The disturbance moves outwards. The central point just oscillates until it's damped out by friction. As it oscillates the disturbance propagates outwards.
"will both activities generate a tsunami..and the same type
Yes. If the wave moves a bunch of wavelengths, they both look the same. Close to the initital disturbance, it depends on how the oscillation starts.
Does this mean beach front real estate prices will decrease?

Can You Make that Bigger Please ?
LOL!!!!!!!!!!!!!
The scenairo they are talking about has nothing to do with plate movement. The cause is half of a mountain (volcano)sliding into the ocean.
Drop a large rock into some deep water - same effect.
The bad news is - there is another one waiting to go off in the Pacific. The Big Island of Hawaii. Do some research on the "Great Rift" on that island. Huge hunk of the island sliding into the ocean.
The really bad news is that it is aimed at California. They were doing a geologic survey off the coast a few years back and found evidence that it has "fallen off" before. The slide went miles out. The calculations for the height of the wave created by that was mind boggling - 800 - 1000 ft., if I remember right.
So, when you play tourist - keep your jumping up and down to a minimum, ok?

I'm sorry, but I can't quite make out the pic you posted. Could you please enlarge it? TIA!

If recent history is any example, look at Florida being smashed with one Hurricane after the another during the 2004 season with even loss of life, yet, people will still pay incredible prices to live on either coastline.
That map was on a LARGE size.
Yes, I think it was called the USS Bouron Liver.
