Pre-Disaster Information Lab
Machine-translated · View original
The lab investigates the ground to communicate the risk of slope disasters.
AboutAbout the lab
Recognizing the possibility of disaster and preparing for it.
The lab studies slope disasters, which have become increasingly compound and severe in recent years, and conducts research on "Misaigaku" (pre-disaster science), a new concept originating in Japan that contributes to disaster prediction and better disaster-prevention literacy.
The lab develops methods for evaluating slope information and for putting it to practical use in society by disseminating pre-disaster information.
Key terms
- Geophysical exploration
- A method of investigating underground structure without digging, using seismic waves, electricity, and similar means
- Surface wave survey
- A method that measures waves traveling along the ground surface to determine the stiffness of shallow ground
- Hazard map
- A map showing where disasters are likely to occur and the degree of danger
ResearchResearch themes
The lab develops methods for evaluating slope information and for putting it to practical use in society by disseminating pre-disaster information.
*Illustrative imageDeveloping Geophysical Exploration Methods
The lab develops better exploration and analysis methods for ground investigation, using seismic refraction surveys, surface wave surveys, microtremor array surveys, wavefield simulation by the finite-difference method, vibration measurement with optical fibers (distributed acoustic sensing, DAS), and machine learning.
*Illustrative imageSediment Disaster Risk and Disaster Education
The lab studies the mechanisms by which sediment disasters occur, creates slope failure hazard maps, creates sediment disaster hazard maps with resident participation, and conducts research on disaster-prevention education for the general public.
