The paper presents a case study of CPT—based liquefaction assessment and mapping, carried out in an area of the north eastern Italian coast.

The zone lies on a nearly flat plain between the Adriatic Sea and the Apennines, and is of special interest from an economic and historical point of view. In the past, several seismic events with intensities over VIII  MCS struck many cities and urban settlements on the coast, producing severe damage to buildings and monuments. This damage was well described in detail by coeval chronicles and documents; several phenomena observed by eyewitnesses in the proximity of the beach appeared attributable to liquefaction occurrences. Thus, a public project for liquefaction hazard assessment and zonation was funded by the Emilia-Romagna Regional Government in the framework of a broader Microzonation Project. More than 1000 CPT profiles were collected, digitised and utilised for evaluating liquefaction hazard by means of the Robinson and

Warm simplified method [1997b].

The mapping methodology was based on the use of the potential liquefaction index, which has

been utilised as an integral parameter for comparing the liquefaction hazard ofthe various explored verticals and for drawing up liquefaction potential maps.

The criteria adopted aud the results of CPT-based liquefaction hazard zonation are presented and discussed.
