      Well, they were talking about the chance of an “aftershock” occurring in the wake of last month’s 7.3 earthquake. This time it is tentatively being called a 7.2 and it occurred a few minutes ago off the coast of Miyagi Prefecture in northeastern Honshu, in roughly the same place as the megaquake of 10 years ago. Fortunately, the chances of a major tsunami are small, and it didn’t quite make it to Level 6 (“disastrous”) on the Japanese 7-level intensity scale. But it certainly must have shaken up a lot of people along the eastern Pacific coast.

      including 2 in Japan near the 2011 megaquake epicenter.

      Today’s quake lasted about 1 minute, according to NHK Radio. That’s a long time for a typical Japanese earthquake. However, the 2011 M9.0 quake lasted more than 4 minutes.

      the “Ring of Fire” in the Pacific, but is there a connection between the quake in New Zealand and the one now in Japan? Or are you talking about another one which happened “last month” in Japan?

      broadcast in South Korea. The public interest group there is focused primarily on Wolseong, in Gyeongju, North Gyeongsang province, South Korea. (Southeast coast, on East Sea/Sea of Japan.) The reason, the nuclear power facility at Wolseong has aging reactors. Reactor one was leaking, supposedly it was fixed some time ago, its service life was extended ten years from its anticipated 30 year useful life. More leaks were discovered and the Moon administration shut it down ahead of schedule which caused an uproar among conservatives. Now Wolseong 3 reactor has a lot of highly radioactive water in the sump. I know from a previous broadcast some contamination has been detected in ground water samples inside the nuclear sites boundaries.

      It looks like the nuclear plants at Wolseong were built not too far from a series of fault lines in South Korea. So the public interest groups from the community there compare the potential problem to that in Fukushima from the 2011 disaster.

      Unfortunately, I don’t have the expertise nor the necessary vocabulary to fully comprehend the program. They read the contamination in beq/kg which i don’t understand. This particular broadcast talked about the South Korean government’s inspection of foods coming from the region of Japan more or less proximate to Fukushima, the region shown in the graphic above in the OP. What I gathered was that up to about 17 percent of certain foods from this region have detectable levels of radioactive contamination. Importation of seafoods from these regions (where the dots are on the OP graphic) into South Korea is prohibited.

      Notably, certain foods were much more likely to carry unsafe levels of contamination. Wild meat, specifically wild boar, were highest. (these areas have had no remediation efforts) For some reason, in cultivated areas, dried persimmons had relatively high levels of radioactive contamination and detection at 80bq/kg. (because they hang in open air outside to dry?) So did ferns. Fortunately domesticated meats and livestock had low levels of radiation and rates of positive detection. The detection rates and level of radiation detected in fish and seafood products was apparently significant. Their importation from the affected prefectures is prohibited. Radiation in honey was detected at 15bq/kg. Tofu, among processed agricultural products from this region of Japan, had contamination detected at 30bq/kg. Dried persimmons were highest at 80bq/kg among those products where contamination was detected below 100bq/kg.

      Tofu, persimmon production, and sea foods, are major endeavors in South Korea. I got the impression that the point of the broadcast was that Wolseong has the potential to become another Fukushima like occurrence with a potential adverse impact on important sectors of South Korea’s agricultural and seafood economy. They were studying Fukishima for indicators of what could happen in South Korea as well. If there are any physicists out there I can post the video link, where the numbers are posted on some graphics; unfortunately the program is entirely in Korean. I had asked a person I knew who has a physics degree to do the conversion of similar measurements from a previous report and give their opinion on the risks at Wolseong once before but they declined.

      The English language media avoid this Wolseong nuclear problem. This is my interpretation of another investigative report from South Korea’s MBC News in January:

      but global warming has theoretecally expanded the atmosphere and therefore slowed the Earth’s rotation ( proven, by a handful of microseconds) this has changed the stress factors in the crust, leading to more and worse tectonic shifts.
