I don't think there's ever been a Tsunami in Galveston Bay. Now hurricanes... Like another poster said, they're safer out there than closer in, and having them inside the actual Galveston bay would be incredibly dangerous due to congestion.

About 66 million years ago there was probably quite the Tsunami in Galveston Bay. Courtesy of the Chicxulub impactor.

But you might be right, I'm not really sure what the landmasses looked like so long ago. Also I don't think the place was actually named "Galveston Bay" at the time. :)
