The physical conditions of subsoil are related to the surface seismic response and may control it. To understand and mitigate the effects that cause damage, it is necessary to characterize the velocity structure in tens or hundreds of meters. To do this, it is required to analyze and confront the results of different geophysical methods together since the distribution of physical properties in depth occurs at different scales. Ambient seismic noise methods can be ideally suited as exploration methods. So far, there are many advances using station arrays and case studies using a single station are quickly emerging. In this session, all those works showing the advantages of high-resolution ambient seismic noise techniques for the subsoil velocity structure are welcome. We will discuss the advancement of microtremor arrays to the limitations and advantages of the HVSR method. Comparing results with other geophysical techniques will enrich the definition of application and development perspectives. We encourage presentations that illustrate the solution to problems related to seismic amplification, terrain subsidence, landslides, the presence of discontinuities, etc.
