You can get the gas out of those underground tanks at a gas station without much effort. But even if they couldn't, they could still distribute directly from tankers. They did that during Katrina for the relief effort trucks, and they may have even done it during your earthquake. Just because you haven't personally seen them do such things in disaster scenarios so far doesn't mean it hasn't happened, or that it couldn't be done sometime in the future.I don't know about India but in the US gas pumps (and diesel) run on electricity. No electricity, no fuel. We were several days in Kalifornia after the last big earthquake before many of the gas stations were opened.
There are all kinds of doomsday scenarios floating around out there, all of them with at least some followers who are convinced they are about to happen tomorrow.Why are those odds high. More blanket statements. How did u calculate these odds? What sources and references. Shouldn't u say, "I have a feeling this will happen"
