Why is japan susceptible to earthquakes and tsunamis? explain using plate tectonics

  I believe that this is due to how Japan is near one of the plate boundaries or mid-ocean ridges, where it's easier for a tsunami (from the ridges) to accelerate its speed and for an earthquake (from the plate boundaries) to collide or interact in a myriad of ways. I know that this wasn't so specific, as you have to find the name of the ridge or plates involved in this type of action.

The sun's parallax would be 180 degrees, greater than which you can't get.  so a. would be your anwser
