Japan Issues Highest Alert Over Typhoon Neoguri

Japan was bracing Tuesday for one of its worst storms in over a decade as typhoon Neoguri barreled towards the southern Okinawa island chain, with 55,000 people urged to evacuate as the weather agency issued its highest alert.

The top-level warning means a threat to life, as well as the risk of massive damage from torrential rains and gusts of up to 250 kilometres (155 miles) per hour. . .

. . . Waves could reach as high as 14 metres (45 feet), a weather agency official said in a warning that was likely to revive memories of Japan's quake-tsunami disaster in 2011.

Big Typhoons May Collide Off Honshu


Double whammy feared; Izu braces for the worst - by Tomohiro Osaki - October 23, 2013

Less than a week after being hit by the largest typhoon in a decade, Tokyo is bracing for another strong storm that will likely reach the area Saturday, and it may get merged with an even stronger approaching tempest.

Though less powerful than Typhoon Wipha, incoming tropical cyclone Francisco is rated as “strong,” the Meteorological Agency said. But on a possible collision course is Typhoon Lekima, considered “more fierce.”

Typhoon Francisco on Course for Japan — May Follow Typhoon Wipha’s Path … Developed in a Similar Area (VIDEO)

      (CLICK ON IMAGE BELOW - NOAA - Francisco Long Floater - Infrared Channel 4 Imagery Loop) - Energy News - October 19, 2013

Weather Channel, Oct. 18, 2013 at 9:45p ET: Super Typhoon Francisco Brushes Guam, Could Threaten Japan Next Week [...] A tropical cyclone is dubbed a “super typhoon” when maximum sustained winds reach at least 150 mph – the equivalent of a Category 4 hurricane on the Saffir-Simpson scale. [...] Conditions appear favorable for development [... allowing] the typhoon to strengthen in intensity, possibly to 160 mph (Category 5 status) over the next few hours. After that, Francisco will move into a region of cooler ocean temperatures, which cause the typhoon to weaken. Francisco may threaten southern Japan early next week, however the current forecast from the Joint Typhoon Warning Center indicates that the typhoon will be much weaker by that point. That said, intensity forecasts at five days out in time can be highly uncertain [...]

IAEA Expert Remediation Mission to Japan Issues Preliminary Report


21 October 2013 | Tokyo -- The International Atomic Energy Agency (IAEA)'s international expert mission to review remediation efforts in areas affected by the Fukushima Daiichi accident concluded today with the presentation of a Preliminary Summary Report to Japan's Senior Vice-Minister of the Environment, Shinji Inoue.

The Follow-up IAEA International Mission on Remediation of Large Contaminated Areas Off-site the Fukushima Daiichi NPS recognised the huge effort and enormous resources that Japan is devoting to its remediation strategies and activities, with the aim of improving living conditions for people affected by the nuclear accident and enabling evacuees to return home.

The Mission Team highlighted important progress since the first IAEA remediation mission in October 2011, noted that Japan had made good use of advice from that earlier Mission, and offered fresh advice in a number of areas where it is still possible to further improve current practices, taking into account both international standards and the experience of remediation programmes in other countries.

OCHA - Japan: An Earthquake, a Tsunami – and a Handwritten Newspaper

When one of the most technologically sophisticated countries in the world is hit by a triple emergency, should we count on web platforms and social media to deliver lifesaving information? Not necessarily, according to a new report by Internews into the communications aspects of the 2011 earthquake, tsunami and nuclear disaster in Japan.

. . . instead of their usual high-tech operation, local newspaper reporters went back a few decades in time and produced a handwritten newspaper.

Fukushima Disaster “a Profoundly Man-Made Disaster”: Investigative Commission

Executive Summary - (88 page .PDF file)

NAIIC Report

The commission investigating the Fukushima disaster of March 2011 concluded that although the combination of the tsunami and earthquake was unprecedented in its ferocity, the disaster was largely man-made because it was amplified by what came before it and what followed it. The disaster itself, the Fukushima Nuclear Accident Independent Investigation Commission, said was sandwiched by practices and conduct which were the result of government-industry collusion and the worst conformist conventions of Japanese culture.

Fukushima Lesson: Be Ready for Unanticipated Nuclear Accidents

Homeland Security News Wire - March 12, 2012

A year after the Fukushima disaster all but two of Japan’s fifty-four nuclear reactors remain shut down, in a country where nuclear power once supplied nearly 30 percent of the electricity; the Japanese government is awarding an initial $13 billion in contracts to begin decontamination and rehabilitation of the more than 8,000-square-mile region most exposed to radioactive fallout

A year after the crisis at Japan’s Fukushima Daiichi nuclear power plant, scientists and engineers remain largely in the dark when it comes to fundamental knowledge about how nuclear fuels behave under extreme conditions, according to a University of Michigan nuclear waste expert and his colleagues.

In a review article in this week’s edition of the journal Science, U-M’s Rodney Ewing and two colleagues call for an ambitious, long-term national research program to study how nuclear fuels behave under the extreme conditions present during core-melt events like those that occurred at Fukushima following the 11 March, 2011, magnitude 9.0 earthquake and tsunami.

Japan Questions Earthquake Forecasts

submitted by Samuel Bendett

Homeland Security News Wire - March 2, 2012

Following the massive 11 March earthquake and tsunami that rocked Japan, residents and experts there have grown increasingly skeptical of quake forecasts.

Last month two University of Tokyo seismologists released a study that predicted a major earthquake would hit Japan’s capital city within the next four years. Their study was sharply criticized by those who said their claims were likely incorrect.

Bowing to pressure, the university’s Earthquake Research Institute posted a notice on its site that stated the latest earthquake forecast was the opinion of two researchers and noted the study’s “large margin of error.”

“Many seismologists think this kind of study is too simple,” said Naoyuki Kato, a seismologist at the institute, in an interview with the Washington Post.

Japan, which has been frequently rocked by powerful earthquakes in the past, invests more money than any other nation in the world on earthquake prediction, yet despite spending more than $100 million annually, the art of predicting earthquakes remains elusive.
