Data Organization and Format || Download || Tables
The March 17, 2014, 13:25 UTC, Mw 4.4, Encino, California Earthquake data recorded by the USGS National Strong-Motion Network (NSMN) are available via the NSMP ftp server in the folder (directory) "20140317_1325" (https://ca.water.usgs.gov/nsmp/20140317_1325). 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. Data from other sources are available at the Center for Engineering Strong-Motion Data (CESMD).
The file names for the data have the following form:
| uncorrected acceleration: | S.C.N.L_u.smc |
| corrected acceleration: | S.C.N.L_a.smc |
| corrected velocity: | S.C.N.L_v.smc |
| corrected displacement | S.C.N.L_d.smc |
| response spectra: | S.C.N.L_r.rs2 |
| Fourier amplitude spectra (f): | S.C.N.L_f.fs1 |
S = Station code
C = SEED channel
N = Network Code
L = Location code
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 amplitude 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.
To facilitate downloading the data, the data have been compressed into PC compatible ".zip" format. The same zip file is located in the "zips" folder in "20140317_1325/" on the NSMP ftp server, "https://ca.water.usgs.gov/nsmp/20140317_1325".
