I heard of this guy once who bought up a bunch of land in Arizona and Nevada in advance of a potential quake.
He had big development plans. Part of which depended on the land being ocean front property in the future.
He had planned to split apart the San Andreas fault-line using Nuclear armaments – the resulting explosion destined to send the entire Californian coastline and its inhabitants to murky ocean depths.
The problem is that these California inhabitants were likely the most lucrative of future customers. Once his accountant ran the numbers he had to save face, so he told his assistant to release Superman at the last possible moment to allow him to save California and foil the plan.
… Or something like that.
I think your best bet is to invest in Kryptonite futures.
