Now to understand the problem and what will be relevant in press reports. A gas system distributes gas at high pressures. At multiple points, regulators repeatedly reduce pressure until gas into a house is maybe 3 PSI. Apparently a high pressure surge started in Ohio. Then travels across three states. Somehow this pressure wave may have blown through layers of regulators.
Also are many pressure relief valves including one maybe at each consumer's gas meter. How did all this fail? A resulting investigation should be informative.
