The mean amplitude of the volcanic tremor has increased but little change in the behaviour of earthquakes.

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

Lava spreads and prompts confinements which are later lifed as risk reduces.

Since the 11th of October, 64 earthquakes have been located in the area; 6 of these earthquakes have been felt by the population. The maximum intensity in the epicentral zone was IV due to an earthquake that occurred at 07:16 UTC on the 12th, with a magnitude of 3.9 (mbLg) at a depth of 12 km. However, the largest earthquake experienced in the last 24 hours was a 4.1 magnitude (mbLg). Of the earthquakes located in the last 24 hours, 4 are found at depths greater than 30 km, and the rest of the hypocenters are located at a shallower depth, around 12 km. The mean amplitude of volcanic tremor has increased with respect to the mean value. The height of the eruptive column measured at 6:30 UTC is 3,500 m (IGN, 2021). The northern most lava flow threatens areas of La Laguna (GVP, 2021).

This video taken on the 12th of October shows a later lava flow overriding a previously emplaced lava flow and subsequently setting vegetation on fire. Sourced from IGME (2021).
