Wireless seismic and volcanic monitoring in ecuador

Abstract:

Geophysicists at the Institute of Geophysics of Ecuador have implemented real-time monitoring systems using robust FreeWave's DGR Series radios coupled with a variety of sensors, for the country's volcanos and other seismically active areas, leading to improved knowledge and public safety. The radios transmit images from the top of Cotopaxi, the highest active volcano in the world, and operate at temperatures below 0°C and at a height of 5947 m above sea level. Each piece of equipment is connected to the institute's internal network, allowing researchers to access it from any part of the network. The radios have been used in conjunction with GPS receivers for deformation monitoring. Seismic broadband monitoring using the radios enable the institute to deliver early warning about the eruptions of the Tungurahua volcano in 2006 and in 2008.
