Gas lines don't spark and explode here and there and over there nilly-willy all at the same time,it just doesn't happen.

They said it was over pressure form the main line? Sounds like someone hacked into the system that controls the pressure....That's a lot of pressure and I'm sure there are 15 levels of safety that doesn't  allow to over pressure the system.

The problem with that is that there are multiple levels of safety built into the system that are automatic. They are not controlled by the gas provider. If they detect more pressure or less pressure than should be in the line within a range of 'acceptable' they start shutting things off. The provider has to go and manually reset the system at each zone in order to restore the flow of gas. If there was an over pressure situation, that zone would have cut off the flow to prevent just this sort of thing. This is a gas company/contractor issue at this point. IMO someone cheaped out on parts and routine maintenance.

As far as jumping willy nilly, not everyone on a block will have gas heat/stoves. Many of the houses still have oil and coal heaters and cook with electric ranges. Others are all electric with an oil backup. It could be the map accurately shows the customers on that particular line starting with the one to the south, hitting the big disaster zone where customers are clustered and then jumping to the outliers to the west.

I'd say gas theft.
They bypass meters and such.

Dallas issues..which were bad gas line design and improper materials.

North Attleboro man guilty of natural gas theft and meter tampering in Attleboro, elsewhere
The investigation determined that from 2008 to 2012, Bankert, a formerly licensed electrician, tampered with 10 gas meters at six laundromats he owned in Attleboro, Brockton, Lawrence and Worcester for the purpose of stealing natural gas.

They are using new plastic gas lines which are prone to more leaks and sooner than black pipe.

As a natural gas line installer with an HVAC company in the 90's, we used to pressure test our installs to maintain 30 psi for 30 minutes. Post installation inspections on all installs by building code inspectors.

Just reading a bldg codes page where it looks like 5 psi is their standard now.

My opinion that seems to echo yours, is that somehow there was an over-pressurization in the main feeding these areas. The weakest links will fail first, and the fires/explosions will start where there is an immediate flame or spark source nearby.

How multiple safety features failed on the main will be an interesting discovery.

Firefighters going to have a long day.
