Tsunami is the result of an earthquake that arises under the sea.

This statement is correct. Tsunamis are often caused by underwater earthquakes that lead to the displacement of a large volume of water.

Most of the tsunamis occur in the Pacific Ocean.

This statement is correct. While the Pacific Ocean is known for having a high frequency of tsunamis

As a tsunami approaches the shoreline, the bottom of the waves move faster than their top do.

This statement is incorrect. In a tsunami, the entire water column, from the ocean floor to the water surface, is affected. As the tsunami reaches shallower waters near the shore, the wave's speed decreases, and the wave height increases, leading to the characteristic "run-up" of the tsunami.

Therefore, the correct code is 1 only.
