		| Scope | This session deals with stratigraphy, active tectonics and depositional system of the Pleistocene to Holocene sediments, distributed in and around the alluvial plain. Examples of discussion subjects are as follows: development process of the late Quaternary basin from the sedimentary system, sedimentary environment and its changes and sea level changes, ground disaster. such as liquefaction, in and around the sedimentary plain. |
