It’s almost 5 years since the Great East Japan earthquake – Fukushima still has a long way to go

From the article:

About 1,000 tanks storing more than 700,000 tons of contaminated water could be seen in the wide spaces in front of buildings accommodating reactors Nos. 1 to 4, where the decontamination and decommissioning work is being conducted.

Within the site, work to remove contaminated surface soil and pave over the scoured ground has been continuing. Thus levels of radiation are generally becoming lower.

In contrast, there are facilities for which decontamination work has not been carried out at all, and vestiges of the accident remained visible in some places.

From an area 35 meters above sea level, where a group of tanks and other facilities are located, I went down a slope by car and approached a building accommodating the No. 4 reactor, which is located at a spot 10 meters above sea level. I saw that the walls still bore black traces of the tsunami that hit the nuclear power plant following the earthquake.

When the car I was in passed by the No. 3 reactor building, where a hydrogen explosion had occurred, a dosimeter indicated 230 microsieverts per hour.

A tolerable annual limit of exposure to radiation for ordinary people in usual times is said to be 1 millisievert (1,000 microsieverts). The figure on the dosimeter means that a person’s exposure level would exceed the limit if they stayed there for about four hours.

The highest radiation dose of any place in the plant is near an air stack, which is about 120 meters tall, near reactors Nos. 1 and 2.

A TEPCO official explained, “In 2013, the radiation dose was estimated to be about 25 sieverts (25 million microsieverts) per hour. Though about five years have passed, no measures have been taken.”

It’s quieted down now but was magnitude 8.5!

The earthquake went on for minutes. First it was slow and rolling, then suddenly strong. My house is still moving slightly.

The epicenter was Tokyo prefecture, technically, but near Ogasawara, which are islands pretty far off the coast.

On the Japanese Shindo scale of 1-7 it was a 5+ at the epicenter. Shindo 4 where I live.

The magnitude was 8.5, but very deep – 590 km.

No damage in my house. Just a lot of shaking. No tsunami warning.

A separate earthquake woke me up at 1:06 am.

 

 

Earthquake over. Everything ok.

It was a Shindo 4 by me (on the Japanese 1-7 earthquake scale). Shindo 5 at the epicenter in northern Saitama. Magnitude 5.6.

The iPhone helpfully said “Earthquake. Earthquake. Earthquake” in Japanese. Like, “duh.”

Some things fell over, but it passed quickly. I thought my monitors might fall over but they didn’t.

All over for now.
