The paper has attracted some attention in Turkey – for example there is an article in the newspaper Hurriyet Daily News that highlights the key findings<\/a>.\u00a0 It notes that over the 90 year period of the study a total of 1,343 people were killed in 389 fatal landslides in the country, making landslides the second-most deadly hazard, after earthquakes.\u00a0 However, the study has also found that the average number of fatal landslides has increased substantially to 12.2 over the last two decades, increasing the average number of due to landslides to 23.6 per year. As usual this is probably driven mainly by the availability of better data for recent years, but there might also be an increase in losses as the population has increased and the environment has been degraded.<\/p>\n Perhaps the most interesting finding in the study is shown in the figure below, from G\u00f6r\u00fcm and Fidan (2021)<\/a>:-<\/p>\n The natural and physical processes driving landslide losses in Turkey. The black dots are the fatal landslide events. The upper map is a combination of slope gradient and annual rainfall. The lower map is a combination of slope gradient, annual rainfall and population density. Diagram from G\u00f6r\u00fcm and Fidan (2021)<\/a>.<\/p><\/div>\n .<\/p>\n The two maps show the fatal landslide events (black dots) underlain by a combination of average annual precipitation and slope gradient in the case of the upper panel.\u00a0 This explains the distribution of landslides quite well, although there are landslide clusters around the major urban areas for which the model cannot account.\u00a0 In the lower panel the population density is added to the algorithm.\u00a0 This combination does a good job of accounting for the spatial distribution of losses.<\/p>\n Of particular note is the hotspot of landslide susceptibility in the northeast of the country.\u00a0 As this area is densely populated, landslide losses here are high.<\/p>\n It is interesting that a number of studies have now shown that at the national or global level, the best spatial predictor of losses in fatal landslides is a simple combination of slope angle, annual precipitation and population density.<\/p>\n It is the aim of many of us working in landslide research to reduce loss of life in these events.\u00a0 Understanding the patterns in time and space is a key part of this; these national level studies are immensely valuable.<\/p>\n .<\/p>\n![\"The](\"https:\/\/blogs.agu.org\/landslideblog\/files\/2021\/01\/21_01-Turkey-1.jpg\")
