The 21st International Symposium on Geo-disaster Reduction held successfully
Last Updated:2023/8/21 23:26:19


In recent years, with the continuous development of marine resources, marine geological disasters have become more frequent. These disasters not only affect the construction of marine engineering projects but also pose risks to their safe operation, presenting new challenges to the development of marine system engineering. In order to enhance the exchange and discussion of key issues in the field of marine geo-disaster reduction, the 21st International Symposium on Geo-disaster Reduction was successfully held at Tongji University from August 5th to 8th.


This conference serves as the annual academic meeting of the International Consortium on Geo-disaster Reduction (ICGdR) and was jointly organized by Tongji University and the UNESCO Chair on Earth Environment and Disaster Mitigation. The conference was held in a hybrid format, combining both online and offline sessions, and attracted significant attention from numerous experts and scholars worldwide. Over 80 representatives from countries including China, the United States, Italy, Turkey, Japan, and others participated, sharing and exchanging the latest research findings.

The opening ceremony was chaired by Professor ZHENG Hu, the Secretary-General of the conference. The keynote speeches were delivered by Professor ZHU Hehua, an academician of the Chinese Academy of Engineering; Professor SHI Zhenming, Assistant President of Tongji University; Professor HUANG Yu, Head of the College of Civil Engineering at Tongji University; and Professor WANG Fawu, the President of the International Consortium on Geo-disaster Reduction (ICGdR).


Academician ZHU Hehua pointed out the frequent occurrence of marine disasters in recent years, posing potential threats to engineering construction, and emphasized the urgent need for international collaboration to explore new technologies for disaster prevention and reduction. Professor SHI Zhenming expressed sincere gratitude and warm welcome to all the participants on behalf of the university, and briefly introduced the work conducted by Tongji University in the field of disaster prevention and reduction. Professor HUANG Yu expressed gratitude on behalf of the College of Civil Engineering and organizing committee, and expressed expectations for the conference to provide new ideas for marine disaster prevention and reduction. President WANG Fawu introduced the establishment of the International Consortium on Geo-disaster Reduction and expressed hope that the attendees would focus on cutting-edge research, actively engage in discussions, and make greater contributions to disaster prevention and reduction efforts.
