Volcano erupts near Eyjafjallajoekull in south Iceland

An Icelandic volcano, dormant for 200 years, has erupted, ripping a 1km-long fissure in a field of ice.

The volcano near Eyjafjallajoekull glacier began to erupt just after midnight, sending lava a hundred metres high.

Icelandic airspace has been closed, flights diverted and roads closed. The eruption was about 120km (75 miles) east of the capital, Reykjavik.

About 500 people were moved from the area, a civil protection officer said.

“We estimate that no-one is in danger in the area, but we have started an evacuation plan and between 500 and 600 people are being evacuated,” Sigurgeir Gudmundsson of the Icelandic civil protections department told the Agence France-Presse news agency.

The area is sparsely populated, but the knock-on effects from the eruption have been considerable.

A state of emergency is in force in southern Iceland and transport connections have been severely disrupted, including the main east-west road.

“Ash has already begun to fall in Fljotshlid and people in the surrounding area have reported seeing bright lights emanating from the glacier,” RUV public radio said on its website.

“It was a bit scary, but still amazing to see,” Katrin Moller Eiriksdottir, who lives in Fljotshlid, told the BBC News website.

“The ash had started falling and we couldn’t leave the car.”

Three Icelandair flights, bound for Reykjavik from the United States, were ordered to return to Boston, RUV radio reported.

Domestic flights were suspended indefinitely, but some international flights were scheduled to depart on Sunday.

There had initially been fears that the volcano could cause flooding, as it causes ice to melt on the glacier above it, but that scenario appears to have been avoided.

However, it could cause more activity nearby, scientists say.

“This was a rather small and peaceful eruption but we are concerned that it could trigger an eruption at the nearby Katla volcano, a vicious volcano that could cause both local and global damage,” said Pall Einarsson, a geophysicist at the University of Iceland’s Institute of Earth Science, Associated Press news agency reported.

As the eruption is taking place in an area that is relatively ice free, there is little chance of a destructive glacier burst like the one that washed away part of the east-west highway four years ago, after an eruption under the vast Vattnajoekull glacier.

Iceland lies on the Mid-Atlantic Ridge, the highly volatile boundary between the Eurasian and North American continental plates, with quakes and eruptions.

The last volcanic eruption in the Eyjafjallajoekull area occurred in 1821.

Strong earthquake hits eastern Turkey

The injured were ferried to hospital with the help of relatives

A strong earthquake has struck eastern Turkey, killing at least 57 people, officials have said.

The 6.0-magnitude quake, centred on the village of Basyurt in Elazig province, struck at 0432 (0232 GMT). It has been followed by more than 40 aftershocks.

Officials said the nearby village of Okcular had been almost destroyed and several others badly damaged.

A number of people were trapped in the rubble of collapsed buildings, many of which were built of mud-bricks.

“Villages consisting mainly of mud-brick houses have been damaged, but we have minimal damage such as cracks in buildings made of cement or stone,” Elazig Governor Muammer Erol told CNN Turk.

Everything has been knocked down – there is not a stone in place Yadin Apaydin Administrator for Yukari Kanatli.

At least 17 of the dead came from the hillside village of Okcular, where up to 30 houses collapsed, rescuers said.

“The village is totally flattened,” Okcular’s administrator, Hasan Demirdag, told NTV.

Television footage from Okcular showed rescue workers and soldiers digging among the rubble of collapsed buildings as villagers looked on.

Ali Riza Ferhat, a resident, said he had been asleep in his home when the earthquake struck.

“I tried to get out of the door but it wouldn’t open. I came out of the window and started helping my neighbours,” he told NTV. “We removed six bodies.”

The nearby villages of Yukari Kanatli, Kayalik, Gocmezler and Yukari Demirci were also badly damaged and each reported several deaths.

“Everything has been knocked down – there is not a stone in place,” Yadin Apaydin, the administrator for Yukari Kanatli, told CNN Turk.

At least 50 people have been taken to hospital, officials say. Some were reportedly hurt during the panic after the first earthquake, when they jumped from windows or balconies.

Residents of the affected villages have been warned not to return to damaged homes while the area continues to be hit by aftershocks, the strongest of which have so far measured 5.1 and 5.5.

The government disaster management centre and Turkish Red Crescent have set up tents to help survivors cope with the harsh winter weather, and are also distributing food and blankets.

Deputy Prime Minister Cemil Cicek and three other ministers have travelled to the earthquake zone to provide assistance.

