La Palma eruption – 24th December 2021

Daily summary

Volcanic tremor continues at background levels, with no eruptive activity seen, although a reactivation cannot be ruled out. If the current levels are maintained, the authorities will be able to call an end to the eruptive process on the 25th December. PEVOLCA reminds the population however that end of the eruption does not mean the end of the dangers from the volcano, and that declaring the end of this eruption is not the same as declaring the end of the magmatic reactivation in Cumbre Vieja.

The deformation recorded at the LP03 station in Jedey that began on December 19th, the closest GPS station to the eruption, has now fully reversed. Across the rest of the network, no other trends are seen across the deformation network. PEVOLCA again reminds that in the El Hierro eruption, residual seismicity and deformation also occurred as the subsurface re-adjusted. 16 earthquakes were recorded, peaking at M3.0 with 10 <M2.0, largely at intermediate (<20 km) depths.

The level of SO2 emissions from the plume were maintained from the previous days, registering a low (50-500 tonnes per day) value. PEVOLCA continues to explain these emissions are due to the solidification of superficial magma in the conduits, rather than magma ascent. Evacuated people looking to enter homes must always be accompanied and permanent ventilate the homes, waiting 15 minutes before entering and not entering underground areas. Air quality remains good in all stations with respect to SO2 concentrations, and between good to reasonably good in all stations with respect to PM10 concentrations.

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.
