This paper introduces a multi-hazard and multi-risk assessment methodology adopted from literature review, which combines single risk assessment and a three-level risk assessment. | MULTI-RISK AN APPROACH FOR DISASTER RISK MANAGEMENT Huynh Thi Lan Huong Tran Thanh Thuy Viet Nam Institute of Meteorology Hydrology and Climate Change Received 20 June 2017 Accepted 21 August 2017 Abstract Natural disaster risk assessment is a critical part of a risk management system. Single risk assessment which addresses different natural hazards and their associated risks separately is a popular one used in risk management in Viet Nam. Single risk assessment deals with only one source of disaster ignoring all the possible risk interactions. A multi-risk approach therefore has currently been developed and tested by a number of scholars. This paper introduces a multi-hazard and multi-risk assessment methodology adopted from literature review which combines single risk assessment and a three-level risk assessment. Multi-risk approaches takes into account the interactions and relations among hazards and among vulnerabilities. It can bring benefits but also challenges to both end-users and scientists. Keywords multi-risk multi-hazard disaster risk reduction. 1. Introduction Located in the tropical monsoon area Viet Nam is one of the most disaster-prone countries in the world. Due to its geographic location and topography such as a long coastline Viet Nam suffers from multi natural disasters including typhoons tropical cyclones tropical storms floods droughts saline water intrusions landslides and earth quakes. In recent years in the course of a changing climate natural disasters in Viet Nam have been increased significantly in terms of magnitude frequency and volatility. Between 1990 and 2016 natural disasters claimed almost 12 000 lives and caused GDP losses of 1 to 1.5 per year 7 8 . Therefore natural disaster risk management including prevention and mitigation require appropriate approaches and methodologies to address these issues. Single risk approaches deal with only one source of disaster and its relevant vulnerability of exposed elements. Single risk .
