some gas supply lines got ripped loose in the blast. Whether the house blew
up from a gas leak or a pile of TNT, there *WILL* be a gas leak now.
A lot of the gas delivery infrastructure is getting very old. Shortcuts
that may have been taken during the original installation of the pipe are
now beginning to result in failures, some pretty horrific.
<<In January 2011, federal investigators reported that they found numerous
defective welds in the pipeline. The thickness of the pipe varied, and some
welds did not penetrate the pipes completely. As PG&E increased the pressure
in the pipes to meet growing energy demand, the defective welds were further
weakened until their failure. As the pipeline was installed in 1956, modern
testing methods such as X-rays were not available to detect the problem at
that time . . .
On January 13, 2012, an independent audit from the State of California
issued a report stating that PG&E had illegally diverted over $100 million
from a fund used for safety operations, and instead used it for executive
compensation and bonuses.>>
Lots of people don't know they are living very close to 30" high pressure
gas mains that may be over 50 years old.
I sense that dpb hasn't seen the picture. With the houses exploded, the gas
company isn't likely to know what's a new leak, or a previous leak.

Use a sniffer---the piping has to still be there. Of course, if it's a

I'm sure if folks will just calm down and let the forensics folks do
their thing they'll find the root cause...

That's legalese for "We are denying responsibility early." (-:
That certainly makes sense, with most homeowners being well-equipped to deal
with gas-related issues. NOT.
A few years ago, security cameras captured a live gas explosion at a nearby
shopping center. The explosion here was consistent with the enormous amount
of damage that explosion caused. Oddly enough, the intensity (at least
compared to TNT) was low enough to cause massive property damage but not any
serious injury to people.
