1 Damage by 1799 Kanazawa Earthquake in Relation to Fault Movement Akira SANGAWA Geological Survey of Japan (Received October 18, 1986) In the evening of June 29, 1799, a strong earthquake occurred in an area which is presently a part of the Kanazawa City. The damage and its location are thoroughly described in old documents. The Kanazawa Castle was severely damaged. Stone wall collapsed and warped in many places. Small vertical displacement occured on the ground in front of the Ishikawa Gate. In the city, Ohtesaki, Ohmi-cho, Hikoso-machi, Misogura-cho, Kotatsuno, Utatsu-cho and Ohhi-machi were severely damaged. In these areas, the intensity of the shock is inferred to be of the order of VI-VII. Many stone lanterns jumped up nearly 2m, showing that main shock was vertical in these areas. The locations of severe damage were situated along the Morimoto Fault, trending NE-SW in the north to central part of the city. Especially, the damage was serious on the southwestern end of the fault. The earthquake is believed to be caused by the Morimoto Fault with the epicenter located at the southwestern end of the fault.
