Texas plant explosion

First it was Boston, and now Texas. The injuries I read just gets more gruesome. Death toll on the rise too.

Whats worrying? Both incidents were not caused by natural disasters..

I watched the video of the explosion and it was massive : http://www.dailymail.co.uk/news/article-2310825/West-Texas-fertilizer-plant-explosion-leaves-dead-100-injured.html
