Insights into bedrock paleomorphology and linear dynamic soil properties of the Cassino intermontane basin (Central Italy)

摘要: Abstract Seismic amplifications are dictated by the depth of bedrock and stratigraphy dynamic properties soil deposits. Quantifying these properties, together with their uncertainty, is a necessary task to perform reliable assessment seismic risk at an urban scale. In this paper, multidisciplinary analysis presented, where information different nature combined. Borehole logs, geophysical, geological geotechnical surveys interpreted aid analytical, numerical geostatistical techniques characterise complex shape linear sedimentary deposits filling Cassino basin, Quaternary intermontane basin located in central Italy. The regional local hazard firstly identified that reveal active seismogenic fault capable producing earthquakes estimated magnitudes up 6.7–6.8. Boreholes reaching depths variable maximum 180 m microtremor measurements, revealing sharp impedance contrast transition between sedimentary/arenaceous soft infilling, combined identify These one key factors governing propagation ground level waves, represents first step for characterisation plain.
