La Palma (Canary Islands (Spain)): Volcanic tremor remains at low values, with some short pulses of intensification, similar as yesterday. No significant change in ground deformation was detected and earthquakes have also been similar as yesterday.
IGN reported a total of 98 earthquakes during its latest 24-hour reporting interval, with 6 of them felt by the population. The strongest quake in the past 24 hours was a magnitude 4.8 event at 1.03 a.m. local time.

...23 Nov:
Another branch of the active lava flow made it to the ocean today, traveling south of the one that reached it yesterday and creating yet another sea entry.
On its path down the sea cliff, it has been destabilizing rocks from the cliff wall, which have been falling down in rockfalls that generate thick dust clouds in addition to the steam from the lava entering the ocean.


Suwanose-jima (Ryukyu Islands): Volcanic Ash Advisory Center Tokyo (VAAC) issued the following report: EXPLODED AT 20211123/1407Z FL040 EXTD SE OBS VA DTG:23/1400Z

Taal (Luzon, Philippines): (23 Nov) The observatory PHIVOLCS recorded three short-lived phreatomagmatic bursts at the volcano at 08:11, 20:17 and 20:34 local time today lasting about 5 minutes.
The explosive activity was accompanied by emissions of steam-laden plumes which reached approx. 1,5 km above the fumarolic vents drifting southwest. Presence of water is likely causing significant explosive interaction (phreatomagmatic activity) of water and magma.

Semeru (East Java, Indonesia): (22 Nov) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 14000 ft (4300 m) altitude or flight level 140 and is moving at 10 kts in SW direction.
The full report is as follows: VA TO FL140 AT 22/2233Z OBS VA DTG:22/2240Z to 14000 ft (4300 m)

White Island (New Zealand): (23 Nov) The GeoNet volcano observatory did their weekly visual, gas and temperature measurement flights last week.
Gas measurements revealed a decreasing trend of volcanic gases since 2 November. Sulfur dioxide (SO2) emissions decreased from 681 to 484 tonnes/day. Carbon dioxide (CO2) emissions decreased from 2712 to 1416 tonnes/day as well as hydrogen sulfide (H2S) emissions from 38 to 19 tonnes/day.
