How Do Consecutive Disasters Affect Damages and the Post-Disaster Recovery Process?
Abstract
The number of studies presenting theoretical frameworks to assess multi-risk is growing. While a large body of literature addresses multi-risk based on the spatial overlap between the exposure of different hazard types faced by one particular area, the temporal aspect of coincidental hazards has been studied to a much lesser extent. Yet, neglecting the residual risk from the impact of consecutive hazards can lead to a strong bias in the total risk.
Several of the existing studies have applied their theoretical framework to a case study (e.g. Marzocchi et al. 2012) to demonstrate its empirical implementation. However, the case studies used for the empirical application of their theoretical frameworks generally are conducted at a very small spatial scale (e.g. municipality or neighbourhoods) and a short temporal scale (e.g. a year). In this paper, we build upon and expand on the existing theoretical frameworks by conducting an empirical study of historic disaster and impact data of typhoons, earthquakes and volcanic eruptions in the Philippines from 1966 until 2016, where we assess consecutive risk at both different spatial and temporal scales. The selection of the time window reflects common insurance standards (the hours-clause) but also commonly used definitions of recovery in practice (i.e. 3, 30 and 180 days). Similarly, these interactions are analyzed at different relevant spatial scales (i.e. national, regional and municipality level).- Publication:
