GNGTS 2014 S essione 2.2 127 Conclusions. The huge concentration of earthquake damages within the southern edge of L’Aquila terrace and the complex local subsoil conditions (soft soil overlaying stiff basement; fine-grained soils interposed within, or placed above, the coarse-grained breccias known as “red soils”; man-made fills; underground caves; topographic effect) focused to deeply study this area for its restoration�. In particular, the combination of the available geological, geophysical and geotechnical data carried out for the restoration and the redevelopment with the noise measurements contributed to detect the ����� ������� ���������� �� ��� �������� ���� �� ��������� �� ���������� local subsoil conditions of the southern part of L’Aquila. In particular information on the highly variable thickness of the red soils were estimated through the high- resonance frequency f 1 , and considerations on the possible influence of a topographic effect were introduced through ��� ������������� ��������� the low-��������� ��������� resonance frequency f 0 , in terms of frequency, amplitude and shape of the H/V curves. Further studies are necessary to validate these preliminary results, considering in detail the available data along Porta di Bagno and Porta Napoli trenches, and Collemaggio scarp, and performing additional measurements along the other scarps that border L’Aquila terrace ����� (e.g. Porta Rivera and Collemaggio trenches).
