| Outline of Final Research Achievements |
The unsolved paleoseismological problem in the northern Kanto district, central Japan is that an active fault generating a great earthquake in A.D. 818 recorded by the historical formal record has not been identified. In the northwestern part of the Kanto Plain, it is well known that paleo-liquefactions, fissures or landslides due to strong shaking are observed in more than 50 archeological sites.
I tried geological and geomorphological survey with collecting archaeological data related to strong shaking during A. D. 818. Based on trenching survey, I suggested that Ota fault could be a fault corresponding to the 818 earthquake.
