The good old days. About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.

No. A tidal wave, or tsunami, has a small amplitude (wave height) and very, very large wavelength. If you were well offshore, you might not even notice it. If you were near the shore, it would be like the water just coming and coming and coming at you.
Would a submarine survive a tsunami?
Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.

How far inland would a 100 ft tsunami go?
Tsunamis can travel as far as 10 miles (16 km) inland, depending on the shape and slope of the shoreline. Hurricanes also drive the sea miles inward, putting people at risk. But even hurricane veterans may ignore orders to evacuate.

Can a cruise ship survive a tsunami?
