New vents and a landslide on the main cone

New vents and a landslide on the main cone

Red traffic light

Vertical uplift and subsidence near the eruptive centre

Renewed phreatomagmatic and strombolian activity

Since the last statement, a total of 91 earthquakes have been located in the area, 6 of them felt by the population. 73 of these earthquakes are located at depths 10-15 km and the rest at depths greater than 30 km. The maximum magnitude recorded is 3.6 (mbLg) corresponding to yesterday’s earthquake at 13:53 UTC, with a depth of 36 km. The amplitude of the tremor signal increased during the night. The island’s network of permanent GNSS stations shows a reversal of the elevation recorded between November 24 and 26 at station LP03, which is the closest to the eruptive centres. LP01, the station further from the eruptive centre, continues to register deflation. Using a calibrated image IGN estimated at 08:45 UTC, a column height of 1,600 masl and a scattering cloud in the southwesterly direction. The height of the cone is measured obtaining a value of 1,126 masl (IGN, 2021). Today new vents opened on the North East flank of the main cone around 0300 producing fast flowing, fluid lava flows that traveled North and North West through the Tacande area. Landslides were observed on the North West flank of the cone (GVP, 2021).

This video taken on the 28th of November shows RBG and thermal data of a lava front which inundates banana plantations, produced by a new emission centre that has opened in the North East sector of Tajogaite. The ash plume is produced by renewed strombolian and phreatomagmatic activity at the higher elevation vents deposits ash on the houses that have not been impacted by the lava flows.
