Landslide hazard and risk zonation—why is it still so difficult?
TLDR
In this paper, the authors review the problem of attempting to quantify landslide risk over larger areas, discussing a number of difficulties related to the generation of landslide inventory maps including information on date, type and volume of the landslide, the determination of its spatial and temporal probability, the modelling of runout and the assessment of landslide vulnerability.Abstract:
The quantification of risk has gained importance in many disciplines, including landslide studies. The literature on landslide risk assessment illustrates the developments which have taken place in the last decade and that quantitative risk assessment is feasible for geotechnical engineering on a site investigation scale and the evaluation of linear features (e.g., pipelines, roads). However, the generation of quantitative risk zonation maps for regulatory and development planning by local authorities still seems a step too far, especially at medium scales (1:10,000–1:50,000). This paper reviews the problem of attempting to quantify landslide risk over larger areas, discussing a number of difficulties related to the generation of landslide inventory maps including information on date, type and volume of the landslide, the determination of its spatial and temporal probability, the modelling of runout and the assessment of landslide vulnerability. An overview of recent developments in the different approaches to landslide hazard and risk zonation at medium scales is given. The paper concludes with a number of new advances and challenges for the future, such as the use of very detailed topographic data, the generation of event-based landslide inventory maps, the use of these maps in spatial-temporal probabilistic modelling and the use of land use and climatic change scenarios in deterministic modelling.read more

TL;DR: In this article, a complete landslide geodatabase of the Messina Province, designed following the requirements of the local and national Civil Protection authorities, is presented This geo-database was used to produce maps (e.g., susceptibility, ground deformation velocities, damage assessment, risk zonation) which today are constantly used by the civil protection authorities to manage the landslide hazard of the messina Province.

Assessing vulnerability of buildings to hydro-meteorological hazards using an expert based approach : an application in Nehoiu Valley, Romania
TL;DR: A new expert based approach that allows physical vulnerability assessment of buildings to hydro-meteorological hazards in areas with limited information about the hazard or the exposed elements and it can be used for decision-making support in disaster response and risk management.

Integration of two-phase solid fluid equations in a catchment model for flashfloods, debris flows and shallow slope failures
TL;DR: Results show that the model can recreate the impact of both shallow landslides, debris flow runout, and debris floods with acceptable accuracy and general patterns in slope failure and runout are well-predicted, leading to a fully physically based prediction of rainfall induced debris flood behavior in the downstream areas.

TL;DR: In this paper, the authors used geomorphological information to assess areas at high landslide hazard, and help mitigate the associated risk, and found that despite the operational and conceptual limitations, landslide hazard assessment may indeed constitute a suitable, cost-effective aid to land-use planning.
