Tsunamis are large water waves, typically generated by seismic activity. basically, its like a big huge wall of water. though there are tornadoes formed from water, there called waterspouts, i believe.
I was so pissed off because there was a really nice tsunami here when I was visiting in Oregon and so I missed it! It was so disappointing. I also missed a big earthquake. I just miss everything.
Lol, I live in Oklahoma, which is like tornado party central. And I have a friend from NYC and the first test they did after she moved here she was in my house and she screamed and grabbed one of my blankets and ran into the basement. I had to stop laughing and go tell her it was just a test.
