While lava fountain and lava lake volcanoes have been getting lots of press recently (La Palma's Cumbre volcano and Kilauea, of course), Alaska's Great Sitkin (in the Aleutian Islands) has been puffing and bursting for quite awhile. Winter is coming, so the Alaska Volcano Observatory had a couple of these pictures from the summer, when it was visible.
The picture above was taken in May.
From August, showing vapor and gas emanating from the lava dome.
Satellite view from September, showing that the lava dome is still hot and still growing. The thing about lava domes is, they can suddenly collapse and then there's a big giant ash cloud filling the sky.
So we should keep watching.
