Document Summary
Risk probability of loss (deaths, injuries, damage, disruption of economic activity) as a result of a particular natural event. Prediction & forecasting statement that a particular natural hazard will occur with a given probability during a certain time frame in a specified geographic area. Mitigation efforts to reduce or minimize the effects of natural hazards on a community. Mitigation usually occurs after a prediction/forecast is made. Thus, we use statistics such as probabilities based on past trends. The most powerful earthquakes occur at convergent margins. 2 plates move away from each other and magma from the lithosphere rises and cools creating new crust. The movement of plates away from each other is known as rifting. Convergent margins occur when two plates slide into each other. There are 2 types of convergent margins: oceanic plate converges with a continental plate. The heavier, denser, oceanic plate slides under the lighter, buoyant continental plate subduction zone: two continental plates converge into each other.
