La Palma volcano eruption 2021: 27 Sep - eruption pauses and restarts

Early on 27 Sep, activity at the vents suddenly ceased completely, at least visually. Sporadic mild ash emissions and explosions restarted to occur around lunch, and became more frequent in the afternoon.
By early evening, the pause of the eruption (which might have been caused by a new intrusion at depth, disturbing the existing pathways) ended, as shown in the following sequence of images:
