Document Summary

Natural hazards hazards affect millions of people around the world each year. Processes and natural hazards natural hazards can arise from three main processes: Internal forces within the earth driven by the internal energy of the earth currents that drive the magma eg. plate tectonics earthquakes, volcanoes, tsunamis: external forces on earth"s surfaces. More related to weather all driven by the sun"s energy eg. atmospheric effects/hazards: gravitational attraction driven by force of gravity, downslope movements eg. landslides, avalanches. Definitions natural hazard: a natural process that poses a potential threat to people and property; nothing you can do about it. Hazards are potential risk: the probability of an event occurring multiplied by the impact on people and property (probability x impact) higher risk hazards focused on more in the media. 1 disaster: a brief event that causes great damage or loss of life.
