From a geophysicist, let me put your mind at ease.
Japan is on a subducting plate boundary. As is new Zealand. That's what creates volcanoes and the most intense earthquakes. I wish I could draw you a little diagram.
I study the volcanic impacts on tsunamis across the pacific. I measure sedimentary ocean cores and determine the frequency of earthquake/volcano induced tsunamis. It happens very regularly. No increase as of late =)
IIN normal that all these earthquakes and tsunami are occuring??
