I did not know because the scene was a bit confusing on the day, but it looks like I was shutting the shutter.
The situation just before the accident is from the following. It is somewhat different from the state that it has been reported so far.
First of all, this is the movie immediately after 10 am on August 3. You can see that the escalator moves slowly upwards. As you can see, no one is running or moving on the escalator. It is just a ride.
The shooting time of this photo is 10: 1: 6. The collapse has not yet begun, it is moving. The one on the left side goes down and the one on the right side goes up (one who caused the accident).
It is just before collapse at 10: 1: 10. In some press reports "It suddenly stopped when the head reached the third floor partAlthough there is, in fact the first security guard has arrived on the fourth floor. And, if you see it, people are riding from the top to the bottom without gaps.
And this is the very moment when the collapse began, at 10:01 and 13:00. People on the descending side have big noises and swayed, so you can see that they are watching the upstream side all at once.
It is this that cut the photo of the previous size. People who are the leader of the Wonder Festival wearing an orange shirt on the descending side and all the people behind it are watching at once. Because there was a big noise and it stopped suddenly, you can see how all the people on the upstream are trying to cling to the railing and everyone is watching the feet. Also, the person in the lower right of the photo sees the "upper person" on the upload side, you can tell that the sound that you looked back unexpectedly from around it.
The image immediately after this is published on the TBS site.
