City of Pasadena and Caltech to Build Seismic Sensing Network

PASADENA, Calif.—The City of Pasadena and Caltech are teaming up to create a citywide fiber optic earthquake detector capable of mapping how temblors are shaking the city at millimeter-scale resolution. The work will take advantage of two currently unused—or "dark"—strands of Pasadena's fiber optic cable that stretch in a large loop around the city. Using a couple strands of fiber to measure seismic activity will gather data equivalent to over 30,000 seismometers. Only 11 traditional seismometers exist within the city... continue reading »"City of Pasadena and Caltech to Build Seismic Sensing Network"
