Evidence is growing that the March 11 earthquake itself caused major damage to the Fukushima Daiichi reactors even before the accompanying tsunami knocked out offsite power and ensured the subsequent meltdowns.

According to Keiji Miyazaki, professor emeritus of nuclear reactor engineering at Osaka University, the earthquake likely damaged the high pressure coolant injection system, part of the emergency core cooling system at Unit 3 (as we reported below, it already has been believed that Unit 1 suffered severe damage from the earthquake). This system is supposed to work to cool the reactor even if power is lost, but at Unit 3, it didn't. A review of pressure readings at Unit 3 indicate that there likely was a major steam leak that ultimately led to the speedy meltdown there. Article from Asahi.com here.

US: Three Dead in Atlanta After Latest Storms


Three people died in the Atlanta area after straight-line winds gusted to 80 miles per hour on Thursday, ripping across parts of the South in the latest round of violent weather to tear through the U.S.

Nineteen-year-old Alonzo Daniel of Mableton was cleaning debris in his driveway on Stroud Drive when a tree fell on top of him, according to his family.

"As he was running, the tree caught him," Daniel's grandfather Robert Johnson told ABC News affiliate WSBTV in Atlanta.

Additionally, two women were crushed by a falling tree in the Buckhead section of Atlanta. The women were in a Mazda Miata convertible in the early evening when they driver lost control and crashed into a mailbox, firefighters told WSBTV.

Thursday saw more than 600 reports of severe weather across the country, including five tornadoes that stretched from the Gulf to Canada and as far east as Vermont. In New Orleans, four people were injured by the high winds.

Golf ball to baseball-size hail was reported in West Virginia, Maryland, Tennessee, Vermont and in western New York State, but resulted in only minor damage.

US: Oklahoma Tornadoes: Death Toll from Tornadoes Rises to 10

Oklahoma tornadoes: A teenage girl and her boyfriend were among the deceased, along with a 3-year-old Piedmont boy whose body was found Thursday morning.


A teenager who loved the rodeo, two children ripped from their mother's arms and a woman intent on saving her dogs were among those killed in the deadliest Oklahoma tornado outbreak in more than a decade.

Two days after the tornadoes left a path of destruction from Chickasha to Stillwater, authorities on Thursday recovered the body of a 3-year-old boy lost in a twister and finished identifying all 10 known victims.

The tornadoes left at least 238 people injured. Typical sheltering places, bathrooms and closets, could not withstand some of these killing winds. Initial reports indicate more than 600 homes and businesses were damaged, according to the Oklahoma Department of Emergency Management. The National Weather Service said that in terms of loss of life in Oklahoma, this was the worst tornado outbreak since May 3-4, 1999, when 44 people died in the state.

Rare Triple Sky Treat: Lunar, Solar Eclipses in June and July

Eclipse
© Starry Night SoftwareShortly before midnight on June 1 in Tromsø, Norway, the partially eclipsed sun will hang just above the northern horizon.
Over the next month, the world will experience three eclipses: two partial solar eclipses a month apart and one total lunar eclipse exactly in between, and it all starts with a so-called "midnight" eclipse of the sun.

A solar eclipse at midnight? How is such a thing possible?

It can happen near midsummer in the high Arctic, the land of the midnight sun. And it will happen next week on June 1 and 2, visible in the northernmost reaches of North America, Europe, and Asia.

These two solar eclipse sky maps available here detail what observers could see during some of the upcoming eclipses of the sun and moon in June.

US: The Weather Phenomena Causing 2011's Tornado Explosion

Meteorologist Jeff Masters says that while it might not be climate change, the tornadoes are just one of many weird weather phenomena this year that may be signaling major shifts in the climate.

From April 25 to 28, 2011, a fierce and deadly storm system produced a total of 327 confirmed tornadoes in 21 states from Texas to New York, and even isolated tornadoes in Canada. Alabama was struck particularly hard. These April 2011 tornadoes killed at least 344 people people in the Southeast, Midwest, and Northeast. Then--on May 22, 2011--the deadliest single tornado since 1953 struck Joplin, Missouri, with at least 124 people now confirmed dead and more than 1,000 people reportedly injured. Shortly before the tornado struck Joplin, EarthSky spoke to meteorologist Jeff Masters of Weather Underground. He explained some of the science that has caused these fierce 2011 tornadoes in the U.S.

In particular, he said, the location and strength of the jet stream played a role.

