INSTRUCTIONS FOR DATA RETRIEVING

Due to large amount of data, the digitized earthquake
recordings are stored in a compacted data form and grouped by
earthquake events.  To unpack and use the data, the following
instructions need to be followed:

1. Copy all files in this diskette to a directory on the hard
   disk having at least 2 megabytes.

2. At the directory prompt, type PKUNZIP.EXE LSSTyy.ZIP then
   hit carriage return. Digitized data at each recording
   station are unpacked and ready for use.(Note: yy stands
   for the earthquake event number.  For instance, LSST07 for
   event number 7)

Note: Data files are named xxxx.yyz where
      xxxx is the station ID (e.g. FA1-1, DHB6 )
      yy   is the event number (e.g. 7 for event LSST07, and
           12 for event LSST12)
      z    is the direction of motion recorded (U, E, N for
           vertical, East-West, North-South, respectively)
