SGER: A Wireless Sensor Network for Monitoring Volcanic Eruptions

点击翻译按钮获取中文摘要

This SGER proposal is aimed at developing a wireless sensor network, consisting of both acoustic and seismic sensors, for monitoring eruptions of active and hazardous volcanoes. We intend to develop and deploy a wireless sensor array at Volc'an Tungurahua, an active volcano in central Ecuador, in July-August 2005. Wireless sensor networks have the potential to greatly enhance our understanding of volcanic activity.This project will develop new wireless technologies for monitoring volcanic activity, which will lead to a richer scientific understanding of volcanic processes. The proposed large-aperture seismoacoustic sensor array will be deployed on the upper flanks of Tungurahua volcano, in an area that would otherwise not be readily accessible for multi-station data acquisition. The improved station coverage is in a critical (near-field) zone of the volcano and will enable much improved determination of source locations and mechanisms for explosions and other earthquakes in the shallow subsurface and volcanic conduit.
