"I resented alimony."

The last legal form of indentured servitude.

The last legal form of indentured servitude.

Not quite, there's also the H1-B Visa.

I knew if we were diligent we could work immigration into this thread...

Working in this country under H1-B Visa is voluntary, in more ways than one, as has become painfully obvious by now.

Try not "volunteering" to pay alimony, though, lol.

No one held a gun to my head to get married in the first place.

You're right about that. The problem is with using the term "tsunami" to apply to the wave from an asteroid impact, as well as the wave resulting from an ocean floor earthquake. When I hear "tsunami", I immediately think of the wave that's gonna hit us after the "big one".

As the article, and other posters say, the wave from an asteroid starts off big. What we normally call a tsunami starts off as a barely perceptible ripple, which travels at hundreds of miles an hour through deep water. When it approaches shore, it's slowed down by the rising bottom & the water bunches up on itself. For instance, it can go from a speed of about 700 mph and amplitude of 1/4 inch to a speed of about 40 mph and amplitude of (say) 40 feet by the time it reaches shore.

If I'd thought about it, I would have realized that you were discussing the astroid-type wave -- the subject of the thread. Just when I figured out how to escape a "tsunami", out comes this latest doomsday scenario -- one I couldn't beat.

I saw the Simpson's episode on this. No Problem just stay out of bomb shelters. And I still got my manual can opener which was my y2k kit, I'm ready.

I'll just choose to believe that any near Earth object of sufficient size to cause such devastation has been discovered, catalogued and monitored, so we'd have at least enough warning to get out of harms way. Of course, this one wiped out the majority of species in existence at the time, so getting away from and surviving the immediate effects of the impact would be no guarantee. Sunlight would be thoroughly obscured for quite some time, agriculture would fail and winter would be something else for decades or longer. Just surviving would be quite an adventure, to put it mildly.

Instead of moaning and groaning about the challenge, what's YOUR solution?

My solution would be an effort to systematicly catalogue every object that crosses our orbit, with a program to consume every threat with robotic miners and factories. The impacts would never occur, and we get a bunch of cool stuff built in space.

The cataloging is already being done, of earth-orbit crossers, by Eugene Shoemacker's collegues. The challenge then is to make it economical with available technology, ie, make it worth someone's while(monetary incentive). Cleaning up space is a "nice" idea, so is cleaning up the litter on the street, but who does it for FREE? People have long thought of that, even hollywood in movies starring Bruce Willis, but be practical; going after asteroids to move them is not on the top of NASA's list right now, although they HAVE landed a probe on one already.

Twas thinking about it. I live at 3000' elevation, high in the mountains but at 20' above sea level you and hundreds of millions are GONE in a 300' high wave. What then would be a practical solution, something that you could do as a shelter to withstand 10 atmospheres of water pressure? A diving bell in the basement, an apollo capsule gumdrop, a thick-walled steel pipe, a ferro-concrete box or geodesic sphere...what? Since a 300' foot high wave will scour your city to bedrock, it has to withstand the bull-dozing effect from the debris, then pop to the surface with hull integrity still intact, then possibly survive for weeks in this vast floating sea of debris until it washes up on shore. Forget rescue, there won't be hardly anyone LEFT to rescue anyone else. TIDAL WAVE will be added to the Malthusian control mechanisms of war, disease, famine...since "moral prudence" didn't work very well. So, what is your design solution?

Before moving here, I lived most of my life above 1000' elevation. I used to wonder how anyone could live on the San Andreas fault. Now, I live in an area where we are all awaiting "the big one". Scenarios vary -- none of them are pleasant. At least I've learned how people live in such areas -- denial, fatalism, or a false sense of preparedness (store a week's drinking water, etc.), and just enjoy things while they last.

My glib solution "live on high ground" is partly fatalistic, and partly realistic. The government's earthquake emergency coordinator, when asked about preparing for a 100' tsunami, responded that he just bought a house at the 150' elevation. A woman who left the island once told me that she wasn't afraid of the earthquake, or the tsunami -- but she feared the post-apoloptic situation where no aid would come, and people would be starving, etc. Kind of like Katrina, only worse because Canada doesn't have the resources that the U.S. has, and being on an island would make logistics much, much more difficult. I thought that was paranoid at the time -- now, I'm not so sure.

The FEAR of the LORD is the beginning of wisdom. Figured out the Noah story long ago(15 cubits = 22' storm surge on the Indus River Delta)but the preparedness message is still the same. There are hurricane shelters spotted all along the US gulf coast, but there, with modern communications you don't get another Galveston 1900 where 6000 perished, people HAUL *** and get out of the way. Even with hours of warning the roads UPHILL will be jammed, so unless your car doubles as a surf board...So, "noah", you might want to troll around marine supply places, research facilities, to see what you could buy as some kind of cork/diving bell/pipe(something that can take 10 atm of pressure). As an architect I'd do a 8'I.D. geodesic dome/sphere 2 frequency icosahedron out of welded pipes/chicken wire mesh/ferro concrete w/extra conc in the floor(C.B. above C.G.). Sure people would laugh, they laughed at noah building a log raft out in his orchard....or you could be polite : your surplus diving bell stored in a storage shed. As a past dictator pointed out : the WINNERS get to write the history books...

plant a thermonuclear blast into a trouble maker.
Won't that cause Fragmentation rather than a Nudge?
Some fragments could be hugh and series.
...specially if some land on precautionary mountain-top cabins.
