Abstract

The evaluation of local site effects, by means of ground response analyses, is a very complex and difficult task, which requires a multidisciplinary approach. This is operative philosophy expressed by VEL Project (Valutazione degli Effetti Locali), sponsored by Tuscany Region, to the aim to seismic risk characterization in the main seismic areas (i.e. Garfagnana, Lunigiana, Amiata, Valtiberina and Mugello). One of the most important urban centres, involved in the multidisciplinary activity of the VEL project, is certainly the town of Fivizzano located nearby the city of Massa, which was strongly damaged during the earthquake of September 1920 (the strongest seismic event occurred in Northern Apennines in the latest centuries). Remarkably good macroseismic information is available about the destructive impact yielded at Fivizzano by this earthquake (e.g. number of casualties, level of damage of buildings, etc). The main objective of this paper is to identify the occurrence of possible local site effects in the Fivizzano’s area following the 1920 earthquake and to quantify them by means of one and two-dimensional site response analysis. The input data required for study were obtained through a comprehensive geological survey and a multi disciplinary underground exploration of the area.

Problems Associated With the Assessment of Local Site Effects Through a Multidisciplinary Integrated Study: The Case of Fivizzano’s Town (Italy)

New York, New York

The evaluation of local site effects, by means of ground response analyses, is a very complex and difficult task, which requires a multidisciplinary approach. This is operative philosophy expressed by VEL Project (Valutazione degli Effetti Locali), sponsored by Tuscany Region, to the aim to seismic risk characterization in the main seismic areas (i.e. Garfagnana, Lunigiana, Amiata, Valtiberina and Mugello). One of the most important urban centres, involved in the multidisciplinary activity of the VEL project, is certainly the town of Fivizzano located nearby the city of Massa, which was strongly damaged during the earthquake of September 1920 (the strongest seismic event occurred in Northern Apennines in the latest centuries). Remarkably good macroseismic information is available about the destructive impact yielded at Fivizzano by this earthquake (e.g. number of casualties, level of damage of buildings, etc). The main objective of this paper is to identify the occurrence of possible local site effects in the Fivizzano’s area following the 1920 earthquake and to quantify them by means of one and two-dimensional site response analysis.
