Results of heat flow measurements in the centers of three basins in the NW Banda Arc carried out during the Indonesian-Dutch Snelliusm II expedition in 1985 all show high heat flow values. The average heat flow in the north Buru basin, on the outside of the arc,is 161 mW/m2. Two small, NS to NW-SE elongated subbasins situated in the Liucipara basin show heat flow values of 175 and 134, mW/m2, respectively. The high heat flow measured in both the north Buru and Lucipara basins is interpreted to be the result of recent EW strike-slip movement in the northwestern Banda Arc. ¿ American Geophysical Union 1987
