Two Natural Hazards - Comparing the risk management of quick clays and unstable rock formations in Norway

Abstract

The geological basis of these hazards governs the necessity of differences in the approach to controlling risk and preventing major consequences that could claim many lives. These differences are most apparent when looking at the individual factors that determine the risk of each hazard and are well illustrated in the comparative analysis of the two cases chosen in the thesis. These differences in approaches also cause different outcomes for the inhabitants of each case region. The challenges faced by attempting to control the two hazards are different and generally more severe in the case of quick clay mostly due to a more diverse range of actors involved in directly controlling the hazard. The final risk picture formed from attempting to control each of the case hazards is quite similar, but the differences lie in the character of each hazard and the way they are managed.
