“…In contrast to other natural hazards (e.g., floods or earthquakes), which affect large areas, landslides are generally limited in area but can occur with a high frequency in a specific region (JRC 2011). Landslides can be caused by both natural and anthropogenic actions, and landslide disasters are increasing worldwide (Andersson-Sköld et al 2014;Guzzetti 2016;Ho et al 2013;Nadim et al 2006;SOU 2007). The reasons are suspected to be increased susceptibility of surface soil to instability because of deforestation and overexploration of natural resources, greater vulnerability of exposed population as a result of urbanization and uncontrolled land use, and climate change resulting in a greater potential for weather extremes (Lacasse et al 2010;Nadim et al 2006).…”

Quick clay landslides are a special feature of Norwegian and Swedish geologies. Vibrations or small initial landslides can cause a quick clay layer to collapse and liquefy, resulting in rapid landslides with little or no time for evacuation, making them a real threat to human life. Research concentrating on damages due to landslides is scarce, and analyses of loss of human lives caused by quick clay landslides in the scientific literature are, to our knowledge, nonexisting. Fatality quantification can complement landslide risk assessments and serves as guidance for policy choices when evaluating efficient risk-reducing measures. The objectives of this study were to assess and analyze available damage information in an existing data set of 66 historical landslide events that occurred in Norway and Sweden between 1848 and 2009, and access its applicability for quantifying loss of human life caused by quick clay landslides. Fatality curves were estimated as functions of the number of exposed persons per landslide. Monte Carlo simulations were used to account for the uncertainties in the number of people actually exposed. The results of the study imply that the quick clay fatality curves are nonlinear, indicating that the probability of losing lives increases exponentially when the number of exposed persons increases. Potential factors affecting human susceptibility to landslides (e.g., landslide-, area-, or individual-specific characteristics) could not be satisfyingly quantified based on available historical records. Future research should concentrate on quantifying susceptibility factors that can further explain human vulnerability to quick clay landslides.

“…The elimination of duplicate records allowed the identification of 200 papers to be screened (Figure 1). Then, article screening allowed us to eliminate 137 papers that did not analyze landslide mortality, even if their titles included the search terms (i.e., [12][13][14]).…”

Landslides triggered by rainfall kill people worldwide, and frequent extreme events that are expected to be an effect of climate change could exacerbate this problem. This review aims to identify recent research, highlighting both the dynamics of landslide accidents and the characteristics of victims. From SCOPUS and WOS databases, using the PRISMA (preferred reporting items for systematic reviews and meta-analysis) approach, 25 articles written in English, published in the January 2010–March 2022 period and focused on landslide fatalities, were mined. The selected articles recognized a worldwide underestimation of landslide fatalities and analyzed landslide mortality from three perspectives, indicating the importance of this topic for a multidisciplinary research community. The papers focused on (a) fatal landslides and their geographic distribution, seasonality, trends, and relationships with socioeconomic indicators; (b) landslide fatalities and their behaviors and the dynamics of accidents; and (c) clinical causes of death or injury types, aiming to improve emergency rescue procedures. The gaps that emerged include (a) the insufficient reuse of valuable fatality databases; (b) the absence of simple take-home messages for citizens, practitioners, schoolteachers, and policymakers, aiming to set educational campaigns and adaptation measures; and (c) the lack of joint research projects between researchers working on landslides and doctors treating victims to provide complete research results that would be able to actually reduce landslide mortality.
