Meguro-Ohara-Numada Lab
Machine-translated · View original
A disaster prevention lab that reduces damage from earthquakes and other disasters through both hard and soft measures.

AboutAbout the lab
Disaster prevention research combining hard and soft measures.
The Meguro-Ohara-Numada Lab studies strategies to minimize the damage and the disruption to social functions caused by disasters such as earthquakes.
The lab places importance on a balanced combination of hard measures, such as strengthening buildings, and soft measures, such as information, institutions, and training.
Together with residents and government officials, the lab studies and demonstrates disaster prevention systems that link everything from analyzing the phenomena that cause disasters and estimating damage to disaster response.
Faculty specializing in urban earthquake disaster mitigation engineering, disaster risk reduction, and disaster prevention process engineering supervise students.
Key terms
- Applied Element Method
- An analysis method that models a structure as a collection of small elements connected by springs, and calculates its behavior until it breaks and collapses
- Masonry construction
- A way of building by stacking bricks, blocks, stones, and the like. It is common in housing in developing countries
- Seismic retrofitting
- Adding reinforcing materials to an existing building so that it is less likely to be damaged by earthquake shaking

ResearchResearch themes
The lab studies strategies to minimize human and physical damage and the disruption of social functions caused by natural disasters, mainly earthquakes, by taking a balanced combination of hard and soft measures. Its research aims to make three goals concrete: “damage prevention,” “disaster response and damage mitigation,” and “optimal recovery and reconstruction.”
*Illustrative imageSimulating Collapse with the Applied Element Method
Using the Applied Element Method (AEM), which the lab continues to develop, the lab analyzes how structures break in earthquakes, all the way to complete collapse. Targets include railway viaducts, underground structures, and fault movement.
*Illustrative imageMaking Masonry Houses Earthquake-Resistant
Masonry houses built by stacking bricks or stones can collapse in an instant in earthquake shaking. The lab proposes seismic retrofitting methods using PP bands and fibers, and verifies their effectiveness through shake-table experiments and numerical analysis.
*Illustrative imageDebris Flow Simulation
This research uses a computational method called the Extended Distinct Element Method to reproduce on a computer debris flows, in which rocks and soil rush downhill all at once.
*Illustrative imageThinking About Evacuation from the Users' Perspective
The lab develops tools that evaluate the safety of urban spaces based on users' evacuation behavior and simulate that behavior. Targets include evacuation from high-rise buildings, evacuation inside trains, and evacuation during tsunami disasters.
