They don't. A tsunami is an ocean wave. For a tsunami to occur, it needs a huge fetch (distance) to run. To date, the only method of creating one is major shifts in the earth, particularly around faults.
The Earthquake occurred before the tsunami as it is what caused the tsunami.
It is impossible to predict when a tsunami will happen until it is triggered.

tsaumis happen because a big guy jumps into a pool
No, you would not be able to survive a tsunami in a pool. Tsunamis are large, powerful ocean waves that can cause widespread destruction and are not contained to the size of a pool.
If a tsunami hits a whirlpool, nothing noticeable will happen. If you have ever gone into a pool and circles it multiple times, it will make a whirlpool. Okay, so start making waves in a single direction. The waves will slow down the whirlpool, due to the friction on your "tsunami" water. So, just picture that on a much, much larger scale!
