This does nothing to qualm my fears that the Chinese have been working to make a bio-weapon based on pneumonic plague - in fact, far from it! Bio Labs are often secretly located in remote areas and China could not have anticipated the high level of earthquake activity which, not being a pun, has plagued the area. Furthermore, as I pointed out, the residents of this area are mostly Tibetans - a segment of the "New China" that dislike the fiercely independent Tibetans. Tibet was the home of the Dali Lama and was taken by force in China's drive to implement their "One China Policy."
I still believe these outbreaks of pneumonic plague were engineered in Chinese Bio Labs, and although their accidental release due to a barrage seismic activity may have been the culprit for the release of the pathogen - nobody knows if these newest outbreaks are from past earthquakes or or tests of their Bio Labs being conducted on a population that China still refuses to respect their heritage and customs. China has been bitterly criticized for building manufacturing facilities and dams in the area because of its known seismic activity - and were warned before it happened, but China has a mindset of its own, and human life in China always has been cheap if not at times an actual commodity when they executed prisoners to farm their organs for their transplant program for foreigners that had the money for the necessary surgeries.
Another Note: In hindsight, a release of this pathogen because of an earthquake doesn't make sense, because if it was released during one of the larger quakes, it seems that we should have seen massive deaths at that time. It's almost a double-edged sword; I also remember that the Chinese wouldn't let anyone into certain areas - and so far, no explanation has been given for that, so they may have been attempting to contain any release from a clandestine Bio Lab at that time. You almost have to toss a quarter to figure this one out due to the secrecy that surrounded some areas where the quake occurred which the United States stated were areas suspected of doing nuclear and other research that was potentially extremely dangerous.
