| Abstract: | A great many of micro earthquake activities have been recorded in the neighborhood of Three Gorges after reservoir impounding since 2003. Frequency spectrum of 36 known seismic events are firstly calculated, and then the characteristics of frequency spectrum parameters are concluded. After contrasting them with seismic events on the Three Gorges area, the results show that there are comparatively abundant low frequency, and lower dominant frequency, peak frequency and corner frequency by comparing them with tectonic earthquakes. According to the characteristics of these frequency spectrum, 29 seismic events on the Three Gorges area are classified to four types: tectonic, surface tectonic, event between tectonic and collapse, and collapse. |
