For each area a dataset of about fifteen earthquakes of the 20th century, selected to cover the largest magnitude range, was compiled according to homogeneous procedures. The Boxer and Meep methods are accompanied by codes which provide calibrated coefficients from the input dataset. The Bakun & Wentworth method requires an intensity attenuation relation as function of the moment magnitude and hypocentral distance.

  • Il Terremoto Irpino Del 1930: Caratteristiche Della Sorgente Sismica Da Simulazioni Numeriche Del Processo Di Frattura

Zollo (1) (1) Dipartimento di Scienze Fisiche, Università degli Studi “Federico II”, Napoli (2) Servizio Sismico Nazionale, Roma (3) Osservatorio Vesuviano, Napoli IL TERREMOTO IRPINO DEL 1930: CARATTERISTICHE DELLA SORGENTE SISMICA DA SIMULAZIONI NUMERICHE DEL PROCESSO DI FRATTURA Riassunto. In questo lavoro sono rivisitate le caratteristiche di sorgente del terremoto irpino del 23 luglio1930 (IMAX=X) utilizzando la metodologia proposta da Zollo et al. (1997) per simulare le accelerazioni del moto. Le stime dell’accelerazione teorica ottenute dalle simulazioni numeriche sono state poi convertite in valori di intensità macrosismica mediante la relazione di Trifunac e Brady (1975) e confrontate (entro l’incertezza di una deviazione standard) con i valori disponibili da catalogo (Camassi e Stucchi, 1998). I risultati delle simulazioni mostrano che una faglia di dimensioni 25×12 km2, caratterizzata da un meccanismo normale, orientata in direzione appenninica e immergente di un angolo pari a 55° in direzione SW e con momento sismico di 5.6×1025 dyne⋅cm sembra ben riprodurre l’estensione areale del campo di intensità macrosismica. Tale faglia deve infine essere traslata di circa 10 km verso SW rispetto alle localizzazioni del terremoto irpino del 1930 note dalla letteratura al fine di rendere minimo lo scarto tra i valori di intensità macrosismica disponibili da catalogo e quelli calcolati in base ai valori di accelerazione simulati negli stessi punti.

We have merged the historical record and the new satellite techniques that allow a precise determination of ground movements, and then derived physical dimensions like strain rate. In this way, we have verified that in Irpinia the hazard of new strong shocks forty years after one of the strongest known seismic events in the district is still high. This aspect must be considered very important from many points of view, particularly for Civil Protection plans, as well as civil engineering and urban planning development. 1. TECTONICS AND GROUND MOTION IN SOUTHERN APENNINES The study is based on the analysis of a fine-scale ground velocity map of Italy determined by the fusion of Global Navigation Satellite Systems (GNSS) with the synthetic aperture radar interferometry (InSAR) derived from satellite [1]. The datasets cover a period of observation of twenty years, between 1991 and 2011. The InSAR dataset is part of the “Piano Straordinario di Telerilevamento” (Special program for Remote Sensing, promoted by the Italian Ministry of Environment).

This Input motion selection requires an accurate geotechnical characterisation of the dam and foundation soils, a proper definition of the Displacement analyses seismic scenarios at the site of the dam, the use of simplifiedprocedures for screening-level seismic analyses and Shear strength reduction advanced non-linear dynamic analyses to study the most critical seismic scenarios. This process has been used for the evaluation of the seismic performance of a zoned earth dam located in a high seismic hazard area of Southern Italy. In this paper the available data of historical seismicity at the site of the dam and the results of a probabilistic seismic hazard analysis are first discussed and input ground motions are selected using compatibility criteria with the energy and frequency content of the expected target motion in a range of vibration period relevant for the non-linear response of the dam.

  • The Environmental Effects of the 1743 Salento Earthquake (Apulia, Southern Italy): a Contribution to Seismic Hazard Assessment of the Salento Peninsula
    Nat Hazards DOI 10.1007/s11069-016-2548-x ORIGINAL PAPER The environmental effects of the 1743 Salento earthquake (Apulia, southern Italy): a contribution to seismic hazard assessment of the Salento Peninsula 1 1 1 1 R. Nappi • G. Gaudiosi • G. Alessio • M. De Lucia • S. Porfido2 Received: 22 December 2015 / Accepted: 19 August 2016 Ó The Author(s) 2016. This article is published with open access at Springerlink.com Abstract The aim of this study was to provide a contribution to seismic hazard assessment of the Salento Peninsula (Apulia, southern Italy). It is well known that this area was struck by the February 20, 1743, earthquake (I0 = IX and Mw = 7.1), the strongest seismic event of Salento, that caused the most severe damage in the towns of Nardo` (Lecce) and Francavilla Fontana (Brindisi), in the Ionian Islands (Greece) and in the western coast of Albania. It was also widely felt in the western coast of Greece, in Malta Islands, in southern Italy and in some localities of central and northern Italy. Moreover, the area of the Salento Peninsula has also been hit by several low-energy and a few high-energy earth- quakes over the last centuries; the instrumental recent seismicity is mainly concentrated in the western sector of the peninsula and in the Otranto Channel. The Salento area has also experienced destructive seismicity of neighboring regions in Italy (the Gargano Promon- tory in northern Apulia, the Southern Apennines chain, the Calabrian Arc) and in the Balkan Peninsula (Greece and Albania). Accordingly, a critical analysis of several docu- mentary and historical sources, as well as of the geologic–geomorphologic ground effects due to the strong 1743 Salento earthquake, has been carried out by the authors in this paper; the final purpose has been to re-evaluate the 1743 MCS macroseismic intensities and to provide a list of newly classified localities according to the ESI-07 scale on the base of recognized Earthquake Environmental Effects.

The main objective of the project is to improve the understanding of earthquake generation processes in Italy and to characterize the earthquake source and medium properties in the three selected test sites by developing and applying innovative methodologies aimed at the massive processing, analysis and modelling of multi-parametric geophysical data available in real-time and off-line data banks. According to the original workplan the research activities of project S5 during the first year concerned 1/ the development of methods for seismic and geodetic data analysis in continuous and off-line modes, code implementation and testing on real and synthetic data: 2/ the collection, formatting and archiving of seismic and GPS data from test-site areas and their publication on web-accessible relational data-bases 3/ collection, analysis and interpretation of geological data on the ATF fault and 4/ the instrument deployment, in particular the sea- bottom array of seismographs installed off-shore of Sicily.
