Certainly normal for Alaska. Being on the Rim of Fire makes for some shaky ground. Although we had a 4.5 last week early in the morning and I didn't feel it even though it was about 35 miles to the epicenter. I was evidently in a deep sleep mode. We get them all the time and there are lots that you don't actually see anything move, but sort of feel the sensation. Only the smaller ones of course.
I was in Anchorage for the 64 one. Really don't want to do that again.
