The article reports on the installation of 15 robots in and around Mount Saint Helens in Washington by the U.S. National Aeronautics and Space Administration (NASA). The robots have been equipped with special instruments to measure ground changes and magma movements to warn scientists of a possible volcanic eruption. According to scientist Steve Chien, the robots' sensors detect the motions of magma, which is underground liquid rock that gets pushed up and out of a volcano during an eruption.
