Anchorage / not felt : Never felt it
Portland / Light shaking (MMI IV) : I was on a boat the Royal Viking at Akutan harbor. Been on two other boats when I felt the shutter. San Pedro harbor California, and Ohau Hawaii. It's different but I knew what it was.
Southwest Anchorage, AK (1239.7 km NE of epicenter) [Map] / not felt : Slept through it.
Amanak island / Light shaking (MMI IV) : I was awake and in bed. Felt slight trembling then more abrupt shaking. No damage to report.
Akutan teacher housing. (22.5 km NNE of epicenter) [Map] / Moderate shaking (MMI V) : Pretty unsettling. We thought it was the ferry hitting harder than usual against the dock. My animals were concerned. Lights swinging and dishes rattling. A little hard to walk in house. (reported through our app)
