Week5 - Sculpturing the Earths Surface

Visualizing Geology

Western Oregon is a region that is threatened by landslides that can cause hazards to the public’s safety, their natural resources, and infrastructure. The most hazardous areas are in the mountain terrains. Landslides are a common occurrence in Western Oregon. They can be very devastating to homes and businesses and each year millions of dollars are spent repairing the damage caused by landslides (Hofmeister, 2002).

Landslides are not individual events, they occur in conjunction with other factors. Landslides occur when a hill or mountain is unstable. Some of the factors that allow it to become unstable are erosion, addition of moisture, shocks and vibrations, and volcanic eruptions ("Why Do Landslides Happen?", 2011).
