The Relationship between Damage and Peak Accelerations in Ripabottoni during the 2002 Molise, Italy, Earthquake Available to Purchase

After the main shocks of the 2002 Molise, Italy, earthquake sequence, the University of Genoa Geophysical Section (Dip. Te. Ris) installed a temporary seismic network, composed of two velocimetric and two accelerometric stations, in the village of Ripabottoni (Campobasso Province), near the epicentral area. These stations were implemented in the regional network of seismic instruments installed after November 1 by geophysical institutes from Rome and Trieste, Italy. The network registered more than 2,000 aftershocks with magnitudes ranging from 1.0–4.0. A DISEG Group also participated in a survey coordinated by the Larino Emergency Operations Center to examine damaged churches. The preliminary data, which correlates the waveform of the available recordings from aftershocks with damaged masonry pillars, indicates that the damage may relate not only to the intrinsic vulnerability of this building type, but also to the high energy in the high frequency range observed in the vertical component of the earthquakes.
