La Palma (Canary Islands (Spain)): Activity is picking up again. The volcano has been producing intermittent explosions with ash emissions from the new cone, at intervals of roughly every 10 minutes.
...27 Sep:
According to the national TV station RTVE, eruptive resumed later this morning with emissions of steam and ash, although we cannot confirm this. Live cameras show little activity so far and tremor remains very low at the time of this update. A friend near the eruptive site this morning could not see any activity at the vents.
Yesterday, the lava had formed a new, narrower lobe emerging from the broad main front (coming from the main source, corresponding to the original flows), that had advanced at fast pace of about 100 m per hour eastwards. At the same time, the lava flow from the secondary fissure vent at the NW base of the cone continued to form its own flow, which had been advancing along the northern margin of the main flow at approx. 30 meters per hour.

According to CAPELLA and Landsat-8 infrared detection system, two lava flows were revealed and detected in satellite images from 26 September.

A drone footage offers mesmerizing views of the current eruption site associated with the lava flows and fountains.
...27 Sep:
The eruption suddenly paused this morning: surface activity at the vents and volcanic tremor, a measurement of magma movement towards the surface, ceased.
Whether this indicates the end or just a pause in the eruption is too early to determine, but at this stage, it is better to asume that it is only a pause: Earthquakes have picked up again a bit, which suggests that magma pressure has increased underground and magma might be trying to find new pathways. This could lead up to a resumption of activity, either from new vents or by re-using the existing one.
