Tru story, out of high school I did home improvment and subcontracting etc, and we got called out to this beutiful home with black garbage backs for windows
We met the owner who wanted to save a buck so he hired some illegal aliens to paint his home.
Well he didnt extinguish his gas pilots and the flamable gasses built up to the point of a perfect stoichiometric ratio of air to explosive vapors ( 18 to 1 ) give or take and BOOM.
It literally raised his cieling off the edges of his walls 6 inches, blew out every window and comprimised the structural integrity of his home.
I looked around, saw that load bearing supports wern't attached to anything anymore and slowly and carrfully backed out of there.
He had to start over from scratch.

In some ways yes and in some ways no but a meth explosion ? NO....No way unless there was a MASSIVE meth lab under those two homes.
I'm leaning towards a natural gas expolsion.
