Document Summary
Tsunami travel-times: plenty of time to send out a warning. You need to think about preparing before the earthquake (plan ahead) Secondly, know what to do during the earthquake. Third, you need to have education on what to do after the eq (shut off gas/water: try predicting earthquakes, long term: Therefore, short-term prediction is not likely to work. Y: number of landslides per day: 0. 01, 0. 1, 1, 10, etc. up to 1000. Line is diagonal (top left to bottom right) Example: la, california (9 major events in 1400 years, therefore recurrence interval of 160 years) Look for seismic gaps (gap= region along the fault where no earthquakes have been reported for a long period of time) these are high risk areas (the stored energy is not being released when it finally does, look out!) The fault is locked (i. e. san francisco area of san andreas fault: short term: Difficult to pin-point precise times of upcoming earthquakes because earthquake behavior is.
