Abstract
Mt. Vesuvius is a small volcano associated with an elevated risk. Seismic d ata were used to better define its magmatic system. We found evidence of an extended (at least 400 square kilometers) low-velocity layer at about 8-ki lometer depth. The inferred S-wave (similar to0.6 to 1.0 kilometer per seco nd) and P-wave velocities (similar to2.0 kilometer per second) as well as o ther evidence indicate an extended sill with magma interspersed in a solid matrix.
