System Monitoring, Telemetry Quality Control, and Planning Tools for Scsn
Description:
The Caltech/USGS Southern California Seismic Network (SCSN) is a modern digital ground motion seismic network. It develops and maintains data acquisition and delivery systems for rapid earthquake information products like earthquake origins, magnitude, and ShakeMap as well as for Earthquake Early Warning (ShakeAlert).
We present recent and ongoing innovations in telemetry, system monitoring, and planning tools that keep the network running efficiently and provide timely, high-quality streaming data. We also are developing a quantitative approach to evaluate station locations for the ShakeAlert mission that allows us to calculate station expected contributions in terms of likelihood to detect earthquakes and benefit to people nearby.
Most SCSN sites deliver data continuously to both cloud (AWS) and terrestrial servers located on the Caltech campus in Pasadena. The second data acquisition path allows SCSN to keep processing waveforms during extreme events. Redundant data flows make delivery more disruption tolerant integrating flows for data archiving but requires a special approach to handle arriving duplicate packets.
We also use a bi-axial shake table to test the instrument and telemetry performance during shaking. By recreating past seismic events and analyzing system responses, we can design a more robust seismic site and work with field engineers on the installation improvements.
We are developing tools to monitor the system state of health as well, including regular measurements of data transport latency and telemetry link bandwidth from each datalogger to the data center. Using these results, we analyze performance of new and established connections and track if they meet our latency and bandwidth targets.
