Abstract

  In our country, magnitude is determined by the length of existing active faults. The fracture width that can be detected by the gamma-ray survey is effective to understand the fault length. The type classification based on the fracture width as the active fault evaluation was shown by measuring the fracture width in various earthquake faults. The size of the geological faults is not specified. However, the classifying the source faults according to the length and width of the fracture is a technique of the technological evaluation in anti-earthquake procedures and seismic design.
