Chile volcano ash grounds flights in Argentina

Posted by Admin on June 7, 2011

By MICHAEL WARREN, Associated Press 20 mins ago

BUENOS AIRES, Argentina – Stiff winds blew ash from a Chilean volcano Tuesday in a widening arc across Argentina to the capital, grounding most air travel to and from the country.

Since airborne ash can severely damage jet engines, Aerolineas Argentinas and Austral, the country’s state-owned international and domestic airlines, canceled all flights within Argentina as well as to and from other countries until further notice.

At least six international carriers also suspended flights through Wednesday between Buenos Aires and cities in the United States, Europe and South America. Other carriers were expected to follow. Flights from Chile over Argentine territory also were suspended.

The capital’s usually bustling international and domestic airports were nearly deserted Tuesday, and aviation regulators met to decide whether and for how long to close them. Geologists in Chile have said the Cordon Caulle volcano could keep erupting for several weeks.

The closest major city to the volcano is San Carlos de Bariloche, just over the border in Argentina, where thick abrasive soot was coating slopes in a string of resorts that depend on the winter ski season, opening in less than two weeks. The plume then stretched northeast before curving east, dumping ash over Argentina’s vast ranchlands before reaching the capital.

“Given that even this morning the volcano continues to be active, the reopening of the airports isn’t expected until the conditions necessary for security can be guaranteed,” Argentina’s transportation department announced.

Transportation officials were meeting with representatives of Argentina’s meteorological service, civil aviation board and airport regulator to figure out where the ash cloud will move next and what to do about it, the statement said.

Despite the complications to air travel, the ash couldn’t be seen in the streets of downtown Buenos Aires by midday Tuesday.

But Jorge Echarran, who runs the emergency council of the surrounding Buenos Aires province, said in a local radio interview that “the cloud is already in the suburbs and is reaching the capital,” hovering at an altitude of between 16,400 feet (5,000 meters) and 22,970 feet (7,000 meters).

The ash cloud was blowing well to the south and away from Chile’s capital, Santiago, but at least four international carriers there canceled flights across Argentina to Buenos Aires, Brazil, Uruguay and Europe as a precaution.

Closer to the volcano, strong rains that began Monday night increased the danger of rivers getting clogged with ash and then overflowing in flash floods. Evacuations were expanding, with more than 4,000 people already fleeing their homes.

Vulcanologist Jorge Munoz of Chile’s National Geology and Mines Service said the eruption so far is considered to be moderate, but that could change. He said the volcano will likely begin to expel lava in the coming days, along with pyroclastic material that can turn waterways into avalanches of mud and rock that have the potential to destroy downstream communities.

Chile Earthquake May Have Shortened Days on Earth

Chile Earthquake May Have Shortened Days on Earth
By SPACE.com Staff

This story was updated at 6:22 p.m. EST.

The massive 8.8 earthquake that struck Chile may have changed the entire Earth’s rotation and shortened the length of days on our planet, a NASA scientist said Monday.

The quake, the seventh strongest earthquake in recorded history, hit Chile Saturday and should have shortened the length of an Earth day by 1.26 microseconds, according to research scientist Richard Gross at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. One microsecond is one-millionth of a second long.

“This change should be permanent,” Gross told SPACE.com today. There is a chance the Earth’s rotation could relax over time, but it is too early to tell, he said.

The computer model used by Gross and his colleagues to determine the effects of theChile earthquake effect also found that it should have moved Earth’s figure axis by about 3 inches (8 cm or 27 milliarcseconds).

“Perhaps more impressive is how much the quake shifted Earth’s axis,” NASA officials said in a Monday update.

The Earth’s figure axis is not the same as its north-south axis, which it spins around once every day at a speed of about 1,000 mph (1,604 kph).

The figure axis is the axis around which the Earth’s mass is balanced. It is offset from the Earth’s north-south axis by about 33 feet (10 meters).

