Data Organization and Format

The December 13, 2002 03:16 UTC Md 3.7 Kailua, Hawaii Earthquake data recorded by the USGS National Strong-Motion Network (NSMN) are available via the NSMP ftp server in the folder (directory) "20021213_0316" (https://ca.water.usgs.gov/nsmp/20021213_0316).    The time series provided are available in uncorrected acceleration, corrected acceleration, corrected velocity, corrected displacement, response spectra (relative displacement, relative velocity, pseudo-velocity, and absolute acceleration), and Fourier amplitude spectra of corrected acceleration.  All of the data are in SMC format.

In a departure from previous file-naming conventions (where for a particular channel the different the time series data all had the same filename, and thus required separate directories for each data type), the file names for the data have the following form:

where 'RRRR' is the four-digit recorder serial number (including leading 0's), 'c' is the channel number of the recorder ('a' corresponds to channel 1, 'b' to channel 2 , etc), the '_x' is used to identify the data type, and the suffix refers to the data format (rs2 and fs1 are valid SMC format types recognized by the BAP processing program.

The data are stored in two directories: uncorrected (only uncorrected acceleration) and corrected (all of the corrected and processed data, including acceleration, velocity, displacement, response spectra and Fourier ampliude spectra. This convention for organizing the data was implemented to avoid confusion between the directory names (Vol1, Vol2, … Vol6) previously used for some earlier events and the standard conventions for Volume1, Volume2 and Volume 3 processing.

Information on how the data are processed can be found in the section on DATA PROCESSING.  Note that these data were processed using an acausal Butterworth locut filter.
