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/

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 publicSource: http://earthquake.usgs.gov/hazards/products/conterminous/2008/maps/wus/2hzSA.wus2pc50.jpg

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
