Level-2 earthquakes such as the 1995 Kobe earthquake are defined scarce to occur during the lifespan of structures but necessary to consider by performance-based design. During the Level-2 earthquake, ground becomes more susceptible to liquefaction, resulting in larger settlement, uplifting and lateral spreading. With this back-ground in mind, the Committee for Liquefaction in the Level-2 Earthquake carried out data collections, sample analyses and made discussions based on them. Among major results obtained, the definition of liquefaction for Level-2 earthquake and case history studies on road bridge damage during level-2 Kobe earthquake are addressed.
