A tsunami could actually scour out so much of the ground around the building that it could be destabilized and fall over. Diversionary walls and berms could reduce this risk. There isn't a single magic formula, Deierlein said; instead, buildings have to be treated on a case-by-case basis.

And NO, YOU CAN'T OUTRUN A TSUNAMI.
It's just not possible. It doesn't really matter how fast the wave is coming in, the point is that once you get a sign of a possible tsunami, you really shouldn't be near the wave in the first place. Know the warning signals. Don't ignore them or underestimate the speed of the wave.

Should a tsunami occur and you cannot get to higher ground, stay inside where you are protected from the water. It's best to be on the landward side of the house, away from windows. Often tsunamis occur in multiple waves that can occur minutes apart, but also as much as one hour apart.
How far can a tsunami travel uphill?
When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. However, tsunamis can surge up to 10 miles inland. “It's really just kind of relentless, the water just keeps on coming and coming and coming for a long time,” Garrison-Laney says.

Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor.

Anticipate slowdowns caused by traffic gridlock and hundreds of other boaters heading out to sea.
