INTRODUCTION The necessity of the Thesis Hanoi, the capital of Vietnam, is the political, cultural, educational and scientific center of the country. According to the census results of 2019, Hanoi has an area of 3,324.92 km², located in 17 of the world's largest capitals, with more than 8 million people. The average population density of Hanoi is 2,398 people/km2, which is 8.2 times higher than the national average population density. Besides the high population density, the process of urbanization of the capital has also taken place rapidly in recent years. Hanoi seems to become a great construction with a series of infrastructure development projects and urban areas. In terms of natural conditions, Hanoi is a vulnerable area to earthquake hazards. According to previous studies, Hanoi is located on the fault zone of the Red river, Chay river, Lo river, and in the intensity zone level VIII (the MSK scale) on the national seismic zoning map. With the dense population in urban areas, Hanoi might suffer significant losses if an earthquake occurs. Over the past decade, great progress has been made in the methodologies of seismic hazard and seismic risk assessments in the world. This can be mentioned as follows: after a series of earthquake disasters occurred recently, the ground motion prediction equations have also been updated and newly built in accordance with the seismotectonic provinces as the NGA-WEST1, NGA-WEST2 and SHARE; building damages and casualties models have also been upgraded. With the aforementioned issues, PhD student selected the topic Urban seismic risk assessment for the Hanoi city, in order to enhance research capacity in depth on the topic of urban seismic risk assessment. Based on inheriting the results of previous studies, combined with updated data, and applying the state-of-the-art methodology for seismic risk assessment and cutting edge computing technology is performed on the GIS environment to assess seismic risk for the Hanoi urban area. The purposes of the Thesis: - Upgradation and enhancement of the urban seismic risk assessment tool in Vietnam based on the inherent results of the previous studies and the cutting-edge methodology of seismic risk assessment in the world. - Development of a realistic portrayal of seismic risk for the Hanoi urban area based on the state-of-the-art methodologies for seismic risk assessment and updated dataset. The main contents of the Thesis: - Assessment of seismicity for Hanoi city and adjacent areas. - Seismic hazard assessment for Hanoi city. 1 - The correction of ground motion amplification for Hanoi urban area - Seismic risk assessment for Hanoi urban area. New contributions of the Thesis: - Upgradation and enhancement of the urban seismic risk assessment tool called ArcRisk, with the function of a decision support system, operating in the GIS environment. ArcRisk was built based on World’s advanced methodologies such as Hazus-MH, Openquake, with modifications to suit the application conditions in Vietnam. - ...
