What are the Preparedness Recommendations for a Cascadia Earthquake?
“Plan to be on your own
for at least 2 weeks"
-Emergency Management Division, WA
WHAT is the recommendation for preparing for a Cascadia Subduction Zone (CSZ) Earthquake?
Emergency Managers say to have an emergency plan and at least two weeks of supplies in order to shelter in place and take care of your family after a Cascadia earthquake. Having water, food and safety supplies will allow you to meet your basic needs instead of scrambling at a time of limited resources. We'll all likely be "camping" at home (with no water, electricity, sewer, cell service), so having life sustaining supplies on hand will make a world of difference.

WHY two weeks?
Subduction zone earthquakes are the largest on earth, which means 3-5 minutes of shaking. For comparison, California's San Andreas Fault earthquakes last about 15-30 seconds.
Most roads will be impassable, so it’ll take a couple of weeks for relief to even get to us. Imagine no electricity, running water or toilets for weeks or months. Cell phones probably won't work after the earthquake. Having two weeks of supplies will allow you to shelter in place take care of yourself until relief arrives.
WHEN will the earthquake happen?
Sadly, there’s no way to know when it will happen, only that it will. That’s how earthquakes work, there's no warning. We do know that once an earthquake strikes it's too late to prepare. The last CSZ earthquake was in 1700 and the Cascadia fault has been building up pressure ever since. Historically, the average time between Cascadia earthquakes has been 243 years.
Choose between our 3 levels of home earthquake kits. All home kits include two weeks of water storage, food and critical safety supplies. Our Comprehensive Home Kit mirrors the recommendations set forth in Oregon Office of Emergency Management’s Living on Shaky Ground publication and the American Red Cross, Cascades Region’s Prepare!
