Earthquake magnitudes, intensity, and quantity increase and deflation of the eruptive centre is observed.

Since yesterday 41 earthquakes have been located in the area, 6 of which were felt by the population with a maximum intensity of III. Most of the epicentres remain 10-15 km deep, but 4 were recorded with a depth greater than 35km. No pulses of volcanic tremor were recorded in the previous 24 hours. The column height, measured at 6:30 UTC, was 3,000 m, showing a slight descent of the eruptive cloud. The island’s network of permanent GNSS stations shows slight deflation in the vertical component of the stations near the eruptive centres (IGN, 2021). A breakout lava flow from the western end of the main flow destroyed crops and buildings between Los Guirres and El Charcó (GVP, 2021).
