Geological hazards are natural events caused by the Earth's processes that can lead to significant damage or loss of life. Common examples include earthquakes, landslides, volcanic eruptions, and tsunamis. These hazards often occur due to the movement of tectonic plates, which can create stress in the Earth's crust. Understanding geological hazards is crucial for disaster preparedness and risk management. By studying the history and patterns of these events, scientists can help communities develop plans to minimize their impact. This includes creating early warning systems and implementing building codes that enhance safety in areas prone to hazards like earthquakes and landslides.
