The 2008 Yingjiang Earthquakes were a series of major earthquakes ranging from surface wave magnitude (M_s) 4.1 to 5.9 that struck Yingjiang County, Yunnan privince, China between August 19 (in UTC; August 20 local time) and September 3, 2008. It caused 5 deaths, 21 serious injuries, and RMB 2.7 billion in direct economic damage.

Earthquake Details

According to the China Earthquake Administration (CEA) and its subordinate [http://www.ceic.ac.cn/ China Earthquake Network Center] (CENC), a M_s 5.0 earthquake struck Yingjiang County, Yunnan province, China on August 20, 2008 at 05:35:09 China Standard Time (CST - 2135 UTC, August 19, 2008). A CEA report published on September 17 described two additional strong quakes of M_s 4.9 and M_s 5.9 in the same area the following day; CENC's data base, on the other hand, did not include the earthquake of M_s 4.9 at 20:20 CST on August 21 as the CEA report described, but reveals additional ones after the date.

Response, casualties, and intensities

According to CEA, these earthquakes caused 5 deaths and 21 serious injuries. Through [http://www.eqyn.com/ Yunnan Earthquake Administration] (YNEA), the provincial government invoked Level IV emergence response protocol in the relief. Affected people amounted to 209,605, roughly 2/3 of the total population in affected areas. Direct financial damages amounted to RMB 1.3 billion. In addition to building damages, the heaviest infrastructure damages occurred to water resources facilities.

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 (Heavily damaging) on EMS-94 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.
