Research overview:
General severe seismic observation for public civil engineering facilities administrated by Ministry of Construction was started by installing a SMAC type severe seismometer at Sarutani Dam within the territory of Kinki Regional Construction Bureau in 1957. As of March 1998, observations have been conducted at 873 earthquake observation facilities attached to river, road, dam and sand arresting facilities administrated by Ministry of Construction, Hokkaido Development Bureau and Okinawa General Development Office, and observed seismic waves have actively been used for studies on aseismatic design standards and seismic characteristics of various fabrics.The present subject purposes to conduct maintenance and inspection, retrieval of seismic record and numerical processing as motion check of the severe seismometer once a year by taking observing facilities installed by Ministry of Construction at river facilities among the general severe seismic observation. In the fiscal 1999, we conducted maintenance and examination of severe seismometers at 27 locations, collection and processing of records, and together technical guidance concerning "Disposition Program for Severe Seismometer at River Banks (the third period)" led by River Bureau.
