Update On Us and Our Area Part 2

I am terribly sorry for being lazy and not updating for a while and not visiting your blogs lately...

As I already said a couple of times in my last two posts, our family members are all fine in the northern part of Kanto area- Utsunomiya city, Tochigi Prefecture. When compared to what people in the coastal region in Tohoku area have been suffering, our damage is extremely subtle. As you can see in the photo above, occasionally old buildings are shown to be half collapsed. These buildings are in the process of demolition, because otherwise a total collapse caused by aftershocks is very likely.

Fig. 1 The frequency of quakes. Gray bars (left) indicate quakes that happened before the major disaster (red). The Y axis denotes the numbers of aftershocks per hour and the X axis indicates time.

Numbers of aftershocks are getting fewer and fewer, although it still shakes significantly more than before the major quake (red bar on March 11th, 14:46 Japan Time).

Fig 2. Average magnitude of aftershocks. The red bar reached at magnitude 9 which is the biggest number ever recorded in Japan. Y axis indicates average magnitude of aftershocks per hour. Gray bars denote quakes that happened before the major disaster.

The magnitude of aftershocks remains unchanged...


The only concern we are facing in the Kanto area is a lack of gasoline, which is mostly attributed to the psychological (= hysterical) reaction of the customers, combined with the temporary decreased supply from the vendors... Hope that the situation will be improved next week.

Our government is doing their best to prevent from the worst case scenario at Fukushima Daiichi nuclear power plant. Lots of rumors are spreading in all sorts of media you can think of as to what is likely to happen in the northern part of Japan but I have been visiting one site from time to time for updates on the power plant in a critical situation. It is also useful for future prospects.

I strongly recommend everybody to take a look at this article posted on March 16 there. Dr Don Higson actually has said everything that's been on my mind and there's absolutely nothing else to say. Dr Don Higson is a retired nuclear safety specialist and Fellow of the Institution of Engineers Australia, Fellow of the Australasian Radiation Protection Society.
Sure, this is an article posted three days ago and what was written is not what is happening now but I agree with his interpretations of the events that occured at Fukushima Daiichi nuclear power plant.

Dr. Higson's personal views started as follow:

I believe it will eventually be understood that events over the past few days at Fukushima Daiichi nuclear power station in north-eastern Japan have demonstrated the safety of nuclear power. In what may have been the worst earthquake and tsunami ever to have occurred, the approximately 40-year old nuclear plants have been severely damaged. Three of them are likely to be written off - like many other industrial installations in that part of Japan. However, the reactor containments have remained intact, releases of radioactivity outside the site boundary have not reached dangerous levels and there is no risk to the general public.

For over a decade I have been using radioactivity at the university and I am not so concerned about low levels of radioactivity in our region...

Have a wonderful weekend.
