  1. (x0, y0) is the horizontal location of the center of the Mogi source, D its depth, a its radius and ∆P the internal hydrostatic pressure, respectively. dF are the computed values. The origin of the horizontal coordinates is taken at (14.01°N, 121.00°E), which is located around the center of the MCL
