We have applied the micro-tremor array measurements (MAM) to shallow S-wave velocity<br>investigations and evaluated the applicability of the method. Unlike the active surface wave methods,<br>the MAM does not need any sources and needs two-dimensional arrays, such as triangles, circles or<br>crosses. Because the sources of the microtremor are distributed randomly in space, the microtremor does<br>not have any specific propagation directions.
