To aid in earthquake identification, I have been generating one-page daily seismograms. These have reasonable resolution when printed out on my HP DeskJet 722C printer. The acquisition program is set up to record at 5 samples per second into a series of one-hour long files. The file names are numerically incremented, so that if the first file specified when recording is begun is 03000001.wdq, then the next one will be 03000002.wdq, etc. The acquisition PC is running Windows95, so I can copy the files to a floppy disk each day without interrupting acquisition.
Timing is still a big problem.
More on this later. To process the data I'm using a second Windows98 computer. Finally the program GSView is used to display and print the seismogram. If you want to try out this software, the programs I'm using are available. A readme.txt file describes the use of a few batch files that implement the routine operations.
