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 mini workshop in creating escape map in an event of emergency was held this afternoon. Two teams were formed and tasked with assessing time required by residents around Saitama University to reach the evacuation point once an emergency occurs. Photos of the two maps are attached here (green area represents evacuation points (3 in total)).
It was quite interesting to find after the workshop that missing one street when creating the escape map changes quite a lot (apparent from distinct colour change in area around top right corner)!
