- Abstract:
-
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.
