You can help compile the NASA landslide catalogue<\/h4>\n

For the last few years Dalia Kirschbaum and colleagues have been compiling a NASA landslide catalogue<\/a>, with a focus on rainfall-induced landslides, to help with their work on landslide climatology<\/a>.\u00a0 In a move that we should all welcome, this dataset has now been placed online and can be accessed via a web-based GIS application<\/a>.\u00a0 The is an incredibly helpful and powerful tool, both for understanding the nature and distribution of the hazard and for teaching.\u00a0 There are a range of different ways to plot the data, allowing the user to tailor the analysis to his or her needs.<\/p>\n

As an illustration, this is the global distribution of landslides in the dataset, plotted in terms of fatalities (i.e. the size of the dot represents the number of deaths in each event).\u00a0 The smallest dots are events in which no fatalities occurred:-<\/p>\n

The map shows the extraordinary role of Asia in terms of landslide impacts, of course.\u00a0 But as expected, it also highlights the role of reporting in the nature of these types of databases.\u00a0 Thus, for example, the USA has a very large number of recorded events in the NASA landslide catalogue, with few recorded fatalities.\u00a0 The same applies to the UK and New Zealand.\u00a0 In comparison, Africa as a continent has few recorded landslides, but the majority appear to be associated with loss of life.\u00a0 This is unlikely to be the case in reality; the difference is merely the quality of reporting (especially the availability of online media and issues associated with languages).\u00a0 This is the reason that my own work has focused only on fatal landslides<\/a> – it is more likely that landslides that cause loss of life will be reported reliably, and thus the dataset is probably more homogeneous (although very far from perfect). Of course collecting data on fatal landslide introduces other biases (the location of people, vulnerability, etc), so no dataset can be said to be superior to any other.<\/p>\n

It is unlikely that these biases can be overcome completely for a hazard as complex as a landslide, but providing additional means to collate data is very helpful.\u00a0 So, it is now possible to provide information to add to the NASA landslide catalogue.\u00a0 This can be undertaken using the Landslide Reporter<\/a> tool. It is hoped that this will greatly improve the quality of the dataset, especially in those areas in which data is quite sparse at present.<\/p>\n

As an aside, Melanie Froude and I have a paper in review on our work on global landslide impacts<\/a>.\u00a0 The journal is Natural Hazards and Earth System Sciences<\/a>, which has an open review process, so anyone can download and comment upon the paper.\u00a0 We would be delighted to hear your views.\u00a0 We think that the data shows that the impact of human induced landslides is increasing.<\/p>\n","protected":false},"excerpt":{"rendered":"
