Modern petrol stations are designed with this very scenario in mind. The above-ground structure can burn down, but the underground gas tank will still be fine.
And more to the point, right now with galvanic isolation this scenario fails safe. The current won't go through the ground. In fact, you can peel away the insulation from the charger cable and touch one conductor while a fast DC charging session is in progress. You will be fine, as long as you don't touch the second conductor at the same time.
