A major earthquake in Ibaraki prefecture in Japan? Tsunami, Aftershocks? What is the Great East Japan Earthquake!

It is said that an earthquake with a seismic intensity of less than 6 occurred in Ibaraki Prefecture on December 28, 2016.
I got up this morning and got to know. Although it seems to be the aftershock of the Great East Japan Earthquake, it is current information. Although it was good because there was no tsunami, I am worried about that there is a possibility that aftershocks may continue for the next week.
Even if the damage is not so great, if you feel this earthquake with your body you can not sleep with anxiety, you will never get negative, and various reminders will pass through your mind as you remember the big earthquake of the time .
Just the day before yesterday, my old gifts from Ibaraki living in Ibaraki were delicious and I requested another box with another. I thought about sending a noodle my friend liked, it was an incident just after I told that.
My friend safely survived the earthquake, but since it is uneasy, I sent a worried email to my friend promptly.
To be honest, I think that it is a relationship that can not be separated from earthquakes as long as it is in Japan.
It is proved by this year's Kumamoto earthquake that anywhere in Japan will get caught up in a big earthquake. In fact, in response to the Great East Japan Earthquake at that time, friends in the Kanto era made a U turn in a family round family Kumamoto. Because it was an event at that point, when I was worried and contacted my friend, it seemed that it was considerably worthwhile.
Although I should have avoided the earthquake, I also encountered a big earthquake.
Earthquakes are not other people's things, I feel that it is always an event that makes me realize that attention and preparation are necessary.
We hope that you will always be prepared and ready for unforeseen circumstances! It is!
I pray that you are safe for a long time!
