[G03-P06] The hazard prediction models made by the students' analyzing sedimentation and building cracks.
Keywords:Active fault, volcanic sediments, Quake model, stress
Our activities has been continued as follows,
(1) Analyzing volcanic ash layers
3 volcanic terms are found. And the other hand, it was not able to find the origin.
(2) Constructing quake model
Volcanic ash layer(s) make soil ground base stronger against quake, students made fundamental mechanic models about this situation.
(3) Searching building crack
In order to mention stress from the ground, it is obviously appeared on the concrete walls in the buildings. Our location is on the boundaries between ocean plate and continental plate, typical direction(s) has been found.
