A CEA report published on September 17 described two additional strong quakes of Ms 4.9 and Ms 5.9 in the same area the following day; CENC's data base, on the other hand, did not include the earthquake of Ms 4.9 at 20:20 CST on August 21 as the CEA report described, but reveals additional ones after the date. | access-date=2008-09-20 | archive-url= https://web.archive.org/web/20081103042223/http://www.ceic.ac.cn/| archive-date= 3 November 2008 | url-status= live}}

Impact

Casualties

According to CEA, these earthquakes caused 5 deaths and 21 others were seriously hurt, as well as 109 minor injuries. Through the Yunnan Earthquake Administration (YNEA), the provincial government invoked Level IV emergence response protocol in the relief. The number of affected people is said to be around 210,000, roughly 2/3 of the total population in the affected areas. Direct financial damage amounted to RMB 1.3 billion. In addition to building damage, the heaviest infrastructure damage occurred to water resources facilities.

Intensity

On the seismic intensity map published by CEA, maximum intensity of these earthquakes reached liedu VIII on China seismic intensity scale (CSIS), which is somewhat equivalent to VIII (Severe) on the MMI and from which CSIS drew reference. Liedu-VIII zone spans 26 km2 near the epicenter. Total area of liedu VI (Slightly damaging) and above is a north–south oval of 4,511 km2.
