A gravity survey made some 30 years ago on the Island of Trinidad shows a negative anomaly of about 8 mgal over the Maruga Bouff mud volcano. An analysis of this anomaly is made, using an iterative three‐dimensional (3-D) modeling technique. The resulting model shows low‐density material superimposed on an underlying diapiric uplift. By comparison with other mud volcanoes which have been drilled, the model is considered reasonable.
