Just a couple of points of order:

The centre of the earth is not a fusion reaction. It's probably mainly molten iron and nickel and possibly some oxygen. But it's far too cold to be a fusion reaction.

Yes the sun is one great big fusion reaction. But a) the sun is approximately 150 million kilometres away from us. b) nuclear fusion is a relatively 'clean' reaction and c) we can't do it on a commercially viable scale at the moment. The last time i had a good read on nuclear fusion reactions we'd only sustained one for fractions of a second.

What's happening in Japan is a possible catastrophic fission event.

Whether nuclear fission is really a viable power source is open to massive debate.

What austrian airlines is probably doing is a PR excercise to reassure their passengers.
