In Southeast they are. Over millions of years things have stabilized a bit but in the fall you can get some landslides, when we get most precipitation.
Unusual this time of year though. There was one a year or so ago in Glacier Bay which was one of the largest ever in N. America. LINK Image: http://i.huffpost.com/gen/685497/thumbs/r-GLACIER-BAY-LANDSLIDE-large570.jpg
We have them locally, mainly downtown. Avalanches are a bigger concern to us though.
In Lituya Bay, on the Western Edge of Glacier bay the largest wave ever witness occurred when a landslide caused by an earthquake caused a wave 1,750 feet high
. Some fishermen lived through the ordeal.
