Geologic Hazard

A geologic hazard is an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis and landslides. A geologic hazard is one of several types of adverse geologic conditions capable of causing damage or loss of property and life. These hazards consist of sudden phenomena and slow phenomena: Sudden phenomena include: avalanches (snow, rock, or air & snow) and its runout. Volcanic eruptions are one of the planet’s most dramatic and violent natural hazards. They typically occur 50 to 60 times each year, when magma rises through cracks or weaknesses in Earth’s crust.
