Tokyo Earthquake 3/14/2010 has been felt in Tokyo, not centered in Tokyo as many would presume based on titles "Tokyo Earthquake" Please read more (march 14, 2010)
Earthquake of magnitude 6.6 has been reported 3/14/2010. Research shows that, since earthquakes are random and fractal, earthquakes are difficult to predict. However, a major earthquake that could cost millions of lives, can be expected near Tokyo every 400 years.
Tokyo earthquake prevention consists of several advances in earthquake damage prevention. Just like the cruiseships have massive weights preventing the ocean waves to be felt in the ship, the tallest buildings in Tokyo have massive systems of springs and weights underground to absorb the major part of the energy destined to hit the building.
Despite these devices, an earthquake of magnitude 7, would cause major damage.
Tokyo sits on the intersection of three massive land plates, the Philippines plate, the North American plate and the Eurasian plate, and people are accustomed to feeling a Tokyo earthquake daily.
[Update] A recent news from Reuters reports that the earthquake was centered offshore, not directly in Tokyo:
