Definition of the standard format to prepare descriptive monographs of ITACA stations

Progetto DPC-INGV S4 "Banca dati accelerometrica" - Task 2

In the previous S6 Project (2004-2007 DPC-INGV Framework Program) a monograph was carried out, that was drawn up for many stations, that were part of the former ENEL
accelerometric network. In these monographs all the ENEL documentation about geological
information as well as geognostic and geophysical data was included.
Knowledge of geological and geomorphological context, and the mechanical and dynamic
characteristics of the stations subsoil is fundamental for studies on the attenuation laws and
the selection of accelerograms to be used as a seismic input for dynamic analyses for which a
classification of the stations subsoil according to the EC8 and national code provisions is
necessary. Considering the huge number of sites (over 600), this knowledge have to be
rationalized and homogenized so as to arrive at a common and comparable level of
information.
The station monograph carried out within the past S6 INGV Project had tried to fill the gap in
the knowledge of the recording station characteristics, with the advantage of providing a first
screening on the quantity and quality of available data; however the collected data included in
the monograph turned out to be uneven and incomplete since a robust standard for the
collection, homogenization, representation and synthesis of data was not provided. Moreover,
expert judgment for assessing quality of data, especially those derived from geotechnical and
geophysical tests, was not taken into consideration.
This problem has been addressed by Task 2, which has produced a new standard monograph
for the ITACA stations. The new release of the station monograph is the first product of the
5
S4 Project (deliverable D3) and can be downloaded from the project website
(http://esse4.mi.ingv.it).
The new ITACA monograph provides a minimum level of information,
homogeneous for all station sites, including multi-disciplinary data to satisfy the needs of
different users and duly considers information previously not included.
In detail, the new ITACA monograph consists in the following 12 cognitive modules, and
various sub-modules.
