New acoustic early warning system for landslides developed

People living in landslide-prone areas will be glad to know that a new technology has been developed which monitors soil acoustics to determine when a landslide is imminent. The system consists of a network of sensors, buried across a hillside considered a risk. As soil moves within the hillside, it creates noise – the more the amount of movement, the louder the noise. When that noise reaches a threshold level, the system sends a text message warning to local authorities, that a landslide is about to occur.
