Did you notice anything strange around the time of the Japanese earthquake?

I don't want to sound rude by saying the notion of your friends' psychic powers is nonsense, however, and this is only my opinion, I do believe that if what you might call psychic power were to exist, it's far more likely that it would be attributable to some latent perception inherent in our physiological person that is very very rarely needed.

I'd consider it quite plausible that, like horses running for higher ground hours or days before a major natural catastrophe, or birds or fish fleeing in similar fashion from an imminent major natural event, that humans too have some basic perception of global or hugely significant environmental and natural events.

Now I understand that this is probably along the lines of what you were getting at anyway, but phrasing your suggestion in the way you did likens it to levitation, or moving objects with ones mind. Suggesting that they experienced a common sensation on the basis that they are brothers fails to give due regard to the fact that on Friday, the worlds axis tilted permanently by (I don't have the exact figures to hand - and I'm not going looking for them now, you can check on the internet if you want) something like 0.8 degrees. As a consequence of the earthquake, Friday got shorter by 0.14 seconds.

Something that can affect our planets alignment and rotation should send shivers up your spine. If a seismograph in Ireland can detect it, then the sensation is perceptible through your legs. Some people mightn't even notice, some people probably would. In the example of horses I gave, it is most likely the case that one or two horses feel/perceive the oncoming danger, when they bolt - the rest follow.
