"The scientists used data from the Envisat satellite to show that an 8-metre rift developed along a 37-mile (60km) stretch of the fault in just three weeks."

I remember a National Geographic special that talked about the fact that salt water was beginning to trickle into the upper end (about 20 km inland, I recall) of the Great Rift valley. One or two good quakes and the red sea could start to drain into the valley. Could happen in our lifetime.
(Good thing too, with all the water coming from the Al Gore's melting ice caps...now we have somewhere to put it! )

Or one or two nuclear warheads
