00:00Washington state officials are reviewing new tsunami modeling for the San Juan Islands.
00:04The model examines a potential earthquake in the Alaska Aleutian subduction zone.
00:09It shows wave amplitudes of 3 to 10 feet across the islands.
00:14East Sound has some of the highest measurements in the new model.
00:17Officials say the modeled inundation would be relatively limited.
00:20However, strong currents could still threaten waterfront infrastructure.
00:24Friday Harbor's docks could face complications from floating debris and currents.
00:28Emergency Management Director Brendan Cowan says residents should head uphill.
00:33He says high ground is generally close to homes across the county.
00:37A Cascadia subduction zone earthquake poses a different level of concern.
00:41County guidance says a tsunami could arrive within 45 to 90 minutes.
00:45Some high-risk areas could see water reach 20 feet above mean high tide.
00:50Officials say preparation is important because the islands could become isolated.
00:54More tsunami information will be added as the latest model is reviewed.
