Natural Disaster Risk in Lilliwaup

Natural Hazard Profile: Lilliwaup, Washington

Located in the Pacific Northwest in Mason County, Lilliwaup is a small unincorporated community. The oceanic climate that characterizes this part of Washington — marked by mild, rainy winters west of the Cascades and semi-arid conditions to the east — directly influences the types and severity of natural hazards present, making Lilliwaup a community where hazard awareness has real practical value.

Lilliwaup's overall natural disaster risk is rated 5.5/10 (Moderate) by FEMA's National Risk Index. Coastal tsunami exposure is the dominant hazard concern, with the regional tectonic environment capable of generating both local and distant-source tsunami waves. Secondary hazards include earthquake and landslide.

Relative to other U.S. communities, Lilliwaup's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.8/10 state average. The hazard distribution here is led by tsunami and earthquake, as measured by FEMA across Mason County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Lilliwaup's moderate risk profile means that while catastrophic events are less frequent, they do occur. Standard homeowners insurance typically covers many common hazards here, but confirming that tsunami exposure is adequately protected is a worthwhile step for property owners.
