  2. What is a ShakeMap? • Representation of ground shaking, not magnitude • Data gaps common due to lack of instruments • Predicted values added in these areas • Produced by USGS after earthquakes to assess possible damage and plan response • Modeling scenario earthquakes such as Shakeout • Map Types: • Peak Acceleration • Peak Velocity • Spectral Response • Rapid Instrumental Intensity Source: http://earthquake.usgs.gov/earthquakes/shakemap/sc/shake/Landers/

  3. What is a Seismic Hazard Map? • Probability of exceeding a certain amount of ground shaking, or ground motion, in 50 years • Hazard depends on magnitudes and locations of likely earthquakes, how often they occur, and properties of local rocks and sediments • Applications of Hazard Maps: • Building Codes • Highway bridge design • Insurance rates • Business and land-use planning • Estimations of stability and landslide potentials of hillsides • Construction standards for waste-disposal facilities • Retrofit priorities • Allocation planning of assistance funds for education and preparedness (FEMA) • Concerned general public Source: http://earthquake.usgs.gov/hazards/products/conterminous/2008/maps/wus/2hzSA.wus2pc50.jpg

  7. Earthquake Statistics Calculator • Calculates magnitude-frequency distribution of an earthquake catalog • Compares with Gutenberg-Richter Law • b = • Graph displays cumulative and incremental distribution • Useful for testing completeness and validity of a series of earthquakes within a given catalog Graph of Magnitude Frequency Distribution for Felzer Catalog
