Expanding Earth theory?
The sequence of huge earthquakes that struck off the coast of Sumatra in April may signal the creation of a new tectonic plate boundary. Scientists give the assessment in this week's Nature journal. They say their analysis of the tremors - the biggest was a magnitude 8.7 - suggests major changes are taking place on the ocean floor that will eventually split the Indo-Australian plate in two. It is not something that will happen soon; it could take millions of years. "This is a process that probably started eight to 10 million years ago, so you can imagine how much longer it will take until we get a classic boundary," said Matthias Delescluse from the Ecole Normale Superieure in Paris. Dr Delescluse is an author on one of three scholarly papers in Nature discussing the 11 April quakes.

So 1st they state that something SIGNIFICANT is happening RIGHT NOW.
It is not something that will happen soon; it could take millions of years. "This is a process that probably started eight to 10 million years ago, so you can imagine how much longer it will take until we get a classic boundary,
Then they contradict themselves and say it's a VERY GRADUAL process happening over many millions of years and not to hold our breaths ... nothing to see here, folks !
So, which assessment do we go with ... hmmm ?

In terms of how fast this could happen? .Look at the underwater cities that became submerged somehow and probably pretty quickly. The coast off Florida has ruins and evidence of intelligently laid out 'roads' and heck.

As for the poster who claimed they were contradicting themselves by claiming "significant", and then downplaying, um, I think your reading comprehension needs a little work. They said it's major changes, but they're going to take a LONG time to complete and form a new plate. It's still a very major change, just not a fast one. Sorry if it's not lickity split fast enough for you. Damn instant gratification generation *shrugs & meanders off*
In another new study, Fred Pollitz at the US Geological Survey in Menlo Park, California, and his colleagues found that the global rate of quakes with a magnitude of 5.5 or greater increased almost fivefold in the six days after 11 April - something that has never been seen before, even after very large earthquakes (Nature, DOI: 10.1038/nature11504).

The operative statement from above is "something that has never been seen before, even after very large earthquakes" which implies that on 11 April, a critical point may have been reached (and passed) that could unpredictably determine the rate at which further future splitting takes place.
Sure, could be another 10 million years or could just as likely be next year ... thats why Chaos Theory was invented. Additional small changes could result in massive unpredictable and unforeseen effects.
