Earthquake Risk in Seattle and the Puget Sound

Seattle and the Puget Sound region are at significant risk of a major earthquake. The region is located in the Cascadia subduction zone, where the Juan de Fuca plate is sliding beneath the North American plate. This subduction zone has produced some of the largest earthquakes in North American history, including the 1906 San Francisco earthquake and the 1964 Alaska earthquake.

Scientists estimate that there is a 37% chance of a magnitude 7 or greater earthquake occurring in the Cascadia subduction zone within the next 50 years. Such an earthquake would cause widespread damage and loss of life in Seattle and the Puget Sound region.

What to expect during a major earthquake

The shaking from a major earthquake can last for several minutes and be strong enough to cause buildings to collapse, bridges to fail, and roads to buckle. Ground shaking can also trigger landslides and liquefaction, which is the process by which loose, water-saturated soil turns to liquid and flows like quicksand.

In addition to ground shaking, earthquakes can also generate tsunamis, which are large waves that can inundate coastal areas. Seattle and the Puget Sound region are at risk of tsunamis from both the Cascadia subduction zone and from earthquakes that occur in distant parts of the world. RTI

How to prepare for an earthquake

The best way to prepare for an earthquake is to have a plan in place. This plan should include the following:

• Know your risks. Learn about the earthquake hazards in your area and identify safe places to take shelter during an earthquake.
• Make a plan with your family. Discuss your earthquake plan with your family and make sure everyone knows what to do in the event of an earthquake.
• Put together an emergency kit. Your emergency kit should include food, water, first aid supplies, and other essentials that you will need in the event of an earthquake or other disaster.
• Secure your home. Make sure that your home is properly secured to prevent damage during an earthquake. This includes strapping down water heaters and other appliances, and securing cabinets and other furniture.

What to do during an earthquake RTI

If you are indoors during an earthquake, drop to the ground, take cover under a sturdy table or desk, and hold on. Stay under cover until the shaking stops. If you are outdoors, move away from buildings, trees, and other objects that could fall on you.

What to do after an earthquake

After an earthquake, check for injuries and provide first aid if needed. Be aware of the possibility of aftershocks, which are smaller earthquakes that can occur after a major earthquake. If you are in a coastal area, be alert for a tsunami warning.

Conclusion

Seattle and the Puget Sound region are at significant risk of a major earthquake. It is important to be prepared for an earthquake by having a plan in place and by securing your home. If you are caught in an earthquake, drop to the ground, take cover, and hold on.
