Demo abstract, the next big one: Detecting earthquakes and other rare events from community-based sensors

Abstract

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 system using Android cell phones and a cloud fusion center that allows participants to create "mock earthquakes". Upon detecting such an event, the cloud fusion center issues real-time alerts to the phones. A map-based interface to the fusion center is projected nearby, displaying the information reported by the phones.
