Seismic/GPS station YOCR, at Mount Hood

Detailed Description

A Cascades Volcano Observatory field team completes the installation of the combined seismic/GPS station YOCR, at Mount Hood. Effective monitoring requires a geographically distributed network of instruments that are located on the upper flanks, and around the volcano, and for these stations to be in place before significant unrest occurs to catch the earliest subtle signals of rising magma.
