The Gas utility shortly after the explosion shut off gas to the area, eliminating gas to 30 homes, IIRC. They inspected the gas lines outside the perimeter of the home that exploded and found no leaks.
Inside the home, as you said, there would be lots of leaks now as the gas pipe and fittings are scattered over a large area.
The home was not occupied at the time and had been unoccupied for a little while, where gas could accumulate inside with little chance to notice.
There is a claim the house had problems with the gas heat the week prior to the explosion.

Sure, but long before that, there were firefighters on the scene, and citizens there and you’d think they’d have smelled gas.
Maybe they did and our crack media teams haven’t interviewed any of them yet?
The house that exploded was occupied. The owners are the two people who died.
The house next door was unoccupied. It was also totally leveled.
I know this to be true because our very good friends live two houses down. Their house is most likely a total loss.
