I don't think we've seen the tail end of JP earthquakes... a 6.4M hit Sendai a couple of days ago.

Registered with UGS equivalent in JP and there are more eq activities in Northern JP.

Spoke to a good friend of mine that had geology interest, said that the tectonic plates are due for another major shift (the earth changing ones)

Really worried that I won't be able to visit that beautiful country.
