This paper aims to highlight the use of the georadar as a useful prospecting
technique to identify the areal density and the geometrical features of the
grottoes placed in a historical town characterised by high seismic hazard.
The town considered here is Rionero in Vulture (Southern Italy) that was hit
by several historical earthquakes, among which the 1930 Irpinia earthquake
(Me=6.7, Is=VIII MCS).
For this event a damage map was already available from a previous study
(Gizzi and Masini, 2006). This map shows that some sectors of the town
suffered higher damage. One factor causing the uneven distribution of the
effects is considered to be the presence of grottoes.
To strengthen this work hypothesis it was necessary to in-depth investigate
the subsoil of Rionero in Vulture. Therefore, geophysical data were
correlated and integrated with data obtained from field surveys and
historical documentary sources. All these investigations allowed to obtain
more insights about the influences of the man-made caves on seismic damage. |
