Live in Bremerton right by the Manette Bridge. / Moderate shaking (MMI V) : I guess that is what woke me up right then. I just thought someone was knocking on the door. Didn't feel any shaking by the time I awoke. I live right at the corner of the Port of Washington narrows and the Sinclair inlet. | One user found this interesting.
Edmonds Way, Edmonds WA. / not felt / 1-2 s : Sounded like loud knocking on the wall... No shaking that i noticed. Edmonds, WA.
