The massive research program EarthScope has been rolling along for the last eight years. Because its SAFOD component, which drilled a borehole across the San Andreas fault, was in my neighborhood I covered it here pretty thoroughly. Now an article in Earth magazine surveys the results of USArray, the project that has been assembling a detailed portrait of the U.S. portion of the North America plate using a "stethoscope" of hundreds of seismometers. It covers what we found when USArray examined the Yellowstone hotspotno surprise to me, the results have an explanation that does not require a mantle plume. It also zeroes in on three Midwest studies that are piggybacking on USArray, which promise significant advances in our dim picture of the deep crust there. USArray will soon be coming to the east coast states; keep your eyes open.
