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.

The main flow had passed village of Todoque and destroyed the church of San Pio X, and was located only about 1.6 km from the sea. As a precaution to an expected sea entry in the near future, authorities ordered curfew for the localities of San Borondón, Marina Alta, Marina Baja and La Condesa, where people were not allowed to leave their homes and should keep windows and doors closed.
SO far, lava flows have destroyed more than 450 buildings and covered an area of 212.1 hectares.

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

…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.

During the past 24 hours, there were 17 quakes of magnitudes from 2-3, the largest a 3.2 quake 11 km south of Los Llanos de Aridane at 8.05 a.m. this morning.
Last night, activity actually picked up and we observed very strong and tall lava fountains until about 1 a.m., although we had the impression that the ratio of lava and gas was smaller in the fountains than earlier on. After this, during the early morning hours, fountains decreased and abruptly stopped.

Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20210927/1839Z FL070 EXTD W OBS VA DTG:27/1840Z

Pagan (Mariana Islands): The Northern Mariana Islands Volcano Observatory published that no unrest or activity has been observed at the volcano in satellite data since September 6.
