US: 4.3 earthquake measured 84 miles southeast of El Paso

A 4.3 earthquake shook part of West Texas and Northern Chihuahua late Wednesday, according to the U.S. Geological Survey.

The temblor was centered in the state of Chihuahua about 40 miles south of Fort Hancock, Texas, said Aaron Velasco, a seismologist and chairman of the Geology Department at the University of Texas at El Paso.

UTEP has a seismograph that records seismic activity.

Velasco said the earthquake occurred in an area that includes a valley used for agriculture and some mountains.

The earthquake began just before 11 p.m. on Wednesday and emanated from about 6.2 miles deep in the earth. The region of the epicenter is about 84 miles southeast of El Paso.

Velasco said the shaking took place in a region that does not appear to have a history of significant earthquake activity.

"There was a whole sequence of events," he said. "There was a 4.3 and a 4.1 earthquake and six to seven smaller ones. We're going to study this further."

US: Historic Flooding Unfolding Along Mississippi, Ohio Rivers

As if tornadoes and damaging thunderstorms were not enough, historic flooding is also threatening the Mississippi River, below St. Louis, as well as the lower part of the Ohio River.

The rising waters are expected to top levels set during February 1937. This mark is the middle Mississippi Valley's equivalent to the 1993 event farther north along Old Man River.

Even if rain were to fall at a normal rate for the remainder of the spring, the consequences of what has already happened in the Midwest will affect way of live, property, agriculture and travel/shipping/navigation for weeks in the region.

While the amount of evacuees currently numbers in the hundreds, it could soon number in the tens of thousands as levees are topped or breached and rivers expand their girth into more farming communities, towns and cities.

US: Tornadoes take staggering toll in Alabama and Deep South

A massive thunderstorm front spawned 137 tornadoes, killed at least 180 people, and mangled sections of Tuscaloosa, Birmingham, and Huntsville, Ala., on Wednesday. April is now one of the most violent weather months in the region in decades.

A line of violent thunderstorms - the latest in a deadly series - rolled across the Deep South Wednesday, spawning dozens of tornadoes, razing churches and fire stations, trapping people amid debris, and finally leaving at least 180 people dead, mostly from heavily populated parts of Alabama.

US: Tennessee Valley Shuts All Browns Ferry Nuclear Reactors After Storm

browns ferry nuclear reactor
Tennessee Valley Authority shut all three Browns Ferry reactors in Alabama yesterday after severe storms and tornadoes caused a brief power outage at the plant, Barbara Martocci, a company spokeswoman, said.

The plant, which includes the three reactors, automatically shut at 5:30 p.m. local time after losing the off-site power supply, Martocci, who is based in Knoxville, Tennessee, said today in a telephone interview.

Bad Science Propaganda: Iceland - Would an Eyjafjallajökull repeat eruption ground airplanes again?

The ash first emitted by Icelandic volcano Eyjafjallajökull when it erupted one year ago has been assessed as dangerous to airplanes and the resulting airport closures as justified, a study by earth scientist Sigurdur R. Gíslason of the University of Iceland says.

He studied the eruption with Susan Stipp from the University of Copenhagen and their findings indicate that any future eruption should be treated the same way until any ash clouds can be proven safe for aircraft.

"We demonstrated the ash had very fine particles and was carried long distances by air currents," Gíslason said.

Europe rebuked for supplying false volcano ash info to air passengers

Airport terminal
Thousands of flights were grounded in last year's ash alert
The European Ombudsman, P. Nikiforos Diamandouros, has criticised the misleading information given to air passengers by the European Commission during the volcanic ash crisis in 2010.

The official inquiry followed a complaint from the European Regions Airline Association about, among others, inaccurate information concerning compensation for delayed luggage.

The Ombudsman asked the Commission to inform him by 31 May 2011 of the measures taken to prevent such a problem from occurring in the future.

At least 250 dead as hundreds of tornadoes devastate Southern US

Pleasant Grove, Alabama - Dozens of massive tornadoes tore a town-flattening streak across the South, killing at least 250 people in six states and forcing rescuers to carry some survivors out on makeshift stretchers of splintered debris. Two of Alabama's major cities were among the places devastated by the deadliest twister outbreak in nearly 40 years.

As day broke Thursday, people in hard-hit areas surveyed obliterated homes and debris-strewn streets. Some told of deadly winds whipping through within seconds of weather alerts broadcast during the storms Wednesday afternoon and evening.

"It happened so fast it was unbelievable," said Jerry Stewart, a 63-year-old retired firefighter who was picking through the remains of his son's wrecked home in Pleasant Grove, a suburb of Birmingham. "They said the storm was in Tuscaloosa and it would be here in 15 minutes. And before I knew it, it was here."

Record number of whales, krill found in Antarctic bays

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula.

The sightings, made in waters still largely ice-free deep into austral autumn, suggest the previously little-studied bays are important late-season foraging grounds for the endangered whales. But they also highlight how rapid climate change is affecting the region.

The Duke University-led team tracked the super-aggregation of krill and whales during a six-week expedition to Wilhelmina Bay and surrounding waters in May 2009. They published their findings today (April 27) in the online science journal PLoS ONE.

"Such an incredibly dense aggregation of whales and krill has never been seen before in this area at this time of year," says Duke marine biologist Douglas Nowacek. Most studies have focused on whale foraging habitats located in waters farther offshore in austral summer.
