| Recognizing the importance of an information network at the time of an earthquake after the Kushiro Offshore Earthquake in 1993，the Hokkaido Development Bureau has developed an on-line digital infomation seismograph，and established the Warning Information System of Earthquake（WISE）．The importance of earthquake damage informationnetworks has also been recognized nationwide since the Great Hanshin Earthquake in January 1995．[*]In establishing WISE，emphasis was placed on understanding damage and securing a data communicationnetwork，based on the lessons learned from three major earthquakes in Hokkaido．This system is for supporting the disaster-prevention system at the start of an earthquake．Existing and new strong motion seismographs installed on bridges，river dam bodies，in damagement offices and other places are connected on-line to obtain more accurate information more promptly． |
