Suwanose-jima (Ryukyu Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 6000 ft (1800 m) altitude or flight level 060 and is moving at 10 kts in S direction.
The full report is as follows: EXPLODED AT 20230215/1440Z FL060 STNR OBS VA DTG:15/1500Z to 6000 ft (1800 m)

Karangetang (Siau Island, Sangihe Islands, Indonesia): (15 Feb) The extrusive/effusive eruption at the volcano continues.
Available source images, from either the Sentinel-2 satellite or the MAGMA Indonesia observatory, suggest sustaining arriving of fresh magma into the lava dome in the inner summit crater from where overflows the rim and oozes out to several directions in the form of incandescent rockfall avalanches.

In addition, a magnificent lenticular cloud was being illuminated above the crater resulting from the glowing crater and avalanches. Lenticular clouds form when moist, stable air flows over a larger swirls, usually formed by mountains, a series of large-scale standing waves form on the leeward side of the mountain. If the temperature at the crest of the wave drops below the dew point, moisture in the air may condense to form these clouds.
The Volcanic Alert Level remains at Level 3 (Siaga).
