  11. Understanding Animal Detection of Precursor Earthquake Sounds

    Contributor(s): Michael Garstang, Michael C. Kelley

    We use recent research to provide an explanation of how animals might detect earthquakes before they occur. While the intrinsic value of such warnings is immense, we show that the complexity of the process may result in inconsistent responses of animals to the possible precursor signal. Using...
