I for one, am impressed by the study results. Thanks to Lead author Nathan Wood, a geographer for the U.S. Geological Survey in Portland, Oregon, and the rest of the study team we now have peer-reviewed scientific findings that bear out the validity of the old wives' tale supposition that walking faster than the tsunami tidal wave in order to get to ground higher than that wave will inundate the landmass will usually result in not being drowned by the tidal wave.
Without this scientific study people would remain conflicted about whether it was worth the effort to walk faster to safety and perhaps lose the equivalent of several person-months of sleep worrying about what to do should a tsunami tidal wave be coming. Now they can rest easy on that score and go back to obsessing over who will win the next round of America's Dancing With People Who Someone Without Any Taste Says Have Talent.
stay safe.