We’ve experienced so many earthquakes in the last 20 years, yet no measures have been taken to strengthen the buildings
Volkan Durkal

In Ankara, Prime Minister Recep Tayyip Erdogan lamented the lack of earthquake-safe buildings and said he had ordered the start of a reconstruction project in the area.

“Mud-brick construction is undoubtedly a local tradition. But unfortunately, it has proved to have a heavy price,” he said.

A BBC News website reader who visited the village of Basyurt after the earthquake said its residents blamed the government for the destruction and loss of life.

“This is a seismic area. We’ve experienced so many earthquakes in the last 20 years, yet no measures have been taken to strengthen the buildings,” Volkan Durkal said.

“Most houses are not made with cement, they are not well-built and the people are not well-educated about what to do and where to take cover during an earthquake.”

Turkey is plagued by earthquakes – generally minor – because of its location on the North Anatolian fault line.

A 7.4-magnitude tremor which hit the western city of Izmit in August 1999 killed more than 17,000 people.

The BBC’s Jonathan Head in Istanbul says poor quality buildings were also blamed for the high death toll then and there is still concern in Turkey’s largest city, where seismologists predict a major earthquake will occur within the next few decades.

Tsunami swept away fleeing bus full of retirees

Mar 2, 7:10 AM (ET)

By MICHAEL WARREN and EVA VERGARA

PELLUHUE, Chile (AP) – The 40 retirees enjoying summer vacation at a seaside campground nestled under pine trees knew they had to move fast after Chile’s powerful earthquake struck.

They didn’t make it. The tsunami came in three waves, surging 200 meters (yards) into this Pacific Ocean resort town and dragging away the bus they’d piled into, hoping to get to high ground. Most of those inside were tourists, and only five of their bodies had been found by Monday, firefighters and witnesses said.

Pelluhue’s horror underscored the destruction wrought by Saturday’s pre-dawn 8.8-magnitude quake and the tsunami that ravaged communities along Chile’s south-central coast – those closest to the quake’s epicenter. Chile’s death toll reached 723, and most died in the wine-growing Maule region that includes Pelluhue.

Survivors here found about 20 bodies, and an estimated 300 homes were destroyed. Most residents were aware of the tsunami threat; street signs pointed to the nearest tsunami evacuation route. The ruins of homes, television sets, clothes, dishwaters and dead fish cover the town’s black sand beaches.

“We ran through the highest part of town, yelling, ‘Get out of your homes!’” said Claudio Escalona, 43, who fled his home near the campground with his wife and daughters, ages 4 and 6. “About 20 minutes later came three waves, two of them huge, about 6 meters (18 feet) each, and a third even bigger. That one went into everything.”

“You could hear the screams of children, women, everyone,” Escalona said. “There were the screams, and then a tremendous silence.”

Destruction is widespread and food scarce all along the coast – in towns like Talca and Cauquenes, Curico and San Javier. In Curanipe, the local church served as a morgue. In Cauquenes, people quickly buried their dead because the funeral home had no electricity.

President Michelle Bachelet said authorities were flying hundreds of tons of food, water and other basics into the region.

After the quake rocked the gritty port town of Talcahuano, Marioli Gatica and her extended family huddled in a circle on the floor of their seaside wooden home, listening to the radio by a lantern’s light.

They heard firefighters urging citizens to stay calm and stay inside. They heard nothing about a tsunami – until it slammed into their house with an unearthly roar. Gatica’s house exploded with water. The family was swept below the surface, swirling amid loose ship containers and other heavy debris that smashed buildings into oblivion all around them.

“We were sitting there one moment and the next I looked up into the water and saw cables and furniture floating,” Gatica said.

Two of the giant containers crushed Gatica’s home. A third grounded between the ocean and where she floated, keeping the retreating tsunami from dragging her and other relatives out to sea. Her 11-year-old daughter, Ninoska Elgueta, clung to a tree as the wave retreated.

All the family survived except Gatica’s 76-year-old mother, Nery Valdebenito, Gatica said. “I think my mother is trapped beneath” the house.

Firefighters with search dogs examined the ruins of her home. The group leader drew his finger across his neck: No one alive there.

Close to 80 percent of Talcahuano’s 180,000 people are homeless, with 10,000 homes uninhabitable and hundreds more destroyed, Mayor Gaston Saavedra said.

