It was two earthquakes -- one "small" one and another "big" one that followed about a minute later. On TV, they were announcing the quake intensity of the first one and and there was a video feed of the Fukushima nuclear plant, as they usually do when there's a strong quake in that area. A moment later, the feed was shaking violently -- I thought it was a replay of what was taken earlier, but it must have been the "big" one. In Tokyo, we felt the secondary wave of the first overlapping with the primary of the second, so it was disorienting and scary. Although the quake intensity itself wasn't serious in Tokyo.

Well, seems like a Shinkansen derailed. It doesn't seem very serious as there's someone tweeting about it from inside that train...[1] There's also a tweet that the part of the overhead power line broke off and fell[2], so it may take a while to get back in service...

  I would be interested to know more about the derailing. The shinkansen network has automated quake protections that stop the trains when a quake is detected, while that's not a foolproof system, I am sure a derailment at full speed would be very different to this picture. Either it worked or the train was at a slower part of it's journey, perhaps even stopped.

    Shinkansen moves fast enough it's difficult to fully stop in time unless it gets a decent amount more warning. Probably slowed down enough it was pretty minor though.

    It probably slowed down/stopped for the first quake before the 7.3 hit and derailed it?

The big wasn't still very big here in Tokyo, but it felt weird. The shake was in different direction than usually, it's hard to describe. It also lasted quite long in detectable intensities, although the peak shake was over pretty quickly.

  That’s the transverse Secondary wave from a distant origin. It feels like you’re suddenly put on a ship rather than like the ground exploded. I learned that anecdotally…
