_/_ stations upgraded.
This map shows to date the progress of the SCSN stations upgrades as part of the American Recovery and Reinvestment Act (ARRA).
The USGS/ANSS/ARRA program is providing Government Furnished Equipment (GFE), and two-year funding for upgrading the Caltech/ USGS Southern California Seismic Network (SCSN). These improvements include:
- Upgrade dataloggers at seven TERRAscope stations
- Upgrade dataloggers at 131 digital stations and upgrade broadband sensors at 26 of these digital stations
- Upgrade balers at 47 stations with existing Q330 dataloggers.
- Upgrade SCSN metadata capabilities.
- Upgrade telemetry capabilities for both seismic and GPS data.
These upgrades will enable the SCSN to meet the ANSS Performance Standards more consistently than before. The new equipment will improve station uptimes and reduce maintenance costs. The new equipment will also provide improved waveform data quality and consequently superior data products. The data gaps due to various outages will be minimized, and latent data will be readily available through retrieval from on-site storage. Compared to the outdated equipment, the new equipment will speed up data delivery by about 5 sec, which is fast enough for earthquake early warning applications. The new equipment also has about a factor of ten lower consumption of power.
