La Palma eruption update 6th october 2021: The eruption remains relatively stable

Daily summary

A relatively stable period in the eruption continues, both in respect to the paths taken by the lava flows and the surface eruptive activity. The lava flows continue to feed the lava delta via lava tubes, and the eruption continues to show a strombolian behaviour from multiple active vents in the main cone that vary in intensity, as well as more effusive activity from two vents on the flanks of the main cone. There was a small breakout lava flow flowing towards the north of Todoque mountain, although for now these flows have become inactive. For the first time since the eruption began, damage statistics for agriculture have been published; 93.4 hectares have been affected by the lava flows so far, including 35.6 hectares of bananas and 32.9 hectares of vineyards.

The meteorological conditions are expected to become more unfavourable with respect to air quality in the coming days, as the height of the thermal inversion is expected to decrease. Regarding deformation, relative stability is seen throughout the network. Earthquake activity continues to be concentrated at 10-15 km depth in the area of the precursory swarms, although at lower levels than observed on the 4th October. 57 earthquakes were recorded, peaking at 3.9 mbLg. The ash plume height was 3000 m, although no data was published regarding the SO2 emissions in the plume, although given the stability in activity it is expected to be similar to the values registered on the 5th October.

Notes: The size of the points represents the size of the earthquake, and the colour represents the depth. The map will also only show a certain number of points at once. For ease of use, we recommend you uncheck all dates and the satellite basemap from the legend in the top right, and inspect the earthquakes one day at a time.
