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.

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.

'"even scuba divers further out were tossed around underwater for 15 minutes such that they were unable to control their movements."

Reports I have heard say those in deep water barely noticed it until after they had surfaced.

You simply climb up through the water when the turbulence stabilizes. You will be carried along with it and not have broken bones.
