A: Hey, did you catch the news?
B: Nope, what's up?

A: There was a big earthquake off northern Japan! This guy named Suppasri Anawat, who's an expert in tsunami stuff, said the highest wave hit a place called Kuji Port.

B: When was this?

A: It happened on Monday. He also said that the wave was 70 centimeters high and arrived at the port as the fifth wave around one and a half hours later after the first wave reached the site.

B: That's scary! What did he say about why it wasn't worse?

A: He said the waves came when the tide was low, but if they had hit at high tide, there could have been more damage. So, he's advising people not to let their guard down even if the first wave is small and stay in safe places until all warnings are lifted.
