The Role of Hazard Definition in CBE |

The Hazards Definition thrust area of the MAE Center has
as its primary task the refinement of hazard
characterization. Hazard definition is one of the
initial input variables into the CBE flowchart and
improved hazard characterization will allow more
accurate applications of the CBE procedure. |

There are seven projects within the Hazards Definition thrust area: HD-1 Involves calculation of synthetic ground motions and response spectra for scenario earthquakes. This project will bridge the gap between seismological and geotechnical investigations and will feed directly into other core thrust areas. HD-2 Involves characterizing seismic source parameters in continental intraplate regions and reducing the uncertainty involved in this process. Seismically capable faults will also be identified. HD-3 Is the intraplate testbed for ground motion data and the seismic and GPS data bases will establish ground truth for other HD projects. HD-4 Investigates the source parameters and the wave propagation effects of the 2001 Bhuj, India earthquake, a large intraplate earthquake located in a geological setting that is very similar to the Mississippi embayment. HD-5 Investigates the effects of attenuation on the propagation of strong ground motion in between the seismic source and the receiver. This project will also involve the collection of high frequency seismic wave data from controlled explosions. HD-6 Will investigate the effects of the recording site on strong ground motions. Emphasis will be placed on the effects of very deep soil deposits. HD-7 Will investigate the effects of ground deformation. Linear and non-linear dynamic response of near surface soils will be characterized with emphasis on liquefaction and slumping. Each project will be discussed in detail and we will examine how the projects integrate to produce important and useful parameters to the CBE procedure. |
