Yellowstone about to blow?

On january 27th cnn did a report on how yellowstone super volcano just "took a deep breath" It raised the ground by 10 inches. Now after the quake in japan yellowstone has shut down to the public and quit updating there websites. Is there something we need to know? Yellowstone supervolcano explodes every 600,000 years, we are at 600,040 years. The earth is making some huge changes right now...Is this a sign that this happens about every 600,000 years? Were just waiting for it all to happen?
