Abstract: Objectives of this task are to conduct research on
seismic hazards, and to provide relevant input on the expected levels of these
hazards to other tasks. Other tasks requiring this input include those dealing
with inventory, fragility curves, rehabilitation strategies and demonstration
projects. The corresponding input is provided in various formats depending on
the intended use: as peak ground motion parameters and/or response spectral
values for a given magnitude, epicentral distance and site conditions; or as
time histories for scenario earthquakes that are selected based on the
disaggregated seismic hazard mapped by the U.S. Geological Survey and are
incorporated in building codes. The user community for this research is both
academic researchers and practicing engineers who may use the seismic input
generated by the synthesis techniques that are developed under this task for a
variety of applications. These include ground motions for scenario earthquakes,
for developing fragility curves and in specifying ground motion input for
critical facilities (such as hospitals) located in the eastern U.S.
