THE RESOLUTION OF GEOLOGICAL ANALYSIS AND MODELS FOR EARTHQUAKE FAULTING STUDIES
No full textThe workshop was jointly organised by the Geo-Structural and Tectonic Studies Group (GST) of the University of Camerino, as a contribution to the research Project “Neotectonics and active tectonics in Apennines“ co-funded by MURST (Ministero dell’Università e della Ricerca Scientifica e Tecnologica), and by the Italian Agency for Environmental Protection (ANPA).
The aim of the workshop, attended by about 90 researchers from many different countries (Australia, France, Italy, Japan, New Zealand, Russia, USA), was that of providing a forum for specialists of various disciplines in order to discuss the different aspects of earthquake geology and their bearing on seismic hazard analysis. The in-door session of the meeting was preceded by a two-day field trip in central Italy, where surface faulting effects associated with damaging earthquakes (Norcia-L’Aquila, 1703, M=7.0; Fucino, 1915, M=7.0; Norcia, 1979, M=5.9; Colfiorito, 1997, M=6.0) are clearly recorded within both the carbonate basement units of the Apennines and the Quaternary continental deposits filling the intramontane basins of the apenninic mountain range.
The workshop was convened by E. Tondi (GST) and A.M. Michetti (ANPA) and was supported by an organizing committee (G. Cello and G. Deiana for the GST, and L. Serva and E. Vittori for the ANPA). The secretarial work was carried out mostly by C. Invernizzi and L. Marchegiani (GST), with the help of graduate and post-graduate students of the Earth Science Department of Camerino University
Future trends in paleoseismology: Integrated study of the seismic landscape as a vital tool in seismic hazard analyses
No full textThis paper forms the Introduction to this Special Issue of Tectonophysics, devoted to selected scientific research
presented during events sponsored by the INQUA Subcommission on Paleoseismicity in the past few years. In this
note, we summarize the contents of the contributed papers and use the issues they raise to review the state-of-the-art in
paleoseismology from a Quaternary geology perspective. In our opinion, the evolution of paleoseismological studies in
the past decade clearly demonstrates that in order to properly understand the seismic potential of a region, and to
assess the associated hazards, broad-based/multidisciplinary studies are necessary to take full advantage from the
geological evidence of past earthquakes. A major challenge in future paleoseismic research is to build detailed
empirical relations between various categories of coseismic effects in the natural environment and earthquake magnitude/
intensity. These relations should be compiled in a way that is fully representative of the wide variety of natural
environments on Earth, in terms of climatic settings, Quaternary tectonic evolution, rheological parameters of the
seismogenic crust, and stress environment. For instance, available data indicate that between earthquake magnitude and
surface faulting parameters different scaling laws exist, and they are a function of the local geodynamic setting
(including style of faulting, typical focal depths, heat flow). In this regard, we discuss in some detail the concept of
seismic landscape, which provides the necessary background for developing paleoseismological research strategies. The
large amount of paleoseismological data collected in recent years shows that each earthquake source creates a signature
on the geology and the geomorphology of an area that is unequivocally related with the order of magnitude of its
earthquake potential. This signature is defined as the seismic landscape of the area (e.g., Serva, L., Vittori, E., Ferreli,

the seismic behavior of faults capable of producing surface faulting and provides a comprehensive approach for the use of
paleoseismicity data in earthquake hazard characterization

EEE Catalogue: A Global Database of Earthquake Environmental Effects
No full textThe recent destructive earthquakes that occurred in Japan (2011; e.g., Lay et al. 2013) and New Zealand (2010–2011 earthquake sequence; e.g., Quigley et al. 2012) have clearly pointed out that traditional seismic hazard assessment based only on vibratory ground motion data needs to be integrated with information about the local vulnerability of the territory to earthquake occurrence. Nowadays, a huge amount of information about the characteristics of Earthquake Environmental Effects (EEEs; i.e., any phenomena generated by a seismic event in the natural environment; Michetti et al. 2004, 2007; Guerrieri et al. 2007) is available for a very large number of earthquakes that occurred not only in the instrumental period and in historical time but also in the prehistorical period (paleoearthquakes, e.g., Mc Calpin 2009; Reicherter et al. 2009)

The Dead Sea Rift as a natural laboratory for earthquake behavior: prehistorical, historical and recent seismicity
No full textThe DSW 2009 - Field Trip & Workshop "The Dead Sea Rift as natural laboratory for earthquake behaviour: prehistorical, historical and recent seismicity", held in Israel on 16th-23rd February, 2009, was organized by the Geological Survey of Israel and INQUA Focus Group on Paleoseismology and Active Tectonics, in collaboration with UNESCO (IGCP project 567 “Earthquake Archaeology”).
This event was aimed at improving our understanding of Paleoseismology and Seismic Hazard Assessment, at a global level and specifically in the Eastern Mediterranean Region, with an emphasis on the study of the environmental effects of earthquakes and on the application of the ESI 2007 intensity scale. The region of the Dead Sea Rift is in fact the object of large engineering projects, such as the Dead Sea - Red Sea water conduit project, and existing and planned nuclear facilities in Israel and Jordan.
A six days long field trip along the Dead Sea fault from Hula Valley at the border with Lebanon, to the Red Sea and Aqaba in Jordan, was organized by the Geological Survey of Israel in collaboration with the Hebrew University of Jerusalem, Tel Aviv University and Ben- Gurion University, Beer Sheva, Israel. This volume is the comprehensive Field Trip Guide for the DSW 2009. The field trip spanned 4 seasons, from the snowy Mt Hermon, to the rainy Sea of Galilee region, and to the hot arid desert -- Dead Sea, Arava valley and to the Red Sea, the Aqaba/Eilat area, allowing to examine a wide variety of climatic and geomorphic settings. The “fil rouge” of the trip was of course the trace of the Dead Sea Tranform, which was followed for more than 300 km, with about 35 stops. The participants examined unique field exposures presented by expertise of each site and discussed, among others, A) seismically-induced landslide hazards near the Sea of Galilee and South of the Dead Sea, B) evidence of archaeoseismicity at a variety of location along the Jordan River Valley, Dead Sea Rift and at Aqaba/Petra, C) paleoseismic surface faulting exposed along trench walls in the Arava Valley, and damaged and offsett archaeological remains at Qala'at Al-Subeiba Namrod fortress, Vadum Jacob, Susita, Petra, and Ayla (Aqaba) in Jordan:, D) paleoliquefaction features preserved in the Lisan Formation around the Dead Sea, E) long paleoseismic record from deformed speleothemes in the Soreq Cave near Jerusalem
