I was surprised to hear about this explosion this morning, given that we only live a couple of miles away. There is enough intervening stuff (hills, water, buildings, etc.) to buffer the noise. That or we're both heavy enough sleepers to miss it.

My brother and his wife, who live less than a mile from the site, did not get our night of uninterrupted slumber. Based on the noise that woke them up, they thought a plane had gone down. No damage to person or property for them, which is good. In fact, the relative lack of serious injury is pretty amazing. So there's that to be thankful for, at least.
