Description:
The Larderello-Travale Geothermal Field in South-West Tuscany (Italy) is the oldest and among the most pro-
ductive geothermal fields in the world. A new 3D model of seismic P-wave velocity (V P ) of the upper crust
beneath the geothermal field is derived by inverting a set of highly consistent travel-times from local-earth-
quakes. Results document a marked correlation of V P with previously described, high-reflectivity horizons. We
also determined a low velocity body (V P ∼5 km s −1 ) culminating at depths of about 7 km, with estimated vo-
lume of 35–40 km 3 . Such low velocities are consistent with a granite at temperatures above 700 °C, thus in a
partially-molten status.
