Vancouver, Washington

15 Land Tracts in Clark County , Lower Columbia-Sandy Watershed

Vancouver, Washington faces relatively high natural disaster and climate risks due to its location. The area is prone to flooding from heavy precipitation, with an average of over 1,000 mm per year, increasing the risk of flash floods and landslides. Additionally, the high humidity levels and moderate lightning risk pose a threat to the community. The city's proximity to the Cascade Range also increases the risk of volcanic activity, as Vancouver is located near several active volcanoes such as Mount St. Helens.

The region is situated in close proximity to the Pacific Ocean, making it vulnerable to tsunamis and storm surges in the event of a major coastal disaster. Vancouver is also located near several fault lines, increasing the risk of earthquakes. The combination of geological features such as fault lines, mountain peaks, and water bodies in the area heightens the overall hazard risk. Past events like the eruption of Mount St. Helens in 1980 serve as a reminder of the potential for natural disasters in the region.

The city's large population of over 500,000 people and its relatively low preparedness levels for certain hazards further elevate the risk factor. Emergency response and evacuation plans should be in place to mitigate the impact of potential disasters. Improved infrastructure and community resilience measures are essential to enhancing the city's readiness for natural disasters and climate-related risks.
