Based on the theory of blown‐ups, as described by OuYang in 1995 and 1994, for nonlinear dynamic systems on general pansystems transformation, optimization and panderivatives, etc., in this paper, we employ the method, developed in OuYang (1994), to show that the blown‐ups of the nonlinear heat conductive equation is similar to the evolution of observable ground temperature “currents”. According to this analysis, we conduct a simulation based on the historical data of Tang Shan Earthquake in 1976. The simulation results show that: the blown‐ups of the ground temperature “currents” around the earthquake area can be applied to predict forthcoming earthquakes. As for the most disastrous Tang Shan Earthquake, the prediction time is about five months in advance. If the ground temperature “current” that embodies the earth’s crust movement satisfies the unintegrable panderivative equation, we can with enough information demonstrate blown‐up mechanism and forecast relevant earthquakes.
