Abstract
For the assessment of risk of any area three components are necessary viz., Hazard, Exposure and Vulnerability. While most of the times Exposure and Vulnerability are easy to obtain compared to Hazard. For Hazard estimation, real ground motions are required. However, in highly seismic areas with less number of recorded ground motions, synthetic ground motions are quite helpful. Geophysical parameters play a vital role in generating synthetic accelerograms. The main objective of this paper is to propose geophysical parameters such as ground motion prediction equation, kappa parameter and Q parameter for Alaska region. Though, the above parameters are partially available for Alaska, comparisons are made with similar site conditions.
