Abstract

The Oregon coastline along Highway 101, near Beverly Beach, has been and continues to be affected by many costly and life threatening landslides that are caused by a combination of various geologic conditions including steep topography, structural geology, seasonal increases in sediment poor pressure, and the constant possibility of being triggered by earthquakes. Landslides in this area pose a serious threat to people and property, therefore these threats must be constantly monitored and analyzed based on current and past landslide behavior to help predict and prepare for future landslides. The Johnson Creek landslide, that continues to show movement, has cost considerable damages and is continually monitored because of its damaging affects on U.S. Highway 101. There has been significant research of past landslides in the area as well as potential landslides. Learning about these slides is of utmost importance due to large-scale earthquake threats, such as the magnitude 9 quake in 1700. If an earthquake happens it is likely that landslides will be triggered causing massive damages and blocking evacuation routes of possible incoming tsunami as well as slow down or block any incoming disaster relief.
