Notice of Intent: Partial Support of Joint USGS-Caltech Southern California Seismic Network | USGS FA 20 0037

Opportunity Information: Apply for USGS FA 20 0037

This grant opportunity is a Notice of Intent from the U.S. Geological Survey (USGS) to make a cooperative agreement award to the California Institute of Technology (Caltech) to partially support the Joint USGS-Caltech Southern California Seismic Network (SCSN) under the Advanced National Seismic System (ANSS). The overall purpose is to sustain and strengthen the day-to-day earthquake monitoring backbone for Southern California by ensuring the seismic network continues operating to national ANSS standards and continues delivering high-quality data products that support public safety, science, and hazard response.

The core work supported by the agreement centers on operating and maintaining the region's seismic stations and the full set of station metadata required to make those stations useful and trustworthy within ANSS. That includes routine station operations, equipment upkeep, repairs, calibration, and maintaining accurate, standardized descriptions of each station (for example, precise locations, instrument types, response characteristics, and configuration history). A major emphasis is that both waveform data (the raw ground-motion recordings) and accurate station metadata must be delivered reliably to other ANSS networks and to ANSS-designated archives, so the broader national system can use Southern California data seamlessly and in near real time.

Another major objective is compliance with ANSS-approved software standards so that data and information move efficiently through the system and remain interoperable. In practical terms, this means using shared approaches and approved tools for data acquisition, processing, formatting, and distribution, which helps ensure that ANSS products and services remain robust, consistent across regions, and usable by many different downstream users ranging from scientists to emergency managers.

The opportunity also highlights the production of authoritative earthquake catalogs and related products that meet ANSS standards. These catalogs typically include earthquake source parameters such as origin time, location, depth, and magnitude, along with other derived products and services ANSS depends on. The language "authoritative" signals that the SCSN is expected to produce official, quality-controlled earthquake information for the region rather than informal or experimental outputs.

A specific system development and coordination role is also spelled out: Caltech will contribute to the operation and development of the Station Information System (SIS). SIS is described as the tool for station inventory control and for describing and maintaining station metadata. The agreement expects Caltech to work with ANSS leadership and the ANSS National Implementation Committee (NIC) toward using SIS or populating it so that the national program has standardized, up-to-date information about station assets and configurations. Beyond technical tasks, the work includes coordinating seismic monitoring activities with ANSS management and other ANSS participants, reinforcing that the SCSN is part of a national enterprise rather than a standalone regional network.

The Notice of Intent justifies why Caltech is the intended recipient by describing unique qualifications and practical constraints. It emphasizes that the principal investigators and Caltech personnel have deep, specialized expertise in Southern California seismicity and deformation and extensive experience operating seismic networks. It also notes that Caltech has an established, capable network staff and that specialized monitoring equipment has already been deployed by Caltech in the target region. Some of the key sensors and central recording and computing infrastructure are university-owned and would not be available through another provider, and the current telemetry and data reception pathways are already routed to university facilities. Moving those receiving points and telemetry systems to a different organization would be expensive and time-consuming, potentially disrupting monitoring continuity.

Administratively, this is a discretionary funding opportunity from the USGS in the natural resources activity category, offered as a cooperative agreement (which generally implies substantial involvement and collaboration between the federal agency and the recipient compared to a standard grant). The listed eligible applicant type is public and state-controlled institutions of higher education, and the intended awardee is Caltech as stated in the notice. The opportunity number is USGS FA 20 0037, the CFDA number is 15.808, the posting/creation date is 2019-12-11, and the original closing date is 2019-12-25. The award ceiling is listed as $13,400,000, and the expected number of awards is not specified in the provided text.
