Detailed Imaging of Near-surface Faulting Structure using Land Streamer

Delineation of near-surface deformation structure is essential to characterize the recent behavior<br>of active fault system and to estimate its near future activity. Although a combination of exploratory<br>trenching and drilling has been widely adopted to reveal deformation history of active faults for the<br>paleoseismological studies in Japan, it was difficult to delineate the faulting structure by such “pinpoint”<br>surveying.
