Geologic Forces of Nature
Geologic processes, are natural and play a fundamental role in shaping ecosystems.
Sinkholes and Subsidence
The normal processes of landscape development in karstic areas may include localized, and seemingly spontaneous, subsidence. In populated areas, sinkholes can be destructive to facilities and potentially life threatening. Most observed collapses occur in soils and sediments overlying karstic bedrock.
An unpredictable nature mixed with an ability to release massive amounts of energy make volcanoes extremely hazardous. The types of hazards that threaten an area will vary based on the type of volcano. Some hazards are local in scale, while others can affect the entire planet.
