Community Information

<p>The Marche Region, in collaboration with INGV, has promoted a project to monitoring public strategic buildings with permanent accelerometer installed at the base of the structures. Public <ins cite="mailto:chiara" datetime="2016-09-27T12:50">structures</ins> play a primary role to maintain the functionality of a local community. Information about vibratory characteristics of the building and subsoil, in addition to the seismic instrumental history that describe the seismic shaking at the base of the structure are collected for each buildings. The real-time acquisition of seismic data allows to obtain accelerometric time history soon after the occurrence of an earthquake. The event of 24 August 2016 in Central Italy was an opportunity to test the functionality of this implemented system. In this work the parameters obtained from strong motion data recorded at the base of the structures were analyzed and the values obtained were inserted with some <ins cite="mailto:mnoise" datetime="2016-09-26T10:13">empirical relationships </ins>used to provide intensity microseismic values and damage indices.</p>

The Impact

An earthquake of estimated local magnitude (ML) 6.0 struck central Italy on the 24th of August (01:36:32 UTC) in the vicinity of Accumoli (close to Rieti, central Italy) initiating a long-lasting seismic sequence that also featured events of larger magnitude within a few months. The earthquake caused widespread building damage and around three-hundred fatalities. Ground motion was recorded by hundreds of seis-mic stations. This work uses accelerometric records for a preliminary discussion, from the earthquake en-gineering perspective, of strong motion caused by the earthquake. Peak and integral ground motion inten-sity measures, are presented. The response spectra at some select stations are analysed with respect to the code-mandated design actions for various return periods at the recording sites. Hazard disaggregation for different return periods is discussed referring to the site of the epicentre of the earthquake. Finally, some preliminary considerations are made concerning the impact of rupture propagation on near-source ground motion; i.e., the records are scanned for traces of pulse-like forward-directivity effects.

<p class="western" align="justify"><span style="font-family: 'Bitstream Charter', serif;"><span>By extending the conventional Beam-Forming frequency-wavenumber power spectral estimate to the case of arbitrarily-shaped wavefronts, we obtained images of rupture propagation during the 2016 August 24, Mw=6.0 central Italy earthquake. Using a set of strong-motion accelerometers, we evaluate the beam power along the travel time curves associated with synthetic sources spanning a model fault surface. This allows deriving time-dependent images of the distribution of energy radiation throughout the fault plane. Results indicate bi-lateral rupture propagation toward SE and NW, in rough agreement with surface co-seismic displacement and surface damage pattern. To a first order, our results are also consistent with those obtained from full-waveform inversion of strong-motion data.</span></span></p>
