There is a way to survive these things. It's not by standing around gawking. You must hyperventilate your lungs and take a deep breath and dive directly underneath the wave, staying as close to the bottom as possible. After the energy passes above, you can swim up.

After the energy passes above ...

The energy never "passed". Watch some videos to see (link in post#109).

You're kidding right, this wave was moving like a train and lasted for 20 minutes, flowing inland miles with such force that cars, trucks and even bull dozers were miles inland, these folks surely didn't survive, even scuba divers further out were tossed around underwater for 15 minutes such that they were unable to control their movements.

You should write a book.
