Can inexpensive accelerometers, such as those in cell phones and other commodity devices, be used for earthquake detection and monitoring? Detecting rare, disruptive events using community-held sensors is a promising opportunity, but also presents difficult challenges. Rare events are often difficult or impossible to model and characterize a priori, yet we wish to maximize detection performance. Further,...
Can cell phones be used to detect earthquakes? The Community Seismic Network (CSN) is building a dense sensor network from inexpensive and community owned sensors, such as cell phones and USB accelerometers. Detecting rare events such as earthquakes is a difficult sensing problem, and is compounded by the wide variations among sensors in a heterogeneous community network. We demonstrate an end-to-end...
