have identified shallow magmatic reservoirs under Las Cañadas caldera, but current tremor patterns show no signs of magma intrusion
