Outlining microtremor array survey: With a view to application to shallow geological surveys

Abstract

A microtremor array survey is a tool for modeling subsurface S-wave velocity structure using small ground oscillations, or microtremors, which can be recorded by multiple seismometers at the surface. This paper presents an overview of the method, including the principles, some warnings, and an example survey. In some parts, we focus on the application of the method to shallow geological surveys, to depths of several tens of meters. For further interested readers, we finally list the pieces of literature for review.
