Natural Disaster Risk in Shaw Island

Natural Hazard Profile: Shaw Island, Washington

Shaw Island, in San Juan County, is a small unincorporated community situated in the Pacific Northwest. Its oceanic climate brings mild, rainy winters west of the Cascades and semi-arid conditions to the east, and in particular a critical wildfire period in eastern Washington each summer. These conditions collectively define the natural hazard environment that Shaw Island residents and property owners must navigate.

According to FEMA's National Risk Index, Shaw Island carries an overall risk score of 4.7/10, placing it in the moderate category. Tsunami risk is the primary coastal hazard, driven by the area's proximity to seismically active offshore zones capable of generating ocean waves that inundate low-lying coastlines. The area also faces notable exposure to volcano and coastal flood.

Within Washington, Shaw Island's risk is, slightly below the 5.8/10 state average. Nationally, it ranks near the U.S. national average of 4.5/10. FEMA's analysis of San Juan County identifies tsunami as the foremost hazard, followed by volcano and coastal flood. These rankings reflect the relative frequency and severity of each hazard type in the local environment.

Shaw Island'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.
