Teleseismic P waves recorded by a short-period seismic network, comprising 12 stations, in Yellowstone National Park, show anomalous delays of 1-2 s in their travel times in the central region of the park relative to the surrounding area. To explain this phenomenon, the author proposes that a substantial body of low velocity material is present beneath the park, with horizontal dimensions of several tens of kilometers: it may be the magma chamber associated with the volcanism of Yellowstone.
