Rockfalls/glacial calving was seen and heard when we were at the Hut location about 6-8 times in the course of about 2 hours. If you are looking at the summit, this is to the left of the meltwater stream about halfway up the volcano. We could visually see the falls, and a few seconds later heard a thunderous noise.
