Odd they claim a gas pipeline when the fuel is liquid ...
Gas line burns are a long, high pressure jet of flame coming out horizontally, with a larger area-sized explosion first as the fuel-air mixture blows up.
This is more likely a pressurized liquid.
I would think that depends on the pressure of the line.
There’s also petroleum pipelines (gas, jet fuel, etc.).
Whatever the fuel, the flames are at least a couple of hundred feet high not “60 feet”.
Just reported as a 24” gas line per PG&E.
