This page documents our analysis of the impact of the low frequency site response, as applied to deterministic seismograms as part of the broadband simulation process.
Study 22.12 comparisons
Below are scatterplots comparing Study 22.12 low-frequency and Study 22.12 broadband results, at periods of 2-10 sec. Since the Study 22.12 LF results don't include site response and the broadband results do, this provides a way for us to examine the impact of the site response.
