The survey employed a Tromino® instrument for single-station ambient noise measurements, using a dense deployment of acquisition points distributed across the mud volcano area.nnThe dataset includes 21 files in SESAME ASCII Format (.saf) v.1, one for each sampled site (DMT01–DMT21). Each measurement lasted 30 min. These data were used in the following publication:nnPetrosino, S., Madonia, P., Gucciardo, D., and Cusano, P.
