La Palma eruption update 14th december 2021: No tremor or surface activity seen for more than 24 hours

Daily summary

Since the cessation of volcanic tremor on the evening on the 13th, it has remained at background levels now for more than 24 hours. No surface activity is seen from the main cone, and the lava flows on the surface are largely inactive. PEVOLCA say this may represent a sign of ‘exhaustion’ of the eruptive process but refuse to rule out a restarting of activity. The number of earthquakes increased yesterday to 91 events, peaking at M3.2. However, some of this increase is due to the fact that there is no tremor, as 56 lower magnitude events (<M2.0) were located which would not have been locatable due to the noise from the tremor in normal eruptive conditions, according to IGN. Seismicity again remains concentrated at intermediate (<20 km) depths. Deformation remains stable throughout the network, as seen for the past week or so.

SO2 emissions from the volcano still remained high however on the 13th when the latest data was collected, although yesterday air quality with respect to SO2 concentrations was good or reasonably good, showing a marked improvement relative to previous days. PM10 levels were also good or reasonably good in all stations aside from Los Llanos de Aridane, where unfavourable levels were recorded at times.

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.
