Earthquake Disaster Prevention and Mitigation Group (EDPMG) is one of the research groups under the Department of Civil and Environmental Engineering of Saitama University

As apparent from the name of our group, we conduct research with primary focus on earthquakes. Various branches of work that are being carried out under the vast field of earthquake engineering are (including but not only limited to):

  • Evaluation of building vibration characteristics and collapse behaviour using observed seismic motion and numerical analysis
  • Influence of site and propagation path on strong ground motions
  • Research on strategies for creating disaster-resilient communities (development and social implementation of resilient structures)
  • Development of accurate estimation methods for disaster sites using digital twins
  • Evaluation of evacuation route during disasters using GIS
  • Analysis of factors resulting in regional differences in seismic retrofitting rate
  • Dynamic interaction between soil and structures during earthquakes (SSI)
  • Evaluation of the impact of seismic faults on linear structures such as railways and roads and their application to design
  • Assessment of the integrity of social infrastructure facilities (such as dams) using observed seismic motion
  • Verification of the effectiveness of evacuation signage using 3D virtual space (VR)
  • Development of semi-active base isolation systems using deep reinforcement learning
  • Research and development of seismic countermeasures for resilient cultural properties and artifacts

A joint technical online seminar between Chittagong University of Engineering and Technology (CUET) and Saitama University (SU) was held on March 15, 2022, led by Assoc. Prof. H Taniyama from SU side. From CUET side, Assoc. Prof. Md. Aftabur Rahman and his research group participated in the event. Technical presentations were made from both sides, both by the faculty members and students. At the end of the seminar, discussion on future collaborations was carried out. A screenshot of the seminar showing participating members is posted here.

As a part of student activities, Japanese and international master’s students of our group visited Sendai (Miyagi) on Nov. 21 to learn about the reconstruction efforts in the aftermath of 2011 Great East Japan Earthquake. The full-day trip provided a good platform for the visiting members to see and understand the reconstruction.

The same visiting members also participated in two online real-time special lectures given by Assoc. Prof. Phan Huy Dong of Hanoi University of Civil Engineering, Vietnam on Dec. 9 and Assoc. Prof. Nakhorn Poovarodom of Thammasat University, Thailand on Dec. 15. The lectures covered various interesting research aspects in the fields of structural and geotechnical engineering and at the same time highlighted the link between research and industry.

Report on the activity can be seen from here:

Yuki Mizukawa of our group won the 'Excellent Master Thesis Award' for the academic year 2020. His master's thesis research work is titled "On the technique for early detection of dangerous buildings using aerial video footages in the aftermath of an earthquake (地震直後の危険な建物を空撮動画から早期検出する手法の研究)".

Conferred by the Department of Civil and Environmental Engineering, the award honours master's students who conduct excellent master's research and make outstanding final presentation. Of all the master's graduate of 2020, only 2 other students besides Yuki Mizukawa were awarded the excellent master thesis award. We congratulate him for this achievement!
