DATES OF OPERATION:     13 Apr 1992 to 29 Jun 1997.

SEISMOMETER TYPE:
Streckeisen Model STS-1V/VBB; STS-1H/VBB.

DIGITAL FORMAT:
SEED(IRIS); SEED, GSEV2.X, MK2, CA (CNSDC)

EVENT DETECTOR ALGORITHIM:

COMMENTS:
The station had operated with Standard Station Network equipment (3 orthogonal 
WIlmore MarkII short period seismometers and 3 orthogonal Spregnether "Columbia"
long-period seismometers-photographic recording) from 18 October 1961 to 11 May 
1989, and then Regional Station Network equipment (one short period vertical 
Geotch S-13 seismometer - heat sensitive paper recording from 11 May 1989 to 29
