First it glows small once

One more time

The third light emission is behind the building

It glows big enough so that the outline of the building can be clearly seen

Then start to shine strongly and strongly at the center of the screen ...

The light grows steadily and steadily

The light becomes stronger ...

The color also changes

It glows small again at the right next to it

Once it gets weakened, the light becomes even stronger

Becomes smaller ...

It glows next to me ......

Light will shrink and shrink as it shrinks

I can not see it anymore.

And Sendai suffered a power outage shortly after the light went out

Short at short substation or NHK news when earthquake occurs

In this direction there is the Sendai substation of Tohoku Electric Power Co., and when a helicopter of NHK shot from the sky on the morning of the morning 8, it seemed that the substation equipment was scorching. According to Tohoku Electric Power, this Sendai substation is that the substation called "Disconnector" which switched the route to send electricity failed due to an earthquake on the 7th night, and the substation function temporarily stopped. In the restoration work thereafter, it means that it recovered to the state where electric substation and power transmission are possible before 6 am in the morning. Regarding the relationship with the sparks reflected on the camera, Tohoku Electric Power is talking about "Breakdown of the disconnector, it seems that some sort of electric shortage occurred at the Sendai substation", and I am investigating the detailed circumstances.
