The Cascadia Subduction Zone is one of the most dangerous fault systems in North America — a 700-mile-long fault that runs off the coast of Oregon, Washington, and northern California. Scientists estimate that a full rupture of the Cascadia Subduction Zone could produce a magnitude 9.0 or greater earthquake, followed by a devastating tsunami that could reach the Oregon Coast within 15–30 minutes. It is not a question of if — it is a question of when. And when it happens, standard homeowner's insurance will not cover the damage.

The Cascadia Subduction Zone: Understanding the Risk

The last full rupture of the Cascadia Subduction Zone occurred on January 26, 1700 — just over 325 years ago. Geologists estimate that full ruptures occur roughly every 200–500 years, meaning the Pacific Northwest is well within the window for the next major event. Oregon State University and FEMA have modeled the potential impacts of a full Cascadia rupture, and the results are sobering: widespread structural damage across the Oregon Coast, tsunami inundation of low-lying coastal areas, and infrastructure disruption that could last months.

The good news is that earthquake insurance is available and, for many Oregon Coast homeowners, more affordable than they expect. The cost depends on your home's location, construction type, age, and foundation type — but for many Oregon Coast homes, earthquake insurance can be added for a few hundred dollars per year.

What Earthquake Insurance Covers

• Dwelling Coverage: Covers the cost to repair or rebuild your home after earthquake damage, subject to your deductible.
• Personal Property: Covers damage to your belongings — furniture, electronics, clothing, and other personal property — caused by earthquake shaking.
• Loss of Use: Covers additional living expenses if your home is uninhabitable after an earthquake — hotel, food, and other costs while your home is being repaired.
• Emergency Repairs: Some policies cover the cost of emergency repairs to prevent further damage after an earthquake.

Earthquake Insurance Deductibles: What to Expect

Earthquake insurance policies typically have higher deductibles than standard homeowner's policies — usually 10–25% of the dwelling coverage limit, rather than a flat dollar amount. For a home insured for $400,000, a 15% deductible would mean you pay the first $60,000 of earthquake damage out of pocket. This is why earthquake insurance is most valuable for catastrophic losses — total or near-total destruction — rather than minor damage.

When evaluating earthquake insurance, consider your home's replacement cost, your financial ability to absorb a large deductible, and the likelihood of significant earthquake damage in your specific location.
