There is still no sign of a full meltdown of one of the cores. So it is reasonably to believe that the way these reactors are build is strong enough to survive a tsunami and an earthquake.
But, if a core collapses in one of the following days then there is a reason to take a good look at the position of these reactors. For instance in Holland we don’t know any earthquakes and tsunamis, so you can say that a reactor here is safe enough.
