| "The October 23, 2004 Mid Niigata Prefecture earthquake of magnitude 6.8 in JMA scale and the subsequent aftershocks, which struck the inland area of Niigata prefecture, was the most severe earthquake to affect Japan since the 1995 Hyogo-ken Nambu earthquake. The earthquake resulted in 46 deaths and three thousand injuries. It also destroyed over 90,000 houses.A reconnaissance survey was conducted under the cooperation of NILIM and PWRI to observe, document and summarize the damage and learn lessons from this earthquake that can be used to mitigate the impact of future earthquakes.This paper briefly summarizes the information collected during as well as following this investigation. The paper includes information on geology, landslides, damage to road facilities and sewerage systems. Other lifeline systems and buildings were out of scope of the survey. Damage to dams is not described as they are to be reported in a separate paper." |
