As I said, I have seen this pattern before. And even if they have not said anything about it yet - there will be many casualties. In the incident I mentioned about 10 or so people died, in about 30 houses. It was even lucky that the school holidays had just begun, a number of families were not at home at the time.
I would assume that this Columbia Gas Company is done for, if they have to pay compensation far all this. So if you happen to own share of them...
