In other words when the hazardous threat actually happens and harms humans, we call the event a natural disaster. A natural hazard is a threat of a naturally occurring event will have a negative effect on humans. Geophysical - Earthquakes, landslides, tsunamis and volcanic activity. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. People cannot prevent the natural processes but can take steps to minimize the hazards (e.g., build flood walls). A case in point is the question of when fog (a natural hazard) becomes smog (quasi-natural). 7.

The Landslide Hazards Program at the WGS is producing landslide inventories for densely populated areas. A few of these include saturation of slope material (rainfall), seismic activity (earthquakes and volcanoes), undercutting of cliffs and banks by waves and rivers, removal of vegetation, and modification of slopes. The identification of landslide-prone areas is an essential step in landslide hazard assessment and mitigation of landslide-related losses. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Be alert when driving. Hazard and risk The difference between hazard and risk is: • A hazard is a source of potential harm or a situation with a potential to cause loss. The loess (wind deposited silt) is strong enough to form near vertical slopes which are easily weakened during seismic activity. Other natural hazards such as floods and wildfires can result from . They are among the greatest threats volcanoes pose to people and property. Landslide.
