FEMA has hazard maps for Hawaii and other areas where the hazard exist. Hawaii requires design for tsunami waves.

Subject: tsunami 2...

You are right, as a tsunami is more or less caused by a singular earth rattling event, it does not have a "period" so much as a very, very large wavelength. (Right? This is the right term?)
What I am meaning is, unlike a normal wave with a 8-15 second period (or whatever), a tsunami likely has a very LARGE wavelength, and thus acts as a large mass of water, not something that could curl and break on a reef like a normal wave....   SO, even though places like Maui or Oahu have outer breaks that can handle 30ft+ waves, a tsunami wave would be much different due to the width of the wave.....
Again, if anyone knows of an organization where they need SEs to go and review the damage, let me know.....
