Title: Analysis on Energy Field of the Seismic Activity in Earthquake Hazard Area from the Northwest to the South of Yunnan
Abstract: According to the Random Function Theory,we take the seismic energy field from the northwest to the south of Yunnan as a spatial-temporal random function,and study the isogram chart of the time weight coefficient of several typical sub-fields,spatial contour,and distribution of the average energy field by the expansion of natural orthogonal function.We find that the curve's sharp rise and fall suggests the occurrence time of the strong earthquakes,while the high-value anomaly of the spatial contour suggests the risk zone of the strong earthquakes.