Strong earthquakes have altered Earth’s days and its axis in the past. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami, should have shortened Earth’s days by 6.8 microseconds and shifted its axis by about 2.76 inches (7 cm, or 2.32 milliarcseconds).

One Earth day is about 24 hours, or 86,400 seconds, long. Over the course of a year, the length of a day normally changes gradually by about one millisecond, which is 1,000 microseconds.

That variation is due to seasonal variations in the Earth’s ocean currents and the atmosphere’s jet stream, Gross said. As the jet stream shifts southward during the winter months in the Earth’s northern hemisphere, the length of the day gradually changes, he said.

In the past, Gross has said that Earth’s rotation slows down slightly in those winter months, then picks back up in the summer.

The Chile earthquake was much smaller than the Sumatran temblor, but its effects on the Earth still have an impact because of its location. Its epicenter was located in the Earth’s mid-latitudes rather than near the equator like the Sumatran event.

Gross compared the Sumatran event to a figure skater drawing her arms inward during a spin to turn faster on the ice. Since the Sumatran quake was closer to the Earth’s equator, its day-shortening effect is stronger than the Chile temblor, he said.

But the fault responsible for the 2010 Chile quake also slices through Earth at a steeper angle than the Sumatran quake’s fault, NASA scientists said.

“This makes the Chile fault more effective in moving Earth’s mass vertically and hence more effective in shifting Earth’s figure axis,” NASA officials said.

Gross said his findings are based on early data available on the Chile earthquake. He is confident in the computer model’s accuracy, with only slight tweaks expected to be required, he said.

The Chile earthquake has killed more than 700 people and caused widespread devastation in the South American country.

Several major telescopes in Chile’s Atacama Desert have escaped damage, according to the European Southern Observatory managing them.

A salt-measuring NASA satellite instrument destined to be installed on an Argentinean satellite was also undamaged in the earthquake, JPL officials said.

The Aquarius instrument was in the city of Bariloche, Argentina, where it is being installed in the Satelite de AplicacionesCientificas (SAC-D) satellite. The satellite integration facility is about 365 miles (588 km) from the Chile quake’s epicenter.

The Aquarius instrument is designed to provide monthly global maps of the ocean’s salt concentration in order to track current circulation and its role in climate change.

Huge quake hits Chile – Tsunami threatens Pacific

Huge quake hits Chile – Tsunami threatens Pacific

By ROBERTO CANDIA and EVA VERGARA, Associated Press Writer – 58 mins ago

TALCA, Chile – A devastating earthquake struck Chile early Saturday, toppling homes, collapsing bridges and plunging trucks into the fractured earth. A tsunami set off by the magnitude-8.8 quake threatened every nation around the Pacific Ocean — roughly a quarter of the globe.

Interior Minister Edmundo Perez Yoma said the most powerful quake to hit the country in a half-century killed at least 82 people, but the death toll was rising quickly.

In the town of Talca, just 65 miles (105 kilometers) from the epicenter, Associated Press journalist Roberto Candia said it felt as if a giant had grabbed him and shaken him.

The town’s historic center, filled with buildings of adobe mud and straw, largely collapsed, though most of those were businesses that were not inhabited during the 3:34 a.m. (1:34 a.m. EST, 0634 GMT) quake. Neighbors pulled at least five people from the rubble while emergency workers, themselves disoriented, asked for information from reporters.

Many roads were destroyed, and electricity, water and phone lines were cut to many areas — meaning there was no word of death or damage from many outlying areas.

In the Chilean capital of Santiago, 200 miles (325 kilometers) northeast of the epicenter, a car dangled from a collapsed overpass, the national Fine Arts Museum was badly damaged and an apartment building’s two-story parking lot pancaked, smashing about 50 cars whose alarms rang incessantly.

Experts warned that a tsunami could strike anywhere in the Pacific, and Hawaii could face its largest waves since 1964 starting at 11:19 a.m. (4:19 p.m. EST, 2119 GMT), according to Charles McCreery, director of the Pacific Tsunami Warning Center.

