Does Washington have earthquake building codes? Adoption of 2003 building, mechanical, fire, and plumbing codes brings Washington State’s building codes to the highest level nationwide and they address the state’s seismic hazard.
How are buildings assessed for earthquake safety? When dealing with a population of buildings, the first step is to perform a quick survey using Rapid Visual Screening of Buildings for Potential Seismic Hazards (FEMA 154). The next step is to evaluate the building using Seismic Evaluation of Existing Buildings (ASCE/SEI 31-03).
Is Washington state prone to earthquakes? Large earthquakes are likely to happen in Washington during your lifetime. Most of the populated areas of the state have a 40–80% chance of having an earthquake in the next 50 years.
Is Seattle in a seismic zone? Crustal earthquakes are expected on the Seattle Fault Zone, which is the primary but not only source for this type of quake in Seattle. An example of a crustal earthquake is the magnitude (M)6.2 Christchurch, New Zealand earthquake that occurred in 2011.
