Washington State is subject to numerous geologic hazards—hazards with the potential to affect thousands of people include earthquakes, tsunamis, and volcanic activity. Landslides (not shown) also significantly

affect Washington’s citizens on a local level.

This map was created in order to provide emergency managers, land-use planners, and other decision-makers with the ability to identify known geologic hazards in their regions. The map shows

volcanic hazard areas (purple), mapped faults (red lines), tsunami hazard study areas (green), tsunami evacuation brochure areas (yellow), and tsunami and lahar warning sirens (red circles).

It is a generalized, small-scale view, and is not meant to show site-specific information. For more detailed hazard data, please refer to the references given on the map.

EarthquakesThere are numerous faults in Washington that have the potential to produce damaging earthquakes. The largest fault is the Cascadia subduction zone—an M9.0 earthquake on this fault is predicted to cause damage of about $49 billion (Washington State Emergency Management Council—Seismic Safety Committee, 2012). Earthquakes directly cause damage by intense shaking and liquefaction, and create equally significant secondary effects, such as tsunamis and landslides.

TsunamisA Cascadia subduction zone earthquake will not only cause shaking damage, but will likely result in tsunamis that will affect coastal communities. In Japan, the 2011 Tohoku tsunami caused $300 billion in total damages and 15,891 fatalities. The Division of Geology and Earth Resources partners with other agencies to produce modeling of tsunami inundation in order to better prepare communities in planning for tsunamis along our coast. Planning for tsunamis includes producing tsunami evacuation brochures, installation of All Hazard Alert Broadcast (AHAB) tsunami sirens, and the design and construction of vertical tsunami evacuation structures in low-lying coastal communities.

VolcanoesThere are five large stratovolcanoes in Washington State, and all have the capability of producing large eruptions, volcanic mudflows, and ash fall. The 1980 eruption of Mount St Helens killed 57 people and cost at least $2.9 billion in 2016 dollars. Populous communities downstream of Mount Rainier are most vulnerable to volcanic mudflows (lahars)—lahar sirens are in place in Pierce County and evacuation planning there is ongoing.
