Quantitatively analysing holistic risk and testing the accident coping strategies

Abstract

Climate change hazards and malicious attack threats are major problems that the world must start to mitigate, prepare for, cope with and adapt to. A more holistic approach to severe event-hazard/threat risk assessment thereby accounts for the infrastructure’s damage, the scale and capability of preparedness, the success of response and final recovery actions, investigating the complete coping cycle for the particular socio-technical system of interest. A holistically based coping test method has been developed by Arup, called the “Holistic Integrity Test” (HIT). In broad terms for application, there are 10 key risk-related socio-technical system integrity factors that will advise governing authorities of their region’s coping capability against natural geo-hazards, including the effects of climate change, but also malicious attack threats.
