| Abstract: | On the basis of the temporal and spatial distribution of seismicity and changes ofseismometry parameters, the characteristics of seismic activity before Cangshanearthquake are analysed in this paper. The results indicate that there are anomalies ofthe seismicity pattern and several medium - and short-term seismometrical parametersoccurred before Cangshan earthquake with M=5.2, but there is not any short-termand impending information of the foreshock activity. |
