Heh, I did some work on a pretty cool tank monitoring hardware/software solution with a major fuel supplier here about a decade ago. They have facilities with about a dozen large vertical 40-80,000L above-ground fuel tanks for agricultural use. One of the features I was working on was leak detection, and we got the sensors and statistical analysis down to the point where, when testing with water, I could accurately detect the rate of evaporation from a smaller indoor tank. Anyway, we’re in an area that doesn’t have a whole lot of “acts of God” kind of destruction; no hurricanes or earthquakes, high winds occasionally but tornados are quite rare, etc. They reported to me that the number one cause of leaks on their above-ground tanks was bullet holes. Just… people randomly shooting at the tank farms. They don’t catch fire when this happens generally, they just spill out from the hole until someone catches it and transfers all of the fuel out of the tank.
