Monitoring Volcanic Eruptions With a Wireless Sensor Network
Overview This paper describes the experiences using a wireless sensor network to monitor volcanic eruptions with low-frequency acoustic sensors. The paper developed a wireless sensor array and deployed it in July 2004 at Volcan Tungurahua, an active volcano in central Ecuador. The network collected infrasonic (low-frequency acoustic) signals at 102 Hz, transmitting data over a 9 km wireless link to a remote base station. During the deployment, they collected over 54 hours of continuous data which included at least 9 large explosions. Nodes were time-synchronized using a separate GPS receiver, and the data was later correlated with that acquired at a nearby wired sensor array.
