In the year 2004 Indian Ocean experienced a earthquake on the 26th of December. This earthquake triggered a series of devastating tsunamis up to 30 meters high. The earthquake was one of the deadliest natural disasters in the recorded history. Tsunamis are more frequent in the Pacific Ocean than in any other oceans because of earthquakes in the "Ring of fire". Although the extreme western edges of the Ring of fire extends into the Indian Ocean. This tsunami  brought a lot of destruction to the people and the environment. Which of the following, if true, would weaken the conclusion about the effects of tsunami?
