There is sound in this video.
As first noticed by WUWT commenter Crosspatch last night, from seismic data, it appears Mt. Redoubt has erupted:
Crossptach at 9:41pm
Looking at this Redoubt webicorder it looks like an eruption of some sort might have started at around 2045UTC. It’s dark there now, so we won’t know until morning.

Because the eruptions happened at night, so far we don’t have any current photography. Hopefully soon. The radar image above shows the plume clearly though. Here is a 40 frame loop showing the eruptions. (h/t Tom Woods) – Anthony
Noon Update: The most recent volcanic ash advisory from Anchorage VAAC, issued at 17:25 GMT (09:25 local time) gives the plume altitude as FL600, which is 60000 feet ot 18 kilometers (h/t to The Volcansim Blog )
FoxNews: Alaska’s Mt. Redoubt volcano erupted late [Sunday and early Monday] in “four large explosions,” sending an ash plume an estimated 9 miles into the air, the Alaska Volcano Observatory reported.
“The ash cloud went to 50,000 feet, and it’s currently drifting toward the north, northeast,” said Janet Schaefer, a geologist with the Alaska Volcano Observatory.
Geologists at the observatory say the volcano, located 100 miles southwest of Anchorage, erupted four times, from 10:30 p.m. to 1:40 a.m. local time.
“This is a fairly large eruption, close to the larger cities in Alaska,” Geophysicist John Power said.
The current wind patterns are taking the ash cloud away from Anchorage and instead heading toward Willow and Talkneetna, two communities near Mount McKinley, North America’s largest mountain in Denali National Park.
