A new explosive eruption marked the Bogoslof on 24 January at 4:53 am AKST / 13:53 UTC, spotted by the lightning detection system and the seismic network; the cloud, rich in ice, but presumably containing ashes, rose to 7,600 meters, moving eastward.
After a brief transition to red, the aviation alert is for the moment orange

Another volcano monitored by the AVO, the Takawangha stratovolcano, passed in yellow aviation alert / volcanic alert Advisory yesterday, following an energetic seismic swarm, located 6-7 km east of the volcano. No volcanic activity was detected by the satellites.
Located on Tanaga Island, in a saddle between the Tanaga volcano and other ancient volcanoes, the Takawangha has not experienced any historical eruptions.

No evolution at Mount Etna, where after the explosions marking the saddle between the south-east craters that blackened the snow covering the volcano, we see on 25 January at dawn only a degassing, the effects of which are reinforced by high humidity and low wind.
