Description:
We study five high precision leveling lines located around the epicentral area of 13 January 1915, Mw = 6.7 Fucino earthquake (Italy), that possibly recorded late stage
postseismic relaxation movements. The geodetic signal is expected to comprise both large-scale uplift of the Apennines and postseismic relaxation effects. In order to
verify this hypothesis and to estimate the amount of each contribution, we compute gravitational visco-elastic postseismic relaxation by inverting leveling data. Results indicate that the elastic upper crust is relatively thin (about 10 km) and post-seismic contribution could be set at 30% of the geodetic signal. Model parameters are consistent with previous knowledge of the 1915 Fucino earthquake source, local seismic hypocentral determinations and crustal models derived from surface waves.
