Preparedness activities are designed to help save lives and minimize damage by preparing people to respond appropriately. Not using a product with potentially hazardous effects would be one way to prevent a hazard. Also called speed of onset. Richter Scale a logarithmic scale expressing the amount of energy released in an earthquake .
Risks are measures of the threat of hazards.
Saffir-Simpson Hurricane Scale measure of hurricane intensity and magnitude by scaling the storm based on central pressure, windspeed, storm surge, and potential damage. Landslides may occur, for example, if the shaking from an earthquake causes a mass of rocks and earth to shift beyond its angle of repose. Nuclear technology, pollution, and warfare are examples. Wind velocities can reach 200 miles per hour. They form as funnel clouds from thunderstorms and hurricanes.
