How does Japan cope with earthquakes?
Many have a counterweight system installed that swings with the movement of the building to stabilize it. Smaller houses are built on flexible foundations that can absorb movement in 6 directions and diminish the effects of the quake. Elevators automatically shut down and have to be checked before they operate again.

How did Tohoku tsunami start?
The tsunami was triggered by the Tohoku earthquake which sent shockwaves through the water, travelling at around 650 km/h. When these waves entered shallower water closer to land, they slowed to about 50 km/h due to friction with the seabed. The waves continued to push together forming a larger wave.
