The US Navy Map of Future Coastline? That one dates to 2012 if memory serves, but has been kicking around in various forms since the mid 1990s and has its roots in [this map.](https://dp.la/item/362e4bc9933aa4625f4d45fc27647524)  I would note that Scallion's original concept "doomsday" map was predicated on a bunch of catastrophes befalling us all prior to 2012 - believe the date was coincident with the Earth's impending "water death" attendant to the Mayan Calendar ending on 12/21/2012. So this concept has been around for nigh 30 years now. I believe the Navy's version takes into account massive tectonic activity associated with the Yellowstone caldera and a solar micronova. Don't remember if the events were concurrent or not though - perhaps the effects were additive? If a micronova, magnetic field reversal, rotational shift and attendant global tsunami were to occur, I'd expect the outcome to look a bit different with respect to Missouri. If I remember correctly the Navy's map shows the entire eastern half of Missouri being submerged while the western half remains dry. I'll call bullshit on that - at least in part - as the St. Francis Mountains of Southeast Missouri are composed of a granitic core dating to Precambrian time which extends well below the alluvial fan and unconsolidated sediments of the Mississippi embayment that overlie the New Madrid seismic zone. In short: They are the high point of the state, have a firm foundation and won't be going anywhere in a flood. So even if the worst case scenario of Doug Vogt's global tsunami occurs along with seismic activity, parts of eastern Missouri should remain - though it may be an Island. Of course there won't be many people left to inhabit it, but cleansing of the STL area wouldn't necessarily be a bad thing. So yeah, I've been looking at and studying this stuff for a long time. I picked up a minor in geology (my first love) along with an engineering degree, and have been looking at doomsday scenarios since they came to prominence after the 1989 San Francisco, 1994 Northridge and 1995 Kobe Japan earthquakes. Those events really shook up the engineering community, and doomsday scenarios and planning really became a thing thereafter. Edit: View that map link I provided, and expand and read the map description. They give even more detailed info on the "catastrophism" mindset that created it.
