| 摘 要： | 总结了１９９３年１月２７日普洱６．３级地震前的地震活动特征和余震序列特征。发再震前一年，震中区及其所在的思茅、普洱地震带地震活动平衡，而与其相邻的耿马、澜沧震带地震活动增强，表现出与该地区往中强震之前不同的地震活动特点。余震序列各项参数则表现主余震型的典型特征。

| Abstract: | This papeer analyzes the characteristics of seismicity before the Pner earthquake with Ms6.3 on January 27 f 1993,and the afrershock sequence type.It is found that the seismic activity was quiet in the epicentral region and in its seismic belt,but increased in its neighboring seismic belt,one year before the Pner earthquake.There are different characteristics between the Pner earthquake and other moderately strong earthquakes occurred in this area before.The earthquake is a typical main shock--aftershock typerevealed by each parameter of the aftershock sequence. |
