通过对1901~2000年云南地区5级以上地震记录完全性分析,发现20世纪早期云南地震漏载仍然严重,30年代以后5级以上地震记录较为完全,其中滇西南为地震记录的主要漏载地区。根据b值估算得到20世纪云南地区漏载5级地震143次、6级地震6.6次,这是地震活动性研究需要考虑的重要因素。60年代后地震活动的起伏与地震监控能力无关。

We analyze the completeness of the catalogue of M≥5.0 earthquakes in Yunnan from 1901 to 2000. We find that the records of historical seismic events in Yunnan in the early 20th Century are seriously omitted but relatively complete since the 1930s. The omission is the most serious in Southwest Yunnan. About 143 events with M≥5.0 and 6.6 events with M≥6.0 are omitted in the 20th Century in Yunnan based on the evaluation of b value. We suggest considering the completeness of the earthquake catalogue when studying the seismicity in Yunnan.
