Almost every night now we wake up by one or a few after-quakes. This night was no exception. We had two at 5:02 and 5:09 in the morning. Just outside Tokyo, but not more than 3 in magnitude. Still enough to wake us up.
Looking at JMA’s earthquake information it seems there were quite a few after-quakes along the whole nort-east coastline. All in the same magnitude as the two outside Tokyo around 5 am.
