| Linear infrastructures such as power transmission lines, water pipelines, railways, highways and levees should be kept continuous to function as networks for logistics or for protecting habitation areas from flooding. Even a small break might cause entire loss of the original function of each linear infrastructure. Therefore, vulnerability assessment is crucial for linear infrastructure network along the network. Conventional risk assessment of linear infrastructure has been conducted making 2D information from ill-posed and low-reliable geotechnical boring data, ignoring small-scaled local anomaly. Conversely, near surface geophysics can provide detailed 2D, 3D, or 4D continuous geospatial information. Accordingly, near surface geophysics can play an important role for the seismic resilience of linear infrastructure. Integration of several geophysical techniques is essential for deep understanding of the near surfaces. Moreover, near surface geophysicists should stand on the viewpoint of target oriented instead of method oriented. Comprehensive approaches from not only geophysics but also from geoscience and geotechnical engineering are crucial for enhancing seismic resilience of infrastructure. |
