This directory contains the outputs from processing initial digitized products of strong-motion seismograms from the 1954 Fickle Hill earthquake.

Inputs are digitized traces in an x-y coordinate system retrieved by the DigitSeis software in .csv format. This software is available at: http://www.seismology.harvard.edu/research/DigitSeis.html

Outputs are time-associated using the lengths of the horizontal time-marks on the original images. The lengths of the marks and gaps in horizontal pixels are recorded manually in the files:
1954EurekaTiming.csv
1954FerndaleTiming.csv

The zero-line trend is also removed using a rolling mean, and the final time-associated zero-line trend removed data are output as .sac files. One .sac file is output for each components (6 in total across the two 3-component stations). Additionally a .pdf of the same name displays plots of the data at each step of the processing. These files (with both .sac or .pdf extensions) are:
EUREKA_N79E(.pdf/.sac)
EUREKA_S11E(.pdf/.sac)
EUREKKA_UP(.pdf/.sac)
FERNDALE_N46W(.pdf/.sac)
FERNDALE_S44W(.pdf/.sac)
FERNDALE_UP(.pdf/.sac)

Finally, the processing script (written in the Julia language) is included as a plaintext file as:
