Types of Natural Hazards  Volcanoes, floods, earthquakes, tornadoes, tsunamis, etc. –can occur:  without warning (e.g. earthquakes)  with warnings (e.g. satellite monitoring of cyclone tracks, or the presence of ground deformation at a volcano before an eruption)

Earthquake Hazards  These are important hazards to understand: –the natural hazard that on average kills the highest number of people per year ( 1 million during the past century) –commonly strikes without warning –no time for evacuation –not a predictable trend to earthquake numbers, magnitude or location  1000's of large earthquakes every year

San Francisco - Great Earthquake  Magnitude (1906)

How do we lessen the risk of earthquake activity?  Reinforce buildings  Education  Disaster plan

Tornado Quiz.

Tornadoes are also known as "twisters." They extend downward from the huge clouds of a severe thunderstorm. The winds that rotate within a tornado usually reach a speed of almost 400 miles per hour! A tornado often sweeps through an area quickly, but it can cause considerable destruction. There have been a number of remarkable reports of tornadoes. In one instance, a schoolhouse was demolished while the 85 students originally inside it were carried more than 400 feet with none killed. There was also a case of five railway coaches, each weighing 70 tons, lifted from their tracks.

We CAN’T stop the geologic processes Therefore, we must try to reduce the hazards through: scientific study population education changes in engineering/building practices
