Document Summary
A way in which events, such as volcanic eruptions, earthquakes, etc. affect. These processes are driven by energy and is derived from 3 sources. Produces slow convection in the solid but plastic mantle. Warms earth"s atmosphere and surface producing winds causing evaporation of water. Pulls rocks, soils, snows on mountains, and water that falls as precipitation to move downslope. Hazard: the probability that a specific damaging event will happen within a particular period of time. Used to focus on the physical agents and processes that are considered as threats (must be viewed negatively by humans) Natural hazards (earthquakes, tsunamis, volcanoes, floods, fires, etc. ) Risk: the product of the probability of a hazardous event and the expected damage if the event does occur. Considers the exposure to dangers, adverse or undesirable prospects and the conditions that contribute to danger. Risk = f (hazard, exposure, vulnerability, coping capacity) Vulnerability = susceptibility of people/property to a hazardous event.
