Look at the water that is now flowing in the Tuttle Valley (foreground of the webcam shot). It was a dry river bed earlier today - the eruption must have melted some glacier ice.
Picture that mountain about a third to 40% bigger with a top crest. That's what existed before the 1980 erruption. That blew the top part clear off.

Cams 1, 2, and 3 all work. Cam4 must not be active yet. Cam 1 and 3 are the best.
