La Palma volcano update: Activity continues to slow down

The activity at the vents continues to decrease gradually, at least visually and audibly. Residents reported less explosions and less intense degassing noises. Explosions at the vent are intermittent and no longer as vigorous as before although ash emissions seemed to have picked up in the morning again.

On the webcam, it can be seen that lava emission continues, but also seems less vigorous. Some of it forms active lava flows on the lower flanks of the cone, overlapping older flows.

Volcanic tremor has remained at similar levels as yesterday, but continued to decrease overall. Hopes are emerging that the eruption might be approaching an end although this is still too early to be certain of.

A pair of two quakes with magnitudes 4.5 and 4.6 occurred last afternoon at 5.07 p.m. at approx. 38 depth within 10 seconds from each other, but so far, there seems not to be any significant change with other parameters (e.g. eruption intensity) that clearly correlates.
It is not known what the exact significance of these and other quakes is at the moment. Whether it is caused by an injection of new magma at depth, or gravitational adjustments perhaps caused by the depletion of magma from there or something else, is speculation. It might become clearer in the future (likely some time after the eruption ends), when the data currently collected by scientists will be more complete and when models will be made that can match the various data with the observations. For now, one can just wait and see…
