This map shows, in purple and pink, the west-east line of magnetotelluric sensors that were placed north of Washington state’s Mount Rainier to study the volcanic plumbing system under the volcano. The sensors detect how the ground resists or conducts natural electricity within the Earth. Shown in yellow are seismic sensors that detect how fast or slow sound or seismic waves travel underground. Both methods were used in a new study that provides the most detailed look yet at the subterranean plumbing system that supplies the active volcano.
