According to characteristic of geologic structure and seismic activity in I.iaoning and the neighboring area, based on the earthquake cases studies and prediction works, the warning criterions of moderate-strong earthquake in the southern Liaoning province and the Liaoning--Inner Mongolia boundary region are extracted, and the earthquake early-warning model based on timescales is constructed. All kind of indicators used in early-warning model are processed with nondimensional method by the analytic hierarchy process. The relative order of importance and weighs of each indicator are calculated. Finally, the early-warning level of moderate-strong earthquakes in Liaoning area are obtained by judgment matrix and mathematical method for matrix operation.
