It is envisaged that the discussion presented in this paper, and the literature gaps identified, will form a basis for future comprehensive and cohesive research on disaster waste management. In turn, research will lead to better preparedness and response to disaster waste management problems.
Earthquakes generate loss only when assets are near enough to be significantly shaken. When communities are highly insured, much of that loss transfers to the insurer. Many events in the 2010–2011 Canterbury Earthquake Sequence were sufficiently shallow and close to (or under) Christchurch to subject the city to very intense shaking (V: 1.7 g; H: 2.2 g). Shaking damage was extensive, exacerbated by the city's setting wherein the eastern suburbs were built on low-lying flatlands (formerly swamp) where liquefaction was widespread, and the southern suburbs, on the flanks of the now-dormant Lyttelton/Akaroa volcano, experienced boulder roll and landslide effects. There were 17 events in the sequence that resulted in insurance claims. The interval between damaging events was insufficient to enable the widespread damage to be assessed or repaired. Furthermore, the combination of tectonic subsidence and liquefaction ejectile lowered the land surface, creating unacceptable flood risk. This paper provides a snapshot of the most complicated insurance settlement program experienced anywhere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
