Due to the increasing number of natural events, such as landslides, earthquakes and floods, industrial facilities are becoming more vulnerable to NaTech accidents (NAtural hazard triggering TECHnological disasters). Moreover, the NaTech accidents that have already occurred in natural gas industry are an unchallenged argument related to the necessity and importance of performing NaTech risk evaluation studies during industrial activities, but especially before their design. The aim of this paper is to underline the need of NaTech risk approach in natural gas industry, especially in extraction and transport activities. Hence, this paper is a review on both NaTech accidents that have already occurred in natural gas extraction and transmission pipelines, (taking into account landslides as the natural triggering event), as well as on the risk assessment methodologies already proposed in this field.
