Abstract

<p><em>We used the moderate-magnitude aftershocks succeeding to the 2016 August 24<sup>th</sup>, Mw = 6.0, Amatrice (Italy) mainshok to asses, specially during an ongoing seismic sequence, the soil-structure interaction where cultural Heritage is involved. We have chosen as case study the</em><em> San Giovanni Battista</em><em> church (A.D. 1039) in Acquasanta Terme town, about 20 Km northeast of Amatrice. First of all we studied the soil shaking features in order to characterize the input to the monument. Then, using the recordings in the church, we tried to figure out how the input seismic energy is distributed over the different monument parts. Some preliminary results are shown and discussed.</em></p><p><em><br /></em></p>

Summary

INTRODUCTION

During the moderate magnitude aftershocks following the Amatrice earthquake (Mw=6.0) occurred on August 24, 2016 we installed eight portable seismic stations in the Acquasanta Terme town, located at about 20 km northeast of the mainshock zone (cf. Fig. 1a). The aim is to study the interaction between the incoming seismic wave-field and the San Giovanni Battista Church (A.D. 1039), a relevant cultural heritage in the town Such seismic sequence, offers a singular opportunity to calibrate the monument response to Central Apennines earthquakes, which have been responsible for the largest damage to the cultural. The locations of these stations were chosen in order to study mainly the interaction between the bell tower and the rest of the church structure. The repetition of the surveys during and after the seismic sequence allow an evaluation of the changes produced (cf. [Teza et al, 2015])
