| | Abstract | | In case that a construction which excites large vibrations on the surface-ground will be scheduled, railway operators suspend an earthquake early warning system at a site to avoid the malfunction by construction vibrations. In this report, therefore, we made measurements of various construction vibrations and evaluated the wave propagation at a site, to understand construction vibration characteristics. Moreover, we performed array microtremors observations and surface wave explorations to understand a shallow subsurface S-wave velocity structure in a site. |
