Cyprus and the Eratosthenes Tablemount (+Japan)

Esteemed Geologists,

I have a whole series of questions on Tectonic Plate migration, with the primary concerns being directed at the Island of Cyprus – and the surrounding area.

I will first begin with Japan, to lead into the questions on Cyprus.

Japan is an island, and is on the Eurasian Plate, right?

Japan is said to have moved 8 ft. during It’s recent tsunami/earthquake.

How does this happen? Are there minor plates within plates?

Is Japan's 8 ft. movement in addition to an average 2 cm. steady drift, usually associated with continents, or does this sudden movement actually indicate the norm of continental drift, and only the averages are assessed - over time?

I am also very interested in the Island of Cyprus, which is subject to subduction forces.

The Eratosthenes Tablemount (of Cyprus) seems to have been connected (at one time) to the Hecataeus Seamount. Is this a possibility?

What is the name of the plate bordering the African Plate and Eurasian Plate (west of the Indian-Australian Plate)? This plate seems to be what Israel, Syria, Iraq, and Saudi Arabia are located on.

Does the Cyprus Basin straddle two or three of the bordering plates, or is all of Cyprus (Island, H. Seamount, Basin, & E. Tablemount) all together on one plate?

Is it possible that the island of Cyprus (& H. Seamount) has moved North, over time - from the Eratosthenes Tablemount?

If so, what is the rate of movement?

Is it a certainty that the average rate of continental drift has been a steady constant - over centuries (& millennia)?

Can there not be other events, such as Japan's tsunami-based movement, which cannot be accounted for - within the averages of continental drift?

Is there such a thing as plate rotation, wherein two topographical points from different plates are more greatly affected than two other points (similarly related as the first two)?
