This U.S. Geological Survey (USGS) Project Grant award under the Earthquake Hazards Program Assistance (CFDA 15.807) provides $157,886.66 to Fiber Sense US LLC to research, develop, and begin productizing an innovative fiber-optic distributed acoustic sensing (DAS) method using telecommunications cables to advance seismic hazard analysis in urban areas.
The key activities and deliverables include: 1) Generating and delivering a dataset of 1,500 earthquake recordings from the San Francisco Bay Area to the research community and USGS via a cloud endpoint, 2) Developing a new technique for earthquake detection based on spatial cross-correlation beamforming of DAS array data, 3) Developing and testing a method to measure peak ground acceleration using DAS, and 4) Measuring end-to-end notification latencies for DAS-based earthquake alerting. The expected outcomes of this 2-year project aim to advance the use of novel DAS technology in earthquake early warning systems.
