Why Earthquake Insurance Matters in Washington—Lessons from the July 2025 Mount Rainier Swarm
Washington State sits atop significant seismic risks—from the Cascadia Subduction Zone to buried faults near Puget Sound. The recent July 8–11, 2025 earthquake swarm beneath Mount Rainier serves as a timely reminder. With hundreds of small quakes, including the largest since 2009 at magnitude 2.3, the swarm highlights the geological dynamism at our doorstep New York Post+5U.S. Geological Survey+5AP News+5.
While these events occurred safely deep (1–6 km below the summit) and were unnoticeable at the surface, they underscore a crucial truth: earthquakes can strike anytime, anywhere in Washington. As home insurance typically excludes seismic damage, homeowners are left exposed unless they purchase separate earthquake coverage NW Insurance Council+1Insurance Commissioner of Washington+1.

🏚 Why Earthquake Insurance Makes Sense for Washington Homeowners
- Seismic Exposure Is High
Western Washington’s proximity to active faults and the Cascadia Subduction Zone means even moderate events can damage buildings—and insurance can safeguard against that. - Standard Policies Don’t Cover It
Homeowners insurance doesn’t cover shaking damage, structural settlement, or landslides—but earthquake insurance does Temblor.netNW Insurance CouncilTemblor.net+5The Watchers+5Wikipedia+5. - Deductibles Reflect Risk
You'll typically see deductibles between 10%–25% of dwelling coverage in WA—higher than standard policies but manageable in exchange for broad protection Temblor.net+4NW Insurance Council+4Axios+4. - Preparedness vs. Crisis
Earthquake coverage isn’t just for the big “one.” Even swarms like Rainier’s, though shallow and small, can still cause cumulative damage or trigger building code upgrade requirements during repairs.
