Abstract

Mt. Vesuvius is a small volcano associated with an elevated risk. Seismic data 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-kilometer depth. The inferred S -wave (∼0.6 to 1.0 kilometer per second) and P -wave velocities (∼2.0 kilometer per second) as well as other evidence indicate an extended sill with magma interspersed in a solid matrix.
