Actually, when LNG goes back to a gas it expands to several hundred times its liquid volume.
In Cleveland in the 40's an East Ohio Gas storage terminal sprung a leak and the resuling explosion destroyed over 100 square blocks, burned down over 1,000 houses on the east side, and melted over 60 cars.
It can also travel miles through the air before reaching the inevitable spark. A pretty good thriller by Basil Jackson titled "The Night Manhattan Burned" is a page -turner, hehehe.
Not a fair comparison to todays technical advancements in storage and safety. Like comparing pictures of the old San Francisco earthquake and subsequent fires that destroyed the city, to today's rebuild of the city with new fire, safety, and construction codes.
I am confident that if you'd analyze the codes such a facility would have to be built with safety concerns would not be as much of an issue.
But just scaring people will stop anything new from taking place.....airplanes, high speed rail, cruise ships with huge numbers of passengers.....and on and on.
