Document Summary

Generic approach to risk analysis and risk management. A: risk analysis (add venn diagram: understand the hazard (in general, determine the risk from that hazard for the region of interest. Risk = (probability of hazard)* (severity of hazard) What is their nature: look on the ground, and from the air (and space!) There can be hidden faults: set up seismometers to help locate faults. Only useful for faults that have moved since seismometers were set up. Some are inactive (have not moved in last 2 million years. Some are potentially active (has moved in last 2 million years. Some are active (has moved in last 10,000 years) All the way from small ones, up to very big ones (i. e. the st. lawrence. Normal dip slip: pressure goes down the ramp. See part (b) (b) study history of earthquakes in the area: set up seismometers. Gives an idea of which faults are most active.
