Berkeley Digital Seismic Network
The BDSN is an array of high dynamic range, broadband seismometers with collocated strong-motion accelerometers in northern and central California. BDSN Overview...
Hayward Fault Network
The NHFN is an array of borehole instrumentation deployed in the San Francisco Bay Area, with the goal of monitoring microseismicity on the Hayward fault. The borehole stations are deployed along the fault at free-field and Bay Area bridge locations. NHFN Overview...
Mini-Plate Boundary Project
The Plate Boundary Observatory (PBO) component of EarthScope is a geodetic observatory designed to study the three-dimensional strain field resulting from deformation across the active boundary zone between the Pacific and North American plates in the western United States. The observatory consists of arrays of Global Positioning System (GPS) receivers and strainmeters which will be used to deduce the strain field on timescales of days to decades. MPBO Overview...
Parkfield High-Resolution Seismic NetworkLocated in Parkfield, California, the HRSN is a small network of closely spaced 3-component borehole sensors. HRSN Overview
Bay Area Regional Deformation Network
BARD is a network of 32 continuously operating Global Positioning System receivers in Northern California. The primary goal of the network is to monitor crustal deformation across the Pacific-North America plate boundary and in the San Francisco Bay Area for earthquake hazard reduction studies and rapid earthquake emergency response assessment. BARD Overview...
