Abstract

<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>

Highlights

The real-time acquisition of seismic data allows to define quickly the location and focal parameters of an earthquake, through the inversion of the data recorded directly on the surface by a seismic network
The monitoring of strategic public buildings is important to check the status of the structures and collect instrumental seismic history and helps to evaluate the damage scenario following a destructive earthquake in the area
A monitoring approach is in testing phase, using a single accelerometer placed at the base of a structure with low-cost instrumentation, with the dual purpose of improving the estimates of shaking on the territory increasing the points at which accelerometer data are recorded and evaluating the potential damage of public buildings to contribute to the rapid response of civil protection

Summary

Introduction

The real-time acquisition of seismic data allows to define quickly the location and focal parameters of an earthquake, through the inversion of the data recorded directly on the surface by a seismic network. The damage of strategic public buildings aggravates the emergency situation resulting from a destructive seismic event.
