Belching Hawaii Volcano Shuts Park, Forces Evacuations


Associated Press
Thu, 10 Apr 2008 16:49 UTC
Hawaii Volcanoes National Park was closed for a second day Wednesday as officials waited for a change in wind direction to blow away sulfur dioxide belching from Kīlauea volcano.

National Park Service officials said air conditions had worsened since Tuesday, when 2,000 people were evacuated from the Big Island park.

"This morning, with it being cool and some warmer air on top of it, it has kind of created a pancake effect, so we have some more of the vog lower down," said Michael Larson, the park's incident information officer.

Vog, or volcanic fog, forms when sulfur dioxide gas reacts with sunlight, oxygen, dust particles, and water in the air. Tiny droplets known as sulfate aerosols are created, along with sulfuric acid and other substances.

Sulfur dioxide spewing from the volcano, which has been active since 1983, has closed Hawaii Volcanoes National Park for its second day and forced an evacuation of 2,000 people.

Massive study of Madagascar wildlife released


Wildlife Conservation Society
Thu, 10 Apr 2008 16:21 UTC
Using data from thousands of species of lemurs, frogs, geckos, butterflies, ants, and plants, scientists from the Bronx Zoo-based Wildlife Conservation Society, University of California, Berkeley and other organizations have completed an analytical colossus for Madagascar that will guide plans to safeguard the island's unique natural heritage. The massive study is the cover story in the most recent edition of Science.

The study is unprecedented in terms of not only the number of species examined (some 2,315 species in six groups), but also because of the project's scale and resolution. The biodiversity, climate and habitat of the entire 226,657 square-mile island, which is nearly a third larger than the state of California, were examined. The maps generated from the data analyses have a resolution of less than a square kilometer.

"While some of the key areas of biodiversity are under protection, many are not. This study will help direct conservation plans to help protect the most species possible, with special consideration given to those animals and plants that are most endangered," said the study's lead co-author Dr. Claire Kremen, an associate conservationist with the Wildlife Conservation Society and UC Berkeley assistant professor.

Scientists in northern Sweden believe they have discovered the world's oldest living tree, dating back nearly 8,000 years, local media said on Thursday.

A Norway spruce, which was found growing at a height of 950 meters above sea level, is more than two meters (6.5 feet) tall and about 20 centimeters (8 inches) in width.

US: Apparent tornadoes hit Arkansas, Texas, Oklahoma

A band of hail, heavy rain and twisters pounded Arkansas, Texas and Oklahoma Thursday, damaging hundreds of homes, flooding roads and leaving thousands without power.

Arkansas already was contending with three weeks of flooding and the aftermath of 10 tornadoes that struck last week when the latest storm hit.

"It's just getting worse," sheriff's dispatcher Nola Massey said. "We're just trying to get everybody to stay home and not get out in it."

Jeremy Dickey of Breckenridge, Texas, tries to turn off the water to his house after it was struck by an apparent tornado Wednesday evening, April 9, 2008. Dickey wasn't home at the time, but his wife, Tina, and two children, ages 4 years and 8 months, hid in an interior closet he had reinforced as a shelter. They were not injured, but the house was moved 10 feet off of its foundation. Breckenridge police said they have reports of a few minor injuries, but didn't have a full count. Power lines were down and at least five homes were destroyed, police said.

Sydney Harbors Deadly Diet For Sea Creatures


Science Daily
Thu, 10 Apr 2008 12:41 UTC
Contaminated seaweeds in Sydney Harbour could be threatening the small animals that feed on them, according to a new study revealing that the harbour's seaweeds have the world's highest levels of copper and lead contamination.

Up to 75 percent of the offspring of small crustaceans that feed on a common brown seaweed, for example, are killed when they are exposed to copper at levels found in some parts of the harbour, UNSW laboratory and field experiments have shown.

US, Chicago: Flood Season Begins Unusually Early Across Heartland

The flood season in the nation's midsection started early this year, and there's no letup in sight, spurring federal, state and local officials to brace for what looks likely to be an unusually watery spring.

At least 16 deaths were linked to heavy flooding across Missouri, Arkansas, Tennessee, Oklahoma and other states in March; another was tied to flooding Friday in Kentucky. Last week, snow that could set off more flooding blanketed parts of the Midwest. And Kentucky and parts of Arkansas and Missouri that are struggling to recover from previous deluges remained vulnerable to the threat of weekend rain.

The Pacific islands of Vanuatu and New Caledonia were shaken by a magnitude-7.5 earthquake, less than two hours after a magnitude-6.4 temblor hit the area, the U.S. Geological Survey said.

The latest quake struck at 11:46 p.m. local time, about 89 kilometers (55 miles) south-southwest of Isangel in Vanuatu, and 174 kilometers northeast of Tadine in New Caledonia's Loyalty Islands, the USGS said today in a preliminary report on its Web site. The quake struck at a depth of 89 kilometers and there were no immediate warnings of a potential tsunami.

Scientists probe earthquake clouds


The Press Association
Wed, 09 Apr 2008 22:30 UTC
Curious gaps in clouds may provide early warning of an earthquake, scientists believe.

Researchers spotted unusual cloud formations above an active fault in Iran before two large earthquakes struck the region.

It appeared to be more than coincidence, and now scientists are investigating whether clouds can predict major quakes.

'Well Above-average' Hurricane Season Forecast For 2008


Science Daily

The Colorado State University forecast team upgraded its early season forecast today from the Bahamas Weather Conference, saying the U.S. Atlantic basin will likely experience a well above-average hurricane season.

"Current oceanic and atmospheric trends indicate that we will likely have an active Atlantic basin hurricane season," said William Gray, who is beginning his 25th year forecasting hurricanes at Colorado State University.
