The Shimajiri formation,which is stratified predominantly by tuff beds,silty clay layers (mud-stone) and silty sand layers (silt or sand-stone),can be separated into three groups of Shinzato,Yonabaru and\nNaha.Two of them; the Yonabaru and Naha groups are naturally found in Naha-city. The formation is widely exposed in this area and is the foundation on which younger rocks of the Ryukyu limestone have been deposited.The Ryukyu limestone is a general term for Naha,Yomitan and Makiminato limestone,The Naha limestone which is found in Naha-city is exposed at the west side of highway 58,Shuri hill, Shikina hill etc.\nRaised reef limestone and Beach deposits are developed along the sea shore. Also muds are deposited at\nthe bottom of Asato,kumoji and Kokuba river.In particular,the thickness of the mud is about 20 meters at Manko which is the mouth of Kokuba river.The fountains out of the Ryukyu limestone are found at Shuri\n,Shikina and Yam-ashitacho.Some of them are used for domestic pauposes. In this report no physical and\nstrength laboratory test results are evaluated. Typical subsurface section through boring holes are presented.
