Lake Oswego, Oregon, located in Clackamas County, faces various natural disaster risks due to its proximity to major geological features. The city is situated in the Willamette hydrologic region, which is known for its high volcanic risk. The area is also close to the Cascade Range, increasing the potential for earthquake risks. Additionally, Lake Oswego is near the Lower Willamette River, putting it at risk for flooding events, especially during periods of heavy precipitation.

The climate in Lake Oswego is characterized by relatively low temperatures and high humidity levels, making the area prone to heavy precipitation events. The city's location in the Pacific Northwest region further exacerbates these risks as the region is known for its frequent rain and snowstorms. The surrounding mountain peaks also contribute to the potential for landslides and avalanches, impacting the safety of residents in the area.

Moreover, Lake Oswego's proximity to the Pacific coastline increases the risk of tsunamis and storm surges, especially during periods of heightened hurricane activity. Historical events such as the Columbus Day Storm of 1962, which caused widespread damage in the Pacific Northwest, serve as a reminder of the potential hazards faced by the city. Overall, the combination of geological features, climate conditions, and historical events underscores the importance of comprehensive natural disaster preparedness and risk mitigation strategies in Lake Oswego, Oregon.
