同时用几种地震方法对该地区的地下结构进行了调查，微地震观测、共深度点（CDP）剖面法和伪反射剖面法（PRP）。在第一阶段的调查中，可能的地下结构的不连续性检测沿两个线性阵列上的平面上的微震观测，并在西部和东部的平坦的基岩深度的差异进行了粗略的估计。在第二阶段，用CDP方法勘测了平地的两个小部分，以便更详细地确定地下结构。此外，PRP方法被调用来补充CDP剖面法的覆盖范围。
The subsurface structure of the region has been surveyed with several seismic methods simultaneously, i.e., observations of microseisms, the Common Depth Point (CDP) profiling method and the Pseudo-Reflection Profiling (PRP) method. In the first stage of the survey, a probable discontinuity of subsurface structure is detected from observations of microseisms along two linear arrays on the flat, and the difference in the basement rock depth on the western and eastern parts of the flat is roughly estimated. In the second stage, two small portions of the flat are surveyed with the CDP method in order to determine subsurface structure in more detail. Moreover, the PRP method is invoked to supplement the coverage of CDP profiling method.