“The port is destroyed. The streets, collapsed. City buildings, destroyed,” Saavedra said.

In Concepcion, the biggest city near the epicenter, rescuers who had paused in a search for survivors resumed their hunt on Tuesday at a toppled 70-unit apartment building. Firefighters had pulled 25 survivors and nine bodies from the structure.

Chile’s defense minister has said the navy made a mistake by not immediately activating a tsunami warning. He said port captains who did call warnings in several coastal towns saved hundreds of lives.

In the village of Dichato, teenagers drinking on the beach were the first to shout the warning when they saw a horseshoe-shaped bay empty about an hour after the quake. They ran through the streets, screaming. Police joined them, using megaphones.

The water rose steadily, surging above the second floors of homes and lifting them off their foundations. Cars were stacked three high in the streets. Miles inland along a river valley, cows munched next to marooned boats, refrigerators, sofas and other debris.

“The maritime radio said there wouldn’t be a tsunami,” said Rogilio Reyes, who was warned off by the teenagers.

Dichato Mayor Eduardo Aguilera said 49 people were missing and 800 homes were destroyed. Some people fled to high ground, only to return too early and get caught by the tsunami, he said.

The World Health Organization said it expected the death toll to rise as communications improve. For survivors, it said access to health services will be a major challenge.

In Geneva, U.N. humanitarian spokeswoman Elisabeth Byrs said Chile was seeking temporary bridges, field hospitals, satellite phones, electric generators, damage assessment teams, water purification systems, field kitchens and dialysis centers.

U.S. Secretary of State Hillary Rodham Clinton said she was bringing 20 satellite phones Tuesday as a first piece of a much larger U.S. aid package. Argentina was sending six aircraft carrying a field hospital, 55 doctors and water treatment plants – all of which should arrive by Tuesday night. Brazil was rushing in a field hospital and rescue teams.

Security remained a concern. Most markets in Concepcion were ransacked by looters and people desperate for food, water, toilet paper, gasoline and other essentials Sunday, prompting authorities to send troops and impose an overnight curfew. The interior ministry extended the city curfew to run from 8 p.m. Monday to noon Tuesday.

When a small convoy of armored vehicles drove along a downtown street, bystanders applauded, shouting: “Finally! Finally!”

Chilean Quake Likely Shifted Earth’s Axis, NASA Scientist Says

By Alex Morales

March 1 (Bloomberg) — The earthquake that killed more than 700 people in Chile on Feb. 27 probably shifted the Earth’s axis and shortened the day, a National Aeronautics and Space Administration scientist said.

Earthquakes can involve shifting hundreds of kilometers of rock by several meters, changing the distribution of mass on the planet. This affects the Earth’s rotation, said Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects.

“The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second),” Gross, said today in an e-mailed reply to questions. “The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches).”

The changes can be modeled, though they’re difficult to physically detect given their small size, Gross said. Some changes may be more obvious, and islands may have shifted, according to Andreas Rietbrock, a professor of Earth Sciences at the U.K.’s Liverpool University who has studied the area impacted, though not since the latest temblor.

Santa Maria Island off the coast near Concepcion, Chile’s second-largest city, may have been raised 2 meters (6 feet) as a result of the latest quake, Rietbrock said today in a telephone interview. He said the rocks there show evidence pointing to past earthquakes shifting the island upward in the past.

‘Ice-Skater Effect’

“It’s what we call the ice-skater effect,” David Kerridge, head of Earth hazards and systems at the British Geological Survey in Edinburgh, said today in a telephone interview. “As the ice skater puts when she’s going around in a circle, and she pulls her arms in, she gets faster and faster. It’s the same idea with the Earth going around if you change the distribution of mass, the rotation rate changes.”

Rietbrock said he hasn’t been able to get in touch with seismologists in Concepcion to discuss the quake, which registered 8.8 on the Richter scale.

“What definitely the earthquake has done is made the Earth ring like a bell,” Rietbrock said.

The magnitude 9.1 Sumatran in 2004 that generated an Indian Ocean tsunami shortened the day by 6.8 microseconds and shifted the axis by about 2.3 milliarcseconds, Gross said.

The changes happen on the day and then carry on “forever,” Benjamin Fong Chao, dean of Earth Sciences of the National Central University in Taiwan, said in an e-mail.

“This small contribution is buried in larger changes due to other causes, such as atmospheric mass moving around on Earth,” Chao said.
