These hazards only become hazards when they impact life or property and are very much a normal part of environmental processes. Ramsey County is at risk of a variety of geologic hazards, the most common of which are: • Landslide: The downward movement of a mass of rock, soil, and debris along a slope or cliff face. This movement can range from gradual, slow displacement to rapid, catastrophic events. Landslides are typically triggered by factors such as heavy rainfall, earthquakes, volcanic activity, or human activities that destabilize slopes. Examples of landslides include rock falls and debris
