Microtremor Observation II

Course Description

Among many techniques for investigating subsurface shear wave velocity structure, microtremor (or ambient vibration) observation is efficient and cost-effective approach for exploration of soils and sediments. In this lecture, basics of microtremor observation techniques and data processing procedures are introduced. Field exercises on single and multiple observations will be conducted.
