Each event directory in the FTP site is named by the date then location of the event. Files for each event are then organized in directories by agency /contact. All data files are compressed(gzip) ASCII containing a 5 line header then data. The header contains:

  1. name/location, agency, id number, latitude N, longitude E, time interval in seconds and the number of data points.
  2. start time of the file in decimal day of year and calendar date/time, units of data and scaling factor.
  3. estimated tsunami travel time in hours from main earthquake shock and the time of the main shock, both in decimal day of year.
  4. the mean removed from the data and the write format for the data and a missing value flag if used.
  5. processing comments(may be blank).
For more descriptions, see the "areadme" files in the individual event directories. Postscript copies of the data table, maps and plots are found in the x_postscript directories. This information is also found in "1_readme.txt" in the database directory.
