Abstract
The Italian peninsula is the focus of intense deformational tectonic activity. It is underlain by mantle material whose inferred, relatively anomalous properties1,2 are not inconsistent with the seismic, volcanic and thermal activity that is manifested in this region. The most effective geophysical tool for mapping the structure of the uppermost 200–300 km of the Earth is the observation and analysis of seismic surface-wave dispersion on a regional scale. Here we synthesize the interpretations of Rayleigh wave dispersion measurements made by several authors, each for different parts of North Central Italy3–8, to delineate the lateral extent of the upper mantle anomaly in this region.
