'We have signed a memorandum of agreement with the Philippine Council for Industry, Energy and Emerging Technology Research and Development (PCIEERD) for the conduct of passive seismic tomography to confirm our findings and refine the mapping structure of Mangosteen and Mabolo,' he said.
Forward algorithm is used to accurately determine the propagation path of seismic waves, which is a key link in seismic tomography. According to the ray travel path obtained by the ray travel time and the forward algorithm, the wave velocity distribution in the medium is reversed, which is called the inversion algorithm [187].
The large along-slope seismic tomography also crosses the fault (see lower parts of Figures 19(a) and 19(b)), but outside the location of geophones where the Vp variations are weakly controlled.

While other methods are already used to do this sort of seismic tomography, they rely on an artificial source to create the waves, while this natural method could be far more efficient.