Tsunami waves were likely to hit Asian, Australian and New Zealandshores within 24 hours of the earthquake. The U.S. West Coast andAlaska, too, were threatened.

A huge wave swept into a populated area in the Robinson Crusoe Islands, 410 miles (660 kilometers) off the Chilean coast, PresidentMichelle Bachelet said, but there were no immediate reports of major damage.

Bachelet had no information on the number of people injured. She declared a “state of catastrophe” in central Chile.

“We have had a huge earthquake, with some aftershocks,” she said from an emergency response center. She said Chile has not asked for assistance from other countries, and urged Chileans not to panic.

“The system is functioning. People should remain calm. We’re doing everything we can with all the forces we have. Any information we will share immediately,” she said.

Powerful aftershocks rattled Chile’s coast — 24 of them magnitude 5 or greater and one reaching magnitude 6.9 — the U.S. Geological Survey reported.

In Santiago, modern buildings are built to withstand earthquakes, but many older ones were heavily damaged, including the Nuestra Senora de la Providencia church, whose bell tower collapsed. A bridge just outside the capital also collapsed, and at least one car flipped upside down.

Several hospitals were evacuated due to earthquake damage, Bachelet said.

Santiago’s airport will remain closed for at least 24 hours, airport director Eduardo del Canto said. The passenger terminal suffered major damage, he told Chilean television in a telephone interview. TV images show smashed windows, partially collapsed ceilings and pedestrian walkways destroyed.

Santiago’s subway was shut as well and hundreds of buses were trapped at a terminal by a damaged bridge, Transportation and Telecommunications Minister told Chilean television. He urged Chileans to make phone calls or travel only when absolutely necessary.

Candia was visiting his wife’s 92-year-old grandmother in Talca when the quake struck.

“Everything was falling — chests of drawers, everything,” he said. “I was sleeping with my 8-year-old sonDiego and I managed to cover his head with a pillow. It was like major turbulence on an airplane.”

In Concepcion, 70 miles (115 kilometers) from the epicenter, nurses and residents pushed the injured through the streets on stretchers. Others walked around in a daze wrapped in blankets, some carrying infants in their arms.

Concepcion, Chile’s second-largest city, is 60 miles (95 kilometers) from the ski town of Chillan, a gateway to Andean ski resorts that was destroyed in a 1939 earthquake.

The quake also shook buildings in Argentina‘s capital of Buenos Aires, 900 miles (1,400 kilometers) away on the Atlantic side of South America.

Marco Vidal, a program director for Grand Circle Travel who was traveling with a group of 34 Americans, was on the 19th floor of the Crown Plaza Santiago hotel when the quake struck.

“All the things start to fall. The lamps, everything, was going on the floor,” he said. “I felt terrified.”

Cynthia Iocono, from Linwood, Pennsylvania, said she first thought the quake was a train.

“But then I thought, `Oh, there’s no train here.’ And then the lamps flew off the dresser and my TV flew off onto the floor and crashed.”

The quake struck after concert-goers had left South America’s leading music festival in the coastal city of Vina del Mar, but it caught partiers leaving a disco.

“It was very bad. People were screaming. Some people were running, others appeared paralyzed. I was one of them,” Julio Alvarez told Radio Cooperativa.

The Pacific Tsunami Warning Center called for “urgent action to protect lives and property” in Hawaii, which is among 53 nations and territories subject to tsunami warnings.

“Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near theearthquake epicenter and could also be a threat to more distant coasts,” the warning center said. It did not expect a tsunami along the west of the U.S. or Canada.

The largest earthquake ever recorded struck the same area of Chile on May 22, 1960. The magnitude-9.5 quake killed 1,655 people and left 2 million homeless. The tsunami that it caused killed people in Hawaii,Japan and the Philippines and caused damage to the west coast of the United States.
