Modern Tools and Approaches to Earthquake Monitoring and Product Generation at the Southern California Seismic Network (SCSN)
Description:
Earthquake monitoring systems used at regional seismic networks currently run software on local servers that process continuous seismic data in real-time and output earthquake products such as event origins, focal mechanisms, moment tensors, ShakeMaps, and waveforms. The Southern California Seismic Network (SCSN) is exploring ways to generate and distribute earthquake products with modern software technologies such as cloud-native services in Amazon Web Services (AWS), serverless computing, containers, and Infrastructure as Code (IaC). These technologies have potential to improve the timeliness of earthquake product delivery for end-users, as well as expedite testing and incorporating new scientific algorithms, software, and other infrastructure into operational earthquake monitoring. We discuss software infrastructure design choices, strategies for integration with existing monitoring systems, and cost considerations for cloud operation. We also explain how SCSN is using cloud-based tools and services for earthquake monitoring and product generation, such as AWS lambda functions for auto-scaling computation on large incoming data requests; IaC tools for setting up, configuring and tearing down computing resources; Docker containers for testing and executing software; and AWS Open Data for allowing public access to SCSN continuous waveform data archives.
