b'The Presidents CommentaryPredicting Volcanic EruptionsHere on Earth, National Science Foundation postdoctoral fellow Kathleen McKee joined staff scientists Diana Roman, Hlne Le Mvel, and other collaborators to establish the first-ever quantitative link between the subsurface gas movements that occur before eruptions and the ensuing explosion. Their research on Stromboli Volcano combined the use of 10 infrasound sensors with one of the first deployments of Carnegies Quick Deploy Boxes (QDBs), compact and cost-effective broadband seismometers developed by the Department of Terrestrial Magnetism. Through their measurements of Stromboli Volcanos shallow plumbing system, the researchers were able to quantify the flow rate of simple explosionsan important step toward their goal of reducing threats to communities near active volcanoes. Carnegie researchers work in the field and lab to understand many aspects about the Earth. A Carnegie team, with colleagues, conducted experiments with a variety of instruments at Stromboli Volcano, Italy, (shown) to investigate how seismic signals from subsurface gas movement and acoustic signals from explosions are linked.
