Data Organization and Format || Download || Tables
The February 27, 2010 06:34 UTC Mw 8.8 Offshore Maule, Chile, Earthquake data provided by Nucleo Milenio International Earthquake Research Center of ICM-Mideplan and University of Chile are available via the NSMP ftp server in the folder (directory) "20100227_0634" (https://ca.water.usgs.gov/nsmp/20100227_0634). 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 for this event use the following file-naming convention:
| uncorrected acceleration: | S.C.._u.smc |
| corrected acceleration: | S.C.._a.smc |
| corrected velocity: | S.C.._v.smc |
| corrected displacement | S.C.._d.smc |
| response spectra: | S.C.._r.rs2 |
| Fourier amplitude spectra (f): | S.C.._f.fs1 |
where
S = 'CCSP' station code
C = SEED channel
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 "20100227_0634" on the NSMP ftp server, "https://ca.water.usgs.gov/nsmp/20100227_0634".
