Seaside Oregon is specifically identified by FEMA and Oregon emergency management as one of the most tsunami-vulnerable communities in the continental United States. The city sits at near sea level on the Necanicum River estuary directly on the Pacific coast — tsunami modeling shows Seaside could be inundated by up to 100 feet of water in a major Cascadia earthquake. The community has limited high ground and escape routes. Oregon has invested heavily in tsunami vertical evacuation structures for Seaside given the extreme vulnerability.
