Do you know of any avalanches/icefalls triggered by this event around Denali or elsewhere?
I haven't heard of any. We don't have any significant snow yet at lower elevations, so there isn't much material to avalanche. Ice falls up on the glaciers would be a possibility, but climbing season is long since over on Denali for this year, so nobody is up there. There is the chance that someone flying over might see some snow, ice, or rock slides, but I haven't heard of any.
There were some monster slides after the 2002 M 7.9 quake on the Denali Fault. See
