Explosions over, in, China, wut? (Explosion of the Month club)

Again we go.

An explosion shook a chemical plant in the Chinese province of Zhejiang, state media said on Monday, though there were no immediate reports of casualties in a country on edge after blasts killed more than 160 people last month.

The blast caused a fire and thick smoke to bellow from the plant in Lishui city shortly before midnight, state radio said on its official Weibo microblog.

The latest incident in Lishui will likely raise more questions about safety standards in China, where industrial accidents are all too common following three decades of fast economic growth. A blast at an auto-parts factory killed 75 people a year ago.

Are we entering a news cycle called Chinese Explosion of the Month?
Better yet…why now?
