This experiment recorded observations out to distances of about 
200 km along four lines (this is one of these lines). Briefly,
28 shots of which 3 were sea shots were recorded by about 20 
MARS type mobile seismic stations recording three components 
of ground motion and an external Radio Moscow time signal, all 
frequency modulated, on single track analog magnetic tape.  
20 shots were recorded with station spacing of around 5 km, 
while 8 small shots were recorded with a station spacing of 
1 to 2 km.

**Note:  For this particular line, small charges were fired in 
shallow holes at intervals of 30 km and the shots being observed 
in both directions.  The best data recorded in this experiment, 
from large shots fired at quarries were recorded along this line.
