Yeah, you're tight. According to my reading, tidal waves are only centimeters or inches high in the open deep ocean but increase in height as the depth of the sea greatly decreases, as you said.  Regardless of the location, tidal-wave surfing could only be done in the shallows of the sea, on the shoals

 

I can't find anything online to confirm what I recall, but I seem to remember something on British tv from years ago.  A pair of surfers were forced to ride out the tsunami generated by the Chilean quake of 2010.

They were surfing normal waves when the tsunami came upon them.  The main problem they had wasn't its height or speed but its unpredictability.  I recall them mentioning the turbulence, which, through a combination of luck and skill, they managed to ride out unharmed.

 

Is my memory playing me false or can somebody find something to verify this?  Just curious.

 

Thanks.

Tidal waves are commonly considered as being synonymous with tsunami, which is cool, but technically they are different

Big tsunami waves happen in the shoals, the shallow parts of the ocean near the shores or somewhere out in the shallows of the ocean. So what you explained could have happened. The explanations of a tsunami are like this: a moving displacement of water volume, which defines a tsunami, can happen in at least 2 different ways. The most common would be an Earthquake involving a readjustment in the height of the ocean sea floor, one part moving up relative to the other part. This results in a tsunami wave moving in the direction of the lower plate. The other type is where a land mass suddenly cleaves off into the ocean causing it to rise as a tsunami. This is what could happen involving the island of La Palma.

 

This link suggests that the resulting tsunami from La Palma may not be that big based upon the most likely cleaving considered.

Yeah that happened. I remember the story. It was minor enough to where they were able to ride it out. It made mention in the surfing community.

Yeah, so many factors to consider. The 2001 study seems more like hype than anything else. That's the older study that sparked the TV programs I saw years ago. With the 80' surge being worst case scenario, but very unlikely. In any event, I've alerted by family on the coast to keep an eye on the news and watch the volcano with an evacuation plan in mind because of the 8 hr window to evacuate if necessary.

I've been watching this for days.  We're right in line for it if it blows and causes a tsunami. I already have my place to escape. Its one hour from my place. Goodbye to all. Remember that I loved you. 

 

Seriously, this is very interesting. I've been following natural disasters for awhile now. I am fascinated with all of it (nature) but of course, I hate it and feel very sad when people die such horrible deaths.

 

This will be interesting to see how this volcano behaves in the next few weeks, months. 

 

Here's a link that might appeal to you, Margee.

Not just the disastrous stuff either.

 

It's all fascinating.

 

Enjoy!

 

Thank you.

Update.

 

A magnitude 5 earthquake has shaken La Palma today.

Thank you.
