Aim of the project was to produce good practices for the study of seismicity and tsunamis potentially triggered by oil&gas production through the analysis of Crotone offshore case study (South Italy – Ionian Sea). After the 2012 Emilia earthquake, the ICHESE Commission (2014), stated that: “Triggered and induced seismicity is a rapidly developing area of study but the present state of knowledge, and in particular a lack of experience in Italy, does not currently allow the identification of protocols of actions which can be immediately used for practical purposes for seismic risk management. The first need is the development of know-how through acquisition of detailed data, some of which must be provided by operators, and research which can improve the knowledge of the relationships between technological operations and triggered seismicity. The seismicity and operational parameters should be closely inspected, and it is essential to have more than one case in order to be able to derive useful tools such as a traffic-light system. New hydrocarbon/geothermal exploration activities must be preceded by preliminary desk study and field-based screening evaluation based on an extensive and detailed 3-D geophysical and geological study, allowing the determination of the main fault systems which can be suspected to be active and their seismogenic characteristics (fault length, occurrence rate, etc.)”.
