- Abstract
- The microzonation concerns the identification and mapping at local or site scales of areas having
different potentials for hazardous earthquake effects, such as groundshaking intensity, liquefaction, or landslide potential. In
order to obtain results for microzonation purpose it is necessary to record and to analyse the whole data set that derive from the
site analysis. The traditional approach to microzonation, only based on geological and geophysical surveys, allows to select
those urban sub-areas where potential high levels of damage may occur as a consequence of an earthquake. In contrast, the
synergistic use of seismic data gathered from the analysis of the building damage due to more earthquakes enables us to identify
the urban areas where relatively high levels of damage have already occurred in previous earthquakes. Starting from these point
of view, a multidisciplinary and integrated approach has been applied to Potenza, the chief-town of Basilicata region (southern
Italy), located in the axial zone of the southern Apennines, characterized by high seismic hazard. In fact, during about last two
centuries this town has been damaged by several earthquakes some of which characterized by high magnitude and intensity
(1694 Irpinia-Basilicata region Me= 6.8, Is=VIII MCS; 1857 Basilicata Me=7.0, Is=VIII-IX MCS; 1826 Basilicata Me=5.9,
Is=VIII MCS; 1930 Irpinia Me=6.7, Is=VI-VII MCS; 1980 Irpinia-Basilicata Me=6.7, Is=VII MCS). In order to microzone the
Potenza urban area, geological (field survey, drillings, stratigraphic sections), geotechnical (laboratory and site analysis),
geophysical (downholes and seismic refraction measurements) and three historical seismic damage 'scenarios' (derived by the
analysis of historical sources) have been implemented in a geodatabase on a GIS platform (ArcInfo) using the spatial analysis
functions. This approach permitted to get thematic maps which could be interpreted in perspective of a microzonation also
according to the recent seismic Italian law (PCM n 3274 23/3/2003). Finally, it must be emphasised that the geodatabase is
constantly and quickly up-to-date with regard to the latest investigations about the site and, therefore, new elaborations for
microzonation applications can be obtained as a consequence of new knowledges. (literal)
