Bubble of methane triggered rig blast in Gulf of Mexico


The deadly blowout of an oil rig in the Gulf of Mexico was triggered by a bubble of methane gas that escaped from the well and shot up the drill column, expanding quickly as it burst through several seals and barriers before exploding, according to interviews with rig workers conducted during BP's internal investigation.

While the cause of the explosion is still under investigation, the sequence of events described in the interviews provides the most detailed account of the April 20 blast that killed 11 workers and touched off the underwater gusher that has poured more than 3 million gallons of crude into the Gulf.

Portions of the interviews, two written and one taped, were described in detail to an Associated Press reporter by Robert Bea, a University of California Berkeley engineering professor who serves on a National Academy of Engineering panel on oil pipeline safety and worked for BP PLC as a risk assessment consultant during the 1990s. He received them from industry friends seeking his expert opinion.

A group of BP executives were on board the Deepwater Horizon rig celebrating the project's safety record, according to the transcripts. Meanwhile, far below, the rig was being converted from an exploration well to a production well.

South America Gets Rattled By Quake

South American countries Peru, Bolivia and Chile were all rattled by a 6.4 magnitude earthquake early Thursday, May 6.

Hundreds of Peruvians fled for safety in Tacna, Peru, around 26 km from the epicentre. The quake struck near the border of the three countries and was even felt in La Paz, Bolivia -- where the intensity was around 3 or 4.

Buildings shook and walls cracked but there have been no reports of heavy damage or deaths,

The movement in Chile was very strong --which didn't help ease people's earthquake fears. The country has been spooked since the February earthquake killed hundreds of people north of Santiago.

Flash Floods Kill At Least 66 People in Afghanistan

Flash floods have killed at least 66 people and destroyed hundreds of houses in Afghanistan, the Government said.

Hundreds of livestock have also been destroyed by the flooding, caused by torrential rain in northern and western Afghanistan, said the head of the National Disaster Management Authority for the region.

"Twenty-three people have died in Badghis, 21 in Ghor and another 22 in Herat province,'' said Abdul Hameed Mubariz Hameedi, referring to the three worst-hit provinces.

The Afghan government and the United Nations have sent relief teams to the affected areas, which are among the poorest in the country.

Natural disasters are common in mountainous Afghanistan, where more than 200 people lost their lives in heavy avalanches earlier this year.

Thunderstorms Kill 43 People in India

Fierce thunderstorms have uprooted trees and destroyed hundreds of homes, crushing dozens of people to death and injuring scores of others in northern India.

At least 43 people were killed and 70 hurt in the deluge and squalls.

The powerful storms slashed a wide swath across Uttar Pradesh and Bihar states, uprooting trees and power pylons and damaging homes and crops.

In eastern Uttar Pradesh, 21 people were killed and about 50 others injured when heavy rains lashed the region, police spokesman Surendra Srivastava said.

"A majority of the victims were crushed under uprooted trees or when houses collapsed due to the squall,'' he said.

An earthquake has shaken the west of Ireland for the first time since records began.

Locals felt their houses shaking and heard loud bangs as the mini-quake, measuring 2.6 on the Richter scale, hit north Clare on Thursday night.

Liscannor resident Martin Doyle said: "I felt the whole roof shake. I thought the wall was collapsing. My neighbour called and he thought that the sound he heard was me falling down the stairs."

Rosemarie Buckley, who lives nearby, also said: "The house shook and we heard a loud bang."

Her husband Tom added: "We didn't know what it was. We thought it might have been a meteorite or something."

Best of the Web: North Pole rainfall 'bizarre': climatologist

north pole
Spring showers are next to non-existent in the High Arctic, so Environment Canada's senior climatologist says he's baffled to hear that it rained near the North Pole this week.

A group of British scientists working off Ellef Ringnes Island, near the North Pole, reported being hit with a three-minute rain shower over the weekend. The group reported the rain on Tuesday.

Rain in the High Arctic in April is nothing short of bizarre, said David Phillips, senior climatologist with Environment Canada.

"My business is weird, wild and wacky weather, and this is up there among fish falling from the sky or Niagara Falls running dry," Phillips told CBC News in an interview that aired Thursday.

"I mean, it really is strange. You just don't expect it to rain in the High Arctic in April; maybe in July and August. And certainly for these scientists from Europe coming over, they must have been also mystified."

Phillips said 50 to 60 years of historical weather data show no signs of rainfall ever occurring in April in the High Arctic.

The earliest account of measurable rainfall at Canadian Forces Station Alert took place on May 21, 1988, he said.

Comment: There was another related report about freak snowing in Antarctica nearly two years ago:

Something Strange is Happening at the Coldest, Driest Place on Earth
"Everyone talks about the melting of the glaciers but having day after day of rain in Antarctica is a totally new phenomenon. As a result, penguins are literally freezing to death."
...

With all that ice, it might seem kind of backwards to call snow at the South Pole "freaky," but it is. The Antarctic is literally a desert of ice with an average of 1-inch of precipitation each year.
...

Within hours the crystals thickened and turned heavy - and soon visibility would be completely chocked off. By midnight a rare easterly rose, climaxing at to 40 knots. What began as a crystal dance now turned to a full-blown blizzard - the equivalent of torrential rain in the middle of the Sahara. What I was seeing was real, the world had indeed turned upside-down, and it would be more than a week before it could right itself.

Chongqing - Storms killed at least 39 people in the southwestern and central parts of the country from Wednesday night to Thursday, local government authorities said.

As of 4 pm on Thursday, 29 people had died in the Dianjiang and Liangping counties as well as Fuling district of Chongqing municipality, with one other person missing, local government sources said.

Similarly, torrential rain that started at 2 am on Thursday in Xinhua county of Hunan province also killed four people and left one other person missing, authorities said.

The rains also triggered massive landslides and mudslides.

The extreme weather that started on Wednesday night in Chongqing had left 190 people injured as of 3:45 pm on Thursday.

The storms hit seven counties in Chongqing, with Hanjia and Pengshui reporting rainfall of up to 157 mm in the 24 hours to noon on Thursday, while wind speeds of up to 112 km per hour lashed worst-hit Dianjiang and Liangping.

"The trees in front of my house were uprooted or broke into half. My house roof, which was made of steel boards, was also ripped apart," said Liangping resident Huang Hongzhi.

"I have never seen it this bad before," he told China Daily.

Beijing - The death toll from fierce storms and torrential rains that ravaged southern China this week has risen to 65 with tens of thousands left homeless, authorities said Friday.

As of Friday, the storms had affected up to 2.55 million people and 100,000 hectares of arable land, leaving 65 people dead, 14 missing, 9,900 buildings damaged, said the Office of State Flood Control and Drought Relief Headquarters in a statement on its website.

Heavy rain has poured down in south China since Wednesday, including provinces of Guangdong, Sichuan and Guizhou, causing floods, mountain torrents and mud flows.

The office initiated a level-four emergency response on Friday to cope with the chaos caused by storms sweeping its southern provinces.

The office has ordered local authorities to closely monitor the development of the rainstorms, prevent weather-triggered disasters like floods and landslides and provide early warnings.

The office has also dispatched working teams to storm-hit regions to enhance storm-relief work, it said.
