Berkeley Digital Seismic Network (BDSN)

The Berkeley Digital Seismic Network (BDSN) is one of operated by the Berkeley Seismological Laboratory. Operations are partially supported by the USGS. The BDSN is an array of high dynamic range, broadband seismometers with collocated strong-motion accelerometers. Data from these stations are transmitted to UC Berkeley using continuous telemetry and are analyzed for earthquakes. For current BDSN network information as well as individual station pages, please see the Berkeley Seismological Lab's BDSN pages.
