To the first question: no.

Second: I don't know because I don't live there.

Third: The intensity of an earthquake from the
epicenter seems to fall off as a function of
distance (It is probably something approaching
1/r^2, but I don't know the exact drop-off rate).
We felt the quake in Nigata prefecture
here in the Tokyo area (about 200 km away), but
it already had lost most of its intensity so it was
little more than a little shaking around. So even
_direct_ influence on the other side of the world is
so unlikely, that I think you'd might as well
consider it impossible. At any rate, the influence
must run from the stronger quake to the weaker one
if it could ever happen at all.

It was interesting that several earthquakes occurred
in a relately short time span (in geological time scales).
Usually, there is just one shaking, about ten minutes
latter, I think it was an aftershock, but the intensity
didn't drop off all that much. A half hour later, I'm
sure that was not an aftershock. That is the very first
time I've experienced anything like that and it was a
bit nerve wracking.
