The Seattle Basin is a 6 to 7 km deep basin, formed by geologic processes and earthquake faults, filled with soil and soft rock. These sediments within the basin amplify earthquake motions, as we saw from earthquake ground motion recordings and damage patterns during the Nisqually earthquake. These amplified motions primarily affect taller buildings.
