SLIDE 11 | Multi-hazard Risk Assessment at District Level in Tajikistan |
Proposed method for national scale risk assessment in Tajikistan
If intensity class maps can be generated
Risk = Hazard * Vulnerability * Amount
Probability of event happening Consequences or losses * =
Risk = Expected losses in a given time period
Quantification of Exposed Elements at risk Degree of loss to Elements at risk Per frequency class * * =
Hazard type Number of events Average size of event Total area affected Hazard classes
Hazard Types Physical Vulnerability Elements-at-risk
Buildings Population Roads Forest Crops Buildings Population
Exposure: Spatial overlay of hazard and elements at risk
Mud flows Earthquake Drought Windstorms Buildings Population Roads Forest Crops
Exposed Elements-at-risk Hazard
(matrix of frequency and intensity classes)
Risk Profile per administrative unit: Per village Per municipality Per District
Mud flows Earthquake Drought Windstorms Mud flows Earthquake Drought Windstorms
Frequency Hig h Moderate Low Low Moderate High Intensity classes Per village
Roads Forest Crops
Per Municipality (Jamoat)
Socio- economic indicators
Per village Holistic vulnerability assessment
