La Palma eruption update 5th october 2021: 420 hectares now covered by lava flows

Daily summary

The two effusive vents that opened a few hundred metres NW of the main cone on the 1st October no longer show any activity, according to PEVOLCA. However, the Strombolian vents in the main cone and those on the flanks of the main cone are still active. Activity in the fumarole field on the SE flank has decreased, although gas emission and high soil temperatures have been observed 100 m NW of the newly inactive vents. It is noted that no eruptive parameters indicate the eruption could be near its end. The active lava flows predominantly travel from the main cone to the lava delta, which is now 36 hectares in size, via lava tubes. The lava flows travelling on top of the existing lava flows also remain well contained and as such there is currently limited widening of the area affected by the flows. Latest assessments indicate 420.12 hectares are covered by lava flows, with the lava flow field being a maximum of 1,250 m wide. Assessments of the marine environment have indicated that physio-chemical parameters of the sea water have only been affected between 0-250 m depth, within 500 m of the front of the lava delta.

The meteorological conditions remain favourable in terms of air quality, and this is reflected in SO2 and PM10 concentrations. Low concentrations of both SO2 and PM10 particles and PM10 have been observed across the network. Regarding deformation, the distal stations still show a slight downward trend, although vertical stability is now seen in the proximal stations. Earthquake activity continues to be concentrated near where the precursory seismic swarm began on the 11th September. 48 earthquakes were recorded, peaking at 3.9 mbLg. The ash plume height was 4000 m, and the SO2 emissions were decreased, at 5,849 tons per day.

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.
