Tsunami waves are almost the same as ripples caused by throwing a rock into a pond. what is the major difference between the two?

Given that Tsunami waves are almost the same as ripples since they both caused by throwing a rock into the pond, the major difference between the two is that the energy source of tsunami waves is much greater compared to ripples. Ripples are just transverse waves. Hope this answers your question.

Tsunami waves are compression waves, ripples are transverse waves
