In the Japanese Islands, coastal area can be proposed as an investigation site for geological disposal of high-level radioactive wastes. For an assessment of fault activity in coastal area, offshore surveys such as acoustic profiling and boring should be examined as well as inland surveys. In addition, adequate understanding spatial distributions and characteristics of faults in the coastal area of Japan will contribute to safety assessment for the geological disposal in such area. In this report, we collected and compiled previous studies focused on spatial distribution, continuity, timing of displacement and recurrence interval of faults near coastline, specifically faults along or across a boundary between land and sea, and technologies of survey and assessment for them.
