| Research Abstract |
It was clearly revealed that the ground of the Mexico city basin was deposited under the environmental condition of a very gentle flow of fresh water. The ground of Mexico city had the property that was hard to damp for the earthquake. This shows that seismic motion will be continued for a long time at the time when an earthquake occurs. In addition, it was found that there was the close relation between the bedrock depth and the vibration properties in Mexico city basin. Thus, if it can be realized the location in the basin, it will be able to estimate the seismic properties.
