| Abstract: | It is studied that size of the area of region for calculating modulated small earthquake ratio using earthquake catalogue recorded by Gansu seismic network since 1988.Modulated small earthquake ratio is calculated respectively in five regions chosen in Gansu Province and its vicinity.Results show that an appliable minimum area is 6 square degree. |

| Keywords: | Gansu Modulated small earthquake ratio Area of anomaly region |