"The jet stream, which is that powerful river of air aloft over the country, turned out to be very strong this year. It had very high wind speeds in it. And it was moving over tornado alley, where we tend to get cold, dry air from Canada colliding with warm, moist air from the Gulf of Mexico. The combination of those contrasting air masses, and then the very powerful jet stream, was just the perfect storm of conditions to make a lot of tornadoes."

China drought ignites global grain supply concerns

A prolonged drought in China could hit grains output in key growing regions, further squeezing global supplies and putting upward pressure on prices, but plentiful domestic wheat stocks will act as a cushion and keep import volumes low.

Analysts are closely watching the weather in China, warning any further supply shocks in the grain markets would fuel a further rally in U.S. corn and wheat futures, already stoked by harsh crop weather in the United States and Europe.

"Parts of China have been too dry and if we did see crop failures in that part of the world they are going to look to the global market for supplies," said Luke Mathews, a commodity strategist with Commonwealth Bank of Australia in Sydney.

"They are going to be looking to North America and Europe and there is significant amount of concern whether those particular countries will be able to satisfy those needs."

NASA sees a 14-mile-wide eye and powerful Super Typhoon Songda

Typhoon Songda became a Super Typhoon in the evening on May 26, 2011 (Eastern Daylight Time) was it reached a Category 5 status on the Saffir-Simpson Scale. NASA satellite data shows that the monster storm with a 14 mile-wide eye has weakened due to adverse wind conditions today and is still a powerful Category 4 typhoon.

At this time, Songda was a Category 4 storm. The purple areas indicate very strong thunderstorms with heavy rainfall and there is a large area of them that surround the visible eye. Taiwan is northwest of the storm.
The Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of Super Typhoon Songda on May 27, 2011 at 5:05 UTC (1:05 a.m. EDT). At that time Songda was a Category 4 storm. The infrared image showed a large area of very strong thunderstorms with heavy rainfall surrounding the eye of the storm. The eye is almost 14 miles (12 nm/22 km) in diameter and those thunderstorms were dropping rainfall as much as 2 inches (50 mm) per hour.

On May 27 at 1500 UTC (11 a.m. EDT), Typhoon Songda's maximum sustained winds were near 125 knots (143 mph/231 kmh) down from its peak of 140 knots (161 mph/260 kmh) which it reached late on May 26. Sondga has tracked north-northwest but is expected to turn to the north-northeast.

Five Years On, Indonesia's Mud Volcano Still Erupting

Porong - "Lusi" the mud volcano is slowing down five years after it engulfed fields, homes and factories in a heavily populated part of Indonesia, but experts say the danger may last for decades.

Almost every minute another jet of thick, boiling, foul liquid shoots into the sky followed by a white cloud of vapour, adding to the vast lake of mud which now covers more than 700 hectares (1,730 acres) of Java island's Sidoarjo district.

"My whole life is buried here. I've lost everything: my house and the warung (streetside food stall) I opened just before the disaster," said Harwati, a 35-year-old widow and mother-of-two who now guides tourists around the disaster zone.

"Since then, life has been really hard. It's difficult to find a job."

She is one of some 40,000 people who have been forced out of their homes by the inexorable ooze, which appeared without warning on May 29, 2006 in the middle of a rice field.

Gradually, the mud has swallowed 12 villages, 30 factories, dozens of shops and a busy highway near the country's second largest city of Surabaya. Twelve people have been killed, but many more lives have been wrecked.

As the mud continues to flow, a row over its cause also festers with some experts and victims accusing a local gas drilling company of sparking the torrent - an allegation it denies.

Canada: Sinkholes Have Residents Fleeing Quebec City Neighborhood

Sinkhole
© CBC/Radio-CanadaQuebec City officials said experts will be on this Charlesbourg district site Friday to find out what's causing sinkholes.
Officials in Quebec City are trying to figure out what's caused dozens of sinkholes to appear in a north-end neighbourhood.

They served evacuation papers on Wednesday to about 15 homes and one business in the city's Charlesbourg district.

Almost 40 holes between five and eight metres wide appeared in the last week. The holes were mostly found in a field, but another was in a resident's driveway. One is big enough to fit a car.

"The field is is like, there is nothing, no trees or anything and you see everywhere some holes, some deeper than others, like 30 or 40 holes everywhere on the field. You can see this is not normal. You can see this is a problem on this land," said city spokesperson François Moisan.
