About the CESMD

The Center for Engineering Strong Motion Data (CESMD) is a cooperative center established by the US Geological Survey (USGS) and the California Geological Survey (CGS) to integrate earthquake strong-motion data from the CGS California Strong Motion Instrumentation Program, the USGS National Strong Motion Project, and the Advanced National Seismic System (ANSS). The CESMD provides raw and processed strong-motion data for earthquake engineering applications.

Specifying Valid Data Ranges in Station Files

Below is a sample station file with 5 stations:

#BBP Station List
#SLong    SLat     RSN   Vs30(m/s) LoPass_Freq(Hz) HiPass_Freq(Hz)
-121.800 37.450  24017   519 0.1750  111.1111
-121.769 37.373  24018   471 0.3750  111.1111
-121.871 37.414  24011   363 0.1500  111.1111
-121.808 37.347  24006   377 0.1875  111.1111
-121.643 37.342  24026   710 0.3875  111.1111

The 4th and 5th columns are used to specify at what frequencies the observation data is valid for each station. In this particular example, all stations have data valid up to above 100Hz (111.11Hz to be exact). But lower frequencies vary for each station.

In the Broadband Platform, data outside the range provided is discarded and not used for the Goodness-of-Fit plot.
