Japan 7.3 Quake. Videos of Fukushima, ground shaking the next hours. Aftershocks or Pre-shocks?

A large quake hit Japan today (12/7/12) close to where last year's quake hit that began the Fukushima nuclear nightmare, besides the horrible lost of life and tsunami that wiped away whole areas of Japan. 

Below are videos of Fukushima, when the EQ hit today.  You can see the violent shaking of the camera.  It is towards the end of the first video, but watch how quakes continue to affect the camera and shake the earth over and over again in the 2nd video which is the next hour after the initial 7.3.
The videos are 20X speed of the hour.  

What I find very interesting is I can not find more videos since then from JNN/TBS, besides that it seems the videos I have below are now off the list of JNN videos available.  I have copied the videos below to my computer, in case they are not available later. 

I have news articles after the videos with the latest about Fukushima in the Japanese media.  One article was just released today about the amount of radiation the workers (20,103) of Fukushima have received, but that data and amount of workers, only goes to January 2012 ( a year ago now).  Why don't they have it up until now, why the last information from January 2012?

Here is the map of the quakes so far with it showing the location of the 9.0 on March 11, 2011:

Here are the quakes so far in the Japan area where the large quake hit last year.  These could be considered after shocks of last years quake, as per the media.

I have put in the above information, due to the fact the quake of today is on the fault itself, compared to last year's quakes.

So the question then is... are these after shocks or pre shocks considering the ones happening now are in a different place, yet near by?



Article of radiation per age group at Fukushima I mentioned at the beginning of the post:

Tokyo Electric Power Company says a teenage worker at the Fukushima Daiichi nuclear plant was exposed to radiation levels at least 50 times higher than Japan's maximum permissible dose for the general public.

The annual maximum radiation exposure limit for the public is set at one millisievert.

The utility company disclosed data on Thursday that it submitted to the World Health Organization in March. The data includes details of the radiation doses that workers were exposed to at the plant.

A total of 20,103 workers took part in post-disaster operations between March 2011 and the end of January this year.

The youngest was aged 18 while the oldest was 84. Those in their teens numbered 64. One of them was exposed to a cumulative radiation dose of 56.89 millisieverts, the highest for his age group.

A TEPCO employee in his 30s received 678.8 millisieverts, the highest dose among all the workers.

Those in their 20s were exposed to an average dose of 15.86 millisieverts, the highest among all the age groups.

Workers in their 40s were the largest group at 5,893. They had an average exposure of 11.64 millisieverts.

The annual maximum permitted level for plant workers is set at 50 millisieverts. This makes it difficult to retain experienced workers for long periods. The ongoing decommission work is expected to take several decades.
