| Summary: | This work shows the result of an
electrical resistivity tomography (ERT) survey carried out for imaging and
characterizing the shallow subsurface affected by the coseismic effects of
the Mw = 6.1 Emilia-Romagna (northern Italy) earthquake that occurred on
20 May 2012. The most characteristic coseismic effects were ground failure,
lateral spreading and liquefaction that occurred extensively along the
paleo-Reno River in the urban areas of San Carlo and Mirabello (southwestern
portion of Ferrara Province). In total, six electrical resistivity
tomographies were performed and calibrated with surface geological surveys,
exploratory boreholes and aerial photo interpretations. This was one of first
applications of the electrical resistivity tomography method in investigating
coseismic liquefaction. |
