The All-Hazards Risk Assessment methodology (AHRA) assesses the impact and likelihood of all-hazards that pose threat to Canada. It informs our collective ability to mitigate their impacts: the All-Hazards Risk Assessment methodology and the Capability-Based Planning methodology. The National Risk Profile uses two evidence-based methodologies to assess Canada's current level of risk to all-hazards. Provide evidence to inform on capabilities to build resilience.Generate a national picture and evidence to compare risks across domains and.Enhance information-sharing by promoting a whole-of-society approach to risks and capabilities.Improve awareness and understanding of disaster risks through biennial public reports (one report published every two years).Provide a common lexicon and methodologies for the assessment of all-hazards, including climate influenced and natural hazards.What are the benefits of having a National Risk Profile? In future years, the scope of the National Risk Profile will expand to include a broader range of natural hazards, eventually encompassing all-hazards, including those that are human-induced. The first stage focuses primarily on floods, wildfires and earthquakes. The National Risk Profile is being implemented in stages. What does the National Risk Profile evaluate? Public Safety Canada is working in collaboration with provincial and territorial governments, Indigenous leadership and communities, as well as industry experts to evaluate the current level of risk Canadians face and our capacity to respond to those risks. The National Risk Profile supports the second priority under the Emergency Management Strategy for Canada: Towards a Resilient 2030, which is to improve understanding of disaster risks in all sectors of society. About the National Risk Profile Overview of the National Risk Profile The National Risk Profile is a strategic national disaster risk and capability assessment that uses scientific evidence and stakeholder input to create a forward-looking picture of Canada's disaster risks and capabilities in order to strengthen Canadian communities' resilience to disasters, such as floods, wildfires and earthquakes.

The accuracy of the receiver operating characteristic (ROC) reached 0.720, which was higher than that of the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability (TRIGRS) model (0.620). The results showed that FSLAM could accurately capture the effect of rainfall on PoF of slopes, and more than 70% of the landslide were identified in very high/high hazard zones. ![]() Finally, the landslide hazard map was generated for the study area to reflect the landslide risk. Considering the randomness and uncertainty of soil and vegetation parameters on the regional scale, FSLAM model computes the probability of failure (PoF) by using random parameters inputs. Five input raster files (elevation, soil types, vegetation, antecedent rainfall, event rainfall) and two parameter files regarding soil properties and vegetation were determined. In August 2015, a total of 123 landslides induced by Typhoon Soudelor in Wenzhou City, southeastern China, was taken as an example. This study aims to investigate the application of a physically-based model named after the fast shallow landslide assessment model (FSLAM) to rainfall-triggered landslide hazard assessment. ![]() Landslide hazard assessment is an important component of risk management and land-use planning. ![]()
