Quantile-based individual risk measures for rockfall-prone areas

In mountain environments, precise rockfall risk evaluation is crucial to reduce death tolls and costs. However, date, existing assessment procedures remain scarce, as they focus only on elements at with the damage expectation sole measure. Here, we propose an approach evaluate distribution of damages individual basis a continuous function space. Furthermore, evaluated through (i) based (ii) value-at-risk (VAR) (iii) expected shortfall (ES). VaR ES measures allow better assessing due extreme events accounting for various short-term/long-term constraints faced by stakeholders. This procedure applied Le Brocey slope (municipality Crolles, French Alps), frequently affected events, illustrating its potential land-use planning. Notably, obtained values can be confronted acceptability thresholds perform legal zoning sound basis. Also, comparison management strategies different behaviors towards risk, budgetary and/or temporal horizons. Hence, provides valuable tools future planning decision-making. It could easily transferred other hazards wider contribution determination best balance between safety sustainability.
