Thermal Correction for Moho Depth Estimations on West Philippine Basin: A Python Code to Calculate the Gravitational Effects of Lithospheric Cooling Under Oceanic Crust

The aim of this work is to present an easy-to-use Python code to calculate the gravitational effect due to lateral variations in the thermal structure of oceanic lithospheric plates, necessary to appropriately isolate the contribution of the variations in crustal thickness. The model is applied to calculate the Moho depth in the West Philippine Basin, and the results are compared with seismic data. The estimations of the Moho depth taking into account the thermal correction presented a better fit with the seismic data and smoother geographical variations than the model without thermal correction.
