Figure 5. Location of surficial gas and the two dominant faults. The surface topography is relatively flat in the area with an elevation of roughly 200 to 208 m. The contour lines represent the elevation of the top of the surficial gas. The seismic lines provide spatial relation to . The dashed black box highlights the area where low Vsh values are vertically aligned (See )
