when is the first time tsunami hit any part of the world? Is there any record existing?

Answer 1

Not exactly sure, but to me, the most probable to be the FIRST KNOWN TSUNAMI is the one that hit Kamakura, Japan. I've seen the Great Budha in Kamakura. It's around 33 feet high. The history of the Great Budha is that it was enclosed in a building. The building was destroyed by a tsunami around 1,600 something, leaving only the statue. It remains in this state until today. What is amazing is that Kamakura is located inland from Tokyo bay by about 50-75 miles. It is also at an elevation of around 4000 ft (my estimate).

Oddly enough, I stumbled upon a program which talked about STRONG earthquakes in the US. They described a quake in the Seattle area which occurred a long time ago. It said that tree remnants from a strong quake probably occurred "around 1640". They determined the date by counting tree rings of the remnants, and said the quake was probably a magnitude 9.something. It went on to say that this was probably the quake that caused the tsunami that "caused widespread damage to Japan". It was certainly not the "first" tsu to hit, but was the first of so large a magnitude to cause scientific investigation.
