Hazard and risk assessment of sinkholes

Part of the Karst and Cavernous Rocks in Engineering and Const book series (PRAXIS)

Abstract

Where a hazard impinges upon human activity, it involves a degree of risk, the elements at risk being life, property and possessions; the natural environment may also be affected, though this may be considered as part of natural change. Risk involves quantification of the probability that a hazard will be harmful, and the tolerable degree of risk depends upon what is being risked, life being more important than property. The frequency of a particular hazard event can be regarded as the number of events of a given magnitude in a particular period of time at a certain location. As such, a recurrence interval for such an event sometimes can be determined in terms of the average length of time between events of a certain size. The risk to society can be regarded as the magnitude of a hazard multiplied by the probability of its occurrence and by the cost of its impact. If there are no hazard mitigation measures for an area that is subjected to a recurring hazard, then such an area has the highest vulnerability.
