Abstract

As the Pacific Northwest climate changes, extreme weather, such as intensifying storms, and a shift in the type of precipitation experienced with warmer winters causing more precipitation to fall as rain instead of snow, may lead to an increased frequency of landslides. There have been several recent landslides in Portland, noticeable to the public, particularly in areas of high elevation such as Council Crest, which stands at 1,073 feet. Additionally, residents of neighboring homes have observed changes in the landscape, including those on private properties. To better safeguard both public and private property, comprehensive research and mitigation efforts are required. This analysis looks at weather and slide trend data to determine if there is a correlation between the increase in storm intensity and the frequency of landslides in the Portland Metro Area. Opportunities for further study and the critical consideration of community safety are highlighted. Understanding the correlation between intensifying storm events and landslide occurrences is crucial for implementing effective mitigation strategies and ensuring the safety of residents in landslide-prone areas.

Analyzing Intensifying Storm Events Correlation to Landslide Frequency in Portland’s West Hills
