1. Global Seismograph Network - GSN
DATES OF OPERATION: 19 Sep 1997 to Present.
SEISMOMETER TYPE AND ADC:
Streckeisen Model STS-1/VBB 3-component system for broadband and
very long period channels. Guralp Systems model CMG-3T 3-component
seismometer for short period channels continuously recorded at 40 sps.
Kinemetrics FBA-23 3-component force balance accelerometer recorded at
1 sps continuous mode and at 100 sps triggered mode. IDA MK7 data
acquisition system.
CALIBRATION EPOCH: 1997, 262 - Present
DIGITAL FORMAT:
16 bit integer data words for all broadband (20 sps) and mid-period
(5 sps) data. 32 bit integer words for very long period (0.1 sps) data
and synthesized long period (1 sps) data.
