Observations

• I tested this experiment 45 times.
• During each exercise, the tsunami-like wave that was created by the lowering of the weight in the water tank would naturally cause some of the water in the tank to overflow. With each test, the level of the water in the tank became lower, causing the depth of the water to become gradually shallower. I noticed that, as the water became shallower, the wave became clearer. 
• When the bag of gravel was lowered down the inclined slope into the tank filled with water, I noticed that the crest of the first wave curled over much like a real tsunami. The water sloshed back and forth after the first wave hit the impact slope. This observation is very typical of what happens when real tsunamis occur. Real tsunamis slosh back and forth in harbors (edge waves) causing the tsunami danger to continue after the first wave hits. 
• The first wave generated by the simulated  landslide crested and caused flooding at the runup end of the tank, washing away away the model trees and buildings.

Below are some pictures of my experiment when I tested it.
