1. Overview of the Ketchikan Landslide

The Ketchikan landslide refers to a specific geological event that occurred in the region, characterized by the sudden movement of earth and rock down a slope. These events are typically triggered by a combination of factors, including heavy rainfall, erosion, and seismic activity. Understanding the nature of the landslide is crucial for assessing its impact on the local community.

1.1 Definition and Types of Landslides

Landslides can be classified into several types, including:

• Rotational slides: Occur when a mass of earth rotates along a curved surface.
• Translational slides: Involve the sliding of rock or soil along a flat surface.
• Debris flows: Rapid movement of a mixture of water, soil, and rock.
• Rockfalls: Sudden falling or rolling of rock from a cliff or steep slope.

2. Causes of the Ketchikan Landslide

Several factors contribute to the occurrence of landslides in Ketchikan. The most significant causes include:

• Heavy Rainfall: Ketchikan experiences significant rainfall, which can saturate the soil and increase the likelihood of landslides.
• Geological Composition: The region’s geological makeup, including steep slopes and loose soil, plays a crucial role in landslide susceptibility.
• Human Activity: Construction and excavation can destabilize slopes, leading to landslides.
