NHK is showing a few surveillance camera shots where the camera is obviously shaking (not sure where they were taken, though, because my Japanese comprehension is not that good). The shots that they showed did not look particularly severe (people at a crosswalk apparently do not have difficulty walking, standing, or running), but maybe those images are from a hundred miles away. They are now showing shots of what looks like damage to a highway tunnel, damage to the face of a building (large vertical sign fell off), ceiling collapse in what looks like a workshop or small factory of some sort, etc. which may be from Niigata.
Powerful quake hits Honshu
A powerful earthquake hit the main island of Honshu just before 6:00 p.m. on Saturday.
According to the Meteorological Agency, the focus of the quake was 20 kilometers below the surface of central Niigata prefecture, 250 kilometers north of Tokyo.
The quake had a magnitude of 6.8.
It was most heavily felt in the Koshin and Kanto regions.
The Japanese scale intensity of the quake was six-plus in Ojiya City, six-minus in Nagaoka City, five-minus in Kuki City, and four in Tokyo.
Two after-quakes, each with a Japanese intensity of over six followed within about 30 minutes.
