News in Japan - November

Japan:
Study says Tokyo, Osaka, other mega-cities will be swamped by surging sea levels, even at 2 degrees Celsius rise A spike in Earth’s temperature of 2 degrees Celsius (3.6 degrees Fahrenheit) would submerge land currently occupied by 280 million people, while an increase of 4 degrees Celsius - humanity’s current trajectory - would cover areas populated by more than 600 million people, the study said.
In the capital, 7.5 million people - 30 percent of Tokyo’s population - would be affected by the sea level rise under the 4 C scenario. A rise by 2 C would leave 4.2 million people’s homes underwater.
In Osaka, 6.2 million people - a staggering 38 percent of its population - would be affected under the 4 C rise. Under the 2 C scenario, the city would still see 4.2 million affected.
Sea level rises corresponding to these 2 C or 4 C scenarios could unfold in two hundred years, but would more likely happen over many centuries, perhaps as long as 2,000 years, according to the research, published by Climate Central.

Abstract
Despite sincere efforts by concerned agencies and recent improvements in hazard warnings, thousands of at-risk people did not evacuate during Aila, a category-I tropical cyclone that struck southwestern coastal Bangladesh in 2009. This study investigated the responses of the people affected by Aila to cyclone warnings and associated evacuation orders, and unveiled behavioural aspects that explain why they did or did not comply with the evacuation orders. Utilising the primary data collected from 420 households living in the severely affected coastal sub-district Koyra, located in Khulna District, this study found that although more than 97% of the households had received cyclone warnings and evacuation orders before Aila's landfall, only around 26% had evacuated. We also examined this study's empirical findings for factors that had dissuaded people from complying with the evacuation orders. Relevant test statistics along with results from principal component analysis suggested that the significant and systematic absenteeism of households from disaster preparedness training appears to be one of the key determinants that affected their evacuation decisions, along with factors related to warning messages, the attributes of cyclone shelters, risk perception, and socioeconomic aspects. A number of recommendations are also presented in this study for people at risk to improve their evacuation rates in future emergencies, not only to save their own lives but also to save their livestock.

Japanese flood and landslides:
Here are the latest statistics from the Japanese government's Fire and Disaster Management Agency and other national and local governments as of Friday, Sept. 18:
•        The death toll is eight: three in Tochigi Prefecture, three in Ibaraki Prefecture, and two in Miyagi Prefecture.
•        There are 46 confirmed injuries, with Ibaraki Prefecture accounting for 24 of them.
•        A total of 18,882 dwellings have been confirmed flooded. Ibaraki leads this list as well, with 12,088 flooded homes.
•        In addition to the flooded homes, 16 dwellings have been destroyed and another 102 have structural damage.
•        Damage also occurred to 61 non-residential structures.
•        Damage to the agricultural, forestry and fishing industries has reached 11.7 billion yen (about 98 million U.S. dollars).
•        At least 455 landslides were reported – 358 of them in Tochigi Prefecture alone, and 312 of those in the city of Nikkō, according to the prefectural government.
•        Up to 26 inches of rain fell in eastern Japan Sunday through Friday due to Tropical Storm Etau and its remnant low.
•        Local officials in Ibaraki Prefecture said 1,344 people had been rescued via helicopter by the country's Self-Defence Force and rescuers from 10 of the country's 47 prefectures.
Key developments in the storm:
•        On Wednesday, Sept. 16, officials confimed the death of a 40-year-old man who had been out on his bicycle when the floods hit Ibaraki Prefecture on Sept. 10.
•        A 60-year-old man was found dead Saturday after the vehicle he was in was swept into a flooded river Friday morning in the city of Kurihara, Miyagi Prefecture. A 48-year-old woman also died in that incident.
•        Japanese media said a pair of eight-year-old boys were among those found alive and removed from the list of missing Saturday.
•        Two men, ages 71 and 51, were found dead in rice fields flooded by the levee breach in Joso, according to public broadcaster NHK. The men were not previously among the list of missing.
•        The Japanese government's Fire and Disaster Management Agency confirmed that a man found dead in a flooded vehicle in Tochigi Prefecture Sunday morning died of storm-related causes.
•        A 63-year-old woman was confirmed dead after a landslide struck Kanuma city, Tochigi Prefecture, early Thursday. The woman was missing for hours before being found dead Thursday evening.
•        A man in his 20s was confirmed dead Friday after falling into a flooded drainage pipe Thursday in Nikkō city, Tochigi Prefecture.
•        Rare emergency weather warnings were issued for Tochigi, Ibaraki and Miyagi prefectures on Thursday and Friday, but have all since been lowered.
•        A magnitude-5.2 earthquake struck Tokyo Bay at 5:49 a.m. local time Saturday, rattling the entire Tokyo region and prompting fears of quake-triggered landslides in rain-soaked hilly terrain.
•        The earthquake injured seven people in Tokyo and its suburbs, according to the FDMA.
•        Another earthquake, rated magnitude 4.6 and centered off the east coast of Ibaraki Prefecture, rattled the Joso flood zone nearly six hours later but with weaker ground shaking.
•        The Shibui River broke through a levee in Ōsaki city, Miyagi Prefecture, on Friday morning. At least 1,000 people were stranded in floodwaters, according to the newspaper Asahi Shimbun.
•        The Japan Meteorological Agency issued the maximum "Level 5" flood warning Friday for the Yoshida River in Miyagi Prefecture and for the Mogamiogumi River in Yamagata Prefecture.
•        More than 800 people in the mountainous town of Minamiaizu, Fukushima Prefecture, were cut off from the outside world due to flooding and landslides on the lone highway through town Friday.
The Japan Meteorological Agency issued a rare emergency heavy rainfall warning for Miyagi Prefecture and its 2.3 million residents early Friday as torrential rains continued to drench the prefecture, which includes the city of Sendai, raising concerns of landslides and river flooding. The JMA observation site near Sendai's central business district reported 269 millimeters (10.59 inches) of rain in the 24-hour period between 7:40 a.m. Thursday and 7:40 a.m. Friday local time. (Japan is 13 hours ahead of U.S. Eastern Daylight Time.) JMA lowered the warning for Miyagi Friday evening.
"We can say this is an abnormal situation and there is imminent serious danger," said Takuya Deshimaru, chief forecaster at the Japan Meteorological Agency, according to the BBC.
On Thursday, JMA issued similar emergency weather warnings for 5 million people in Tochigi Prefecture and Ibaraki Prefecture, north and northeast of Tokyo, on Thursday morning. The warnings were issued as a band of heavy rainfall associated with the post-tropical remnant of Tropical Storm Etau stalled over eastern Japan, dumping up to 21 inches of rain in 24 hours near the head of the Kunigawa River, which drains south through the northern suburbs of Tokyo.
The emergency warnings in Tochigi and Ibaraki prefectures were lowered Friday morning.

Our colleague Dr. Ohara has shared videos made after the Joso city flood disaster.

The first video is taken on September 12th, two days after the flood occurred. This was taken in the North area, at the levee over-topping area, where solar farms were damaged.
