Definitely going to happen someday - it's a question of when not if. The nature of the islands' porous volcanic rock makes them susceptible to this phenomenon.

Fun fact: Molokai's north cliffs are so tall because... they once were connected to an entire other half of the island that just sheared off from a massive earthquake and the resulting landslide. If you take a look at Google maps in the satellite imagery mode just north of the island, you can see the debris of the parts of land that slipped away into the depths.

What boggles my mind is that the Nu’uanu slide, when it took out half of the Ko'olau range, is suspected of having created the largest tsunami wave ever at 100m+ in height!
With great tropical beauty comes great geologic risk, I guess.
