There was a nat. gas transmission line that blew in the northeast that
was directly *under* an apartment building and completely leveled it.


I've never seen a neighborhood distribution line bigger than 6-8 inches
or so.

The line appears to be a high pressure transmission line (~600 PSI I
believe), not a distribution line to service homes.

That was a natural gas major transmission line too close to the building
(s), not under it/them. There was 1 fatality, but the fault lay with
people digging there, and with inadequate inspection and maintenance. For
details see (on 1 line, with comma):
"http://en.wikipedia.org/wiki/Edison,_New_Jersey_natural_gas_explosion".

The lesson is that you should find out what is in the area where you want
to live before moving there.
