Hi,
I have read you blog for a couple of weeks now. Since shortly after you started it, I believe. In any case I do enjoy it. I noticed that you listed some Natural gas explosions from the past. There was a large explosion of another sort in 1947 in Texas City, Texas. It was caused by a fire on a ship filled with Ammonium Nitrate fertilizer. It killed almost 600 people and pretty much leveled the town. It is an interesting story and shows just how devastating even accidents can be, let alone deliberate acts!
Thanks for keeping us all on our toes. – T.P
