Well, i hope it happens ...
In the next 4 to 20 years, i'll still be around to read news of the event.
I'm reminded of a geology program i watched about the 4km long land fissure in Hawaii.
The geologist explained that the fissure is widening and when it eventually gives way, which it will, and sinks the 15,000+ ft to the ocean floor, it will have such force that a tidal wave 1000ft high will wash over Australia.
Rather gleefully he added that he hopes it happens in his lifetime.
Presumably from a safe place in the Northern Hemisphere.
