Amount of data

|---|---|
| Status information from SAM/MEG | 1.31 MB/day (including GCF header) |
| Seismic data | 3 channels x 2 systems x (100 + 20 sps) x 2 bytes (typical) x 3600 s x 24 hr + header = 121 MB/day |
| Slow seismic data | 4 channels (mass, position, temperature) x 2 systems x 4 sps x 1 byte x 3600 s x 24 hr = 2.68 MB/day |
| Total of 125 MB/day = 590 days to fill 72-GB hard disk storage in the SAM | |
Note: SAM = storage acquisition module, MEG = multiple-access expandable gateway, GCF = Guralp Compressed Format.
