| Abstract: | Base on the definition of active fault and its meaning to engineers, this paper reviews some geological aspects and problems, such as the application of dating results in determination of active faulting ages, seismo-tectonics background studying on moderate-strong earthquakes, estimating earthquake recurrence from geological investigation, and probabilistic evaluation of the ground offset of active fault. |

| Keywords: | Earthquake safety evaluation Fault activity Seismogenic structures The annual average rate of earthquake recurrence |
