A natural hazard is a natural event (for example, flood, volcanic eruption, earthquake, tropical storm) that threatens people or has the potential to cause damage, destruction and death.
Natural hazards are most commonly classified by the physical processes that caused them. Tectonic hazardsare created through the movement of the Earth’s tectonic plates. Hazards to humans created in the atmosphere, such as tropical storms, droughts and tornadoes, are atmospheric hazards. Hazards originating on or near the Earth’s surface, such as l...
Natural events, such as volcanic eruptions or earthquakes that occur away from humans and properties, are not considered natural hazards. They are considered natural hazards when they happen close to human populations and property. Hazard riskis the probability or chance that a natural hazard may take place. Different factors affect the hazard risk...
A natural hazard is an extreme event that occurs naturally and causes harm to humans – or to other things that we care about, though usually the focus is on humans (which, we might note, is anthropocentric). An extreme event is simply an unusual event; it does not necessarily cause harm.
Aug 16, 2019 · A geologic hazard is a naturally occurring, dynamic geologic process capable of causing damage, loss of property, and/or injury and loss of life. Geologic hazard processes can happen slowly over days or years, or have a sudden onset occurring in seconds or minutes.
Natural hazards can be classified into several broad categories: geological hazards, hydrological hazards, meteorological hazards, and biological hazards. Geological hazards are hazards driven by geological (i.e., Earth) processes, in particular, plate tectonics. This includes earthquakes and volcanic eruptions.
