Legs Weaver #77 (2002) page 58: Yep, here's the tsunami

In a story called "Tsunami!", obviously there's going to be a tidal wave at some point, and here it is, striking the floating hotel and then the beachside village.

“While that colossus was submerging, the wave continued its journey of destruction towards the island of Honoi and its helpless inhabitants! It all lasted a few moments... then there was only silence!”

The beachfront appears to be full of ten story buildings, so this quite a populated island paradise. The tsunami towers over them all. A real tsunami is typically around 100 feet tall, but the highest ever recorded was 1,700 feet. Hard to imagine.
