The de-fractal approach was used to calculate the depth to bottom of magnetic sources (DBMS) beneath the Malay Peninsula and surrounding regions. DBMS estimates for the study area range from ~7.3 to 49.3 km with a mean value of 21.4 km. The deepest DBMS (up to 49 km) is associated with Sumatra Island, while elevated DBMS as shallow as 7 km have been documented in areas impacted by thermal springs in the western Malay Peninsula. This suggest that the hot springs in these regions are highly promising for geothermal exploration. Comparison of DBMS estimates with crustal thickness from previous studies shows that the DBMS in the Malay Peninsula region are shallower than the Moho, indicating that the curie surface is a thermal boundary layer, rather than reflecting a change in mineral composition. However, depth estimates along the Sumatra Island suggest that the upper mantle beneath the region have contributed to surface magnetisation.
