A continent lost underwater?

So I've been trying to create a world and I've been planning on the continents being drowned out almost completely in water from a terrible tsunami, storm, earthquake or an act of one the gods or something, maybe a mixture even.

The land before would have very deep valleys and would be close to sea level to begin with, so maybe some of the land would still be above water, but most of the continent would be underwater, and wipe out a good portion of its citizens.

More specifically I suppose,

• What would be a more plausible reason (if the ones listed aren't too good) to lose a continent in a way it wipes out most of its population?
• Would there be survivors if they were able to board ships in time to sail over to another continent in time?

I've read up on Mu and Lemuria as presumed lost continents but it doesn't exactly answer my questions.
