- ItemA Statistical Model for Earthquake And/Or Rainfall Triggered Landslides(Frontiers Media S.A., 2021-02-04) Frigerio Porta G; Bebbington M; Xiao X; Jones G; Xu CNatural hazards can be initiated by different types of triggering events. For landslides, the triggering events are predominantly earthquakes and rainfall. However, risk analysis commonly focuses on a single mechanism, without considering possible interactions between the primary triggering events. Spatial modeling of landslide susceptibility (suppressing temporal dependence), or tailoring models to specific areas and events are not sufficient to understand the risk produced by interacting causes. More elaborate models with interactions, capable of capturing direct or indirect triggering of secondary hazards, are required. By discretising space, we create a daily-spatio-temporal hazard model to evaluate the relative and combined effects on landslide triggering due to earthquakes and rainfall. A case study on the Italian region of Emilia-Romagna is presented, which suggests these triggering effects are best modeled as additive. This paper demonstrates how point processes can be used to model the triggering influence of multiple factors in a large real dataset collected from various sources.
- ItemSmall-area Estimation of Poverty and Malnutrition in Cambodia.(National Institute of Statistics, Ministry of Planning, Royal Government of Cambodia and the United Nations World Food Programme, 2013-04) Haslett SJ; Jones G; Sefton AThe Small-Area Estimation of Poverty and Malnutrition in Cambodia report is a joint effort between the National Institute of Statistics of the Ministry of Planning of the Royal Government of Cambodia, the United Nations World Food Programme Cambodia, and Massey University, New Zealand. The report contains commune-level estimates of poverty (incidence, gap and severity) and malnutrition (stunting and underweight), and corresponding GIS maps, for Cambodia. The report includes detailed statistical analysis of the Cambodia Socio-Economic Survey 2009, the General Population Census 2008, the Cambodia Demographic and Health Survey 2010 and the Cambodia Anthropometric Survey 2008.
