Approaches to Industrial Risk Assessment Coupled with Catastrophic Natural Phenomena

The aim of this contribution is to focus attention on a new emerging risk known in the literature as Na-Tech risk (Natural-Technological risk). Na-Tech are technological accidents triggered by natural events, these are of particular interest for high risk industries. The magnitude of such an event is much broader than that related to a technological accident and its management is much more complex. Adequate preparedness, proper emergency planning and effective response are crucial for the prevention and mitigation of the consequences of Na-Techs This contribution gives a general overview of the methodologies, that are currently being developed, in order to integrate these types of scenarios into the conventional quantitative risk analysis for chemical and process industry.
