Multi-hazard risk assessment training

Training Course
Versed Professional Services Limited (VPSL)
16-25 Oct 2017
Kenya (Nairobi)
Appleton Resort, Sports Road, Westlands


This course deals with the procedures to collect, analyze and evaluate spatial information for risk assessment from natural and human-induced hazards (such as geological hazard, hydro-meteorological hazards, environmental hazards and technological hazards). The course will guide you through the entire process of risk assessment, on the basis of a case study of a city exposed to multiple hazards, in a developing country (Risk City).  Also, a number of case studies are used from Europe (Italy, France), China, and Georgia. 

Training objectives

  • Understand the concepts of hazard assessment, elements at risk mapping, vulnerability assessment, and risk assessment;

  • Formulate the spatial data requirements for risk assessment; 

  • Generate elements at risk data base using GIS;

  • Formulate the requirements of hazard data and methods;

  • Apply various methods for vulnerability assessment;

  • Generate risk maps using qualitative and quantitative methods;

  • Have insight in how a risk assessment could be carried out in your own situation


8 days

Training content

The course is composed of a number of Modules. Below is a summary of the Modules and detailed content.

Module 1: Introduction to risk assessment

  • Theory: Introduction to disaster risk management and risk assessment.

  • Exercise: Generation of a hazard profile using disaster databases; Introduction to ILWIS, and introduction to the RiskCity dataset. Learn the various hazard problems by evaluating high-resolution images

Module 2: Obtaining spatial data for risk assessment

  • Theory: Presentation of data requirements for the various types of hazards. Sources of spatial data.

  • Exercises: Defining spatial data requirements for risk assessment; Internet search for information on risk assessment; acquiring free and low-cost data; generating three-dimensional image data using Google Earth; stereo image interpretation

Module 3: Hazard Assessment

  • Theory: Hazard types; Main concepts of hazard assessment; Frequency magnitude – relationships

  • Exercises: Frequency assessment; Selection of hazard assessment example (flooding, landslides, earthquakes, technological hazards, volcanic hazards etc)

Module 4: Elements of risk assessment

  • Theory: Types of elements at risk; classification of buildings, infrastructure, lifelines, critical facilities; population information; a collection of elements at risk information.

  • Exercise: Generating elements at risk database from scratch; Generating elements at risk database using available data (building footprint map, census data, and LiDAR)

Module 5: Vulnerability assessment

  • Theory: Types of vulnerability; social vulnerability; physical vulnerability; methods for vulnerability assessment; participatory GIS; Spatial Multi-Criteria Evaluation
