The State of PNSN and Growth to Meet ShakeAlert Requirements

Room: Fifth Avenue

The Pacific Northwest Seismic Network (PNSN) is undertaking rapid growth to facilitate implementation of ShakeAlert in Oregon and Washington. Factors driving the build-out of the network include pace of growth and alignment with finite funding cycles, standards for low-latency data, telemetry diversity and topology, robustness of station design, and database management. While many of these factors are certainly not new to seismic network operations, the ShakeAlert requirements are driving revisiting of operational practices.

We will discuss the state of the PNSN, with emphasis on the ShakeAlert program. Description of station design as constrained by the variety of environmental conditions in the Pacific Northwest will be provided. Standardization of station components and data networking architecture will be discussed, with consideration of developing a sustainable network.

We continue to leverage regional resources that work towards a robust, resilient seismic network. Data transport via wireless communication networks in Oregon and Washington will be expanded to reach the last mile links to seismic stations. We partner with fiber networks and other internet service providers to link to our seismic network and to ensure redundancy in data transport. Large utility companies in the public and private sector help identify and host groups of new seismic stations. We value such partnerships to leverage and absorb best practices in operations, all with an eye on seismic network reliability and uptime.
