NASA models landslide climatology<\/h4>\n

In the last few days, NASA has released a range of new materials and data to understand global landslide occurrence<\/a>.\u00a0 This work, which excellent as ever, has emerged from the team led by Dalia Kirschbaum<\/a>, with substantial input from Thomas Stanley<\/a> and others.\u00a0 The volume of material is far too great for a single post, so here I will focus here just on their work on global landslide climatology<\/a>.<\/p>\n

The NASA team have developed a new model, Landslide Hazard Assessment model for Situational Awareness (LHASA)<\/a>, which determines landslide susceptibility every 30 minutes.\u00a0 The NASA webpage<\/a> describes the model thus:<\/p>\n

This model uses surface susceptibility (including slope, vegetation, road networks, geology, and forest cover loss) and satellite rainfall data from the Global Precipitation Measurement (GPM) mission<\/a> to provide moderate to high \u201cnowcasts.\u201d<\/em><\/p>\n

Associated with this work, NASA have placed online<\/a> a series of animations, all of which can be downloaded (and so represent excellent teaching resources).\u00a0 The animations are made on a monthly basis, and in each case they run twice – first showing merely the climatology, and second with the landslides from the NASA landslide database overlain.\u00a0 So this, for example, is the animation for August, a key landslide month globally, with the landslide events overlain:-<\/p>\n

Whilst this image shows the landslide climatology for Asia only, without the landslide events overlain, for the same month:-<\/p>\n

The animations serve to illustrate beautifully both the highly susceptible areas of the Earth’s surface, and the changing pattern through the annual cycle.\u00a0 I have frequently noted the global landslide cycle<\/a>, with the peak in July and August, and the incredible importance of South and East Asia in defining this pattern<\/a>.\u00a0 These NASA animations provide further evidence.<\/p>\n

If we are to reduce losses from landslides then Asia needs to be a key focus.<\/p>\n","protected":false},"excerpt":{"rendered":"
