Bizarre glowing cloud phenomenon in the sky was observed about 10 mins before the May 12, 2008 Sichuan earthquake took place. This was recorded in Meixian, Shaanxi province ~550km northeast of epicenter. The phenomenon was said to last for about 1 min. source: http://v.youku.com/v_show/id_cb00XMjczNTczNDA=.html A map showing two locations where such clouds were sighted relative to Sichuan earthquake epicenters: http://img223.imageshack.us/img223/2453/ecjm1.jpg See similar clouds appeared ~200km west of this location: http://www.youtube.com/watch?v=KKMTSDzU1Z4 More photos (reported taken 1 hr before the quake): http://shenyun.epochtimes.com/b5/8/5/14/n2116538.htm These clouds seemed to be glowing or somewhat luminous and seemed to resemble some characteristics of the Auroras. I am not sure exactly what they were or whether they indeed had anything to do with the quake. I am no expert anyways. See if any scientists are willing to give a full explanation. If such phenomenon can be proved for its connection with earthquake occurrences, maybe they could be used as warning signs and would be life saving. If not, just learn these clouds as yet another rare atmospheric phenomenon and no need to panic when seeing them. After all, this might well be just a rare atmospheric phenomenon occurred by coincidence. Though, just wondering if there's any possibility the formation of such rare clouds be catalyzed by any event??
