YA'AN, China -- Residents huddled outdoors Saturday night in a town near the epicenter of a powerful earthquake that struck the steep hills of China's southwestern Sichuan province, leaving at least 156 people dead and more than 5,500 injured.

Saturday morning's earthquake triggered landslides and disrupted phone and power connections in mountainous Lushan county five years after a devastating quake wreaked widespread damage across the region. The village of Longmen was hit particularly hard, with authorities saying nearly all the buildings there had been destroyed in a frightening minute-long shaking by the quake.

In nearby Ya'an town, where aftershocks could be felt nearly 20 hours after the quake, residents sat in groups outside convenience stores watching the news on television sets. Fourteen-year-old Wang Xing sat with her family on chairs by the roadside in the cool night air, a large blanket on her lap.

Wang and her relatives said they planned to spend the night in their cars. "We don't feel safe sleeping at home tonight," said Wang, a student. She said the quake left tears on the walls of her family's house. "It was very scary when it happened. I ran out of my bed and out of the house. I didn't even have my shoes on."

Along the main roads leading to the worst-hit county of Lushan, ambulances, fire engines and military trucks piled high with supplies waited in long lines, some turning back to try other routes when roads were impassable.





Rescuers turned the square outside the Lushan County Hospital into a triage center, where medical personnel bandaged bleeding victims, according to footage on China Central Television. Rescuers dynamited boulders that had fallen across roads to reach Longmen and other damaged areas lying farther up the mountain valleys, state media reported.

The China Earthquake Administration said at least 156 people had died, including 96 in Lushan. In the jurisdiction of Ya'an, which administers Lushan, 19 people were reported missing and more than 5,500 people were injured, the administration said.

The quake - measured by the earthquake administration at magnitude-7.0 and by the U.S. Geological Survey at 6.6 - struck the steep hills of Lushan county shortly after 8 a.m., when many people were at home, sleeping or having breakfast. People in their underwear and wrapped in blankets ran into the streets of Ya'an and even the provincial capital of Chengdu, 115 kilometers (70 miles) east of Lushan, according to photos, video and accounts posted online.

The quake's shallow depth, less than 13 kilometers (8 miles), likely magnified the impact.

Chengdu's airport shut down for about an hour before reopening, though many flights were canceled or delayed, and its railway station halted dozens of scheduled trains, state media said.

Lushan reported the most deaths, but there was concern that casualties in neighboring Baoxing county might have been under-reported because of inaccessibility after roads were blocked and power and phone services cut off.

As the region went into the first night after the quake, rain started to fall, slowing rescue work. Forecasts called for more rain in the next several days, and the China Meteorological Administration warned of possible landslides and other geological disasters.

Tens of thousands of people moved into tents or cars, unable to return home or too afraid to go back as aftershocks continued to jolt the region.

Lushan, where the quake struck, lies where the fertile Sichuan plain meets foothills that eventually rise to the Tibetan plateau and sits atop the Longmenshan fault. It was along that fault line that a devastating magnitude-7.9 quake struck on May 12, 2008, leaving more than 90,000 people dead or missing and presumed dead in one of the worst natural disasters to strike China in recent decades.

"It was just like May 12," Liu Xi, a writer in Ya'an city, who was jolted awake by Saturday's quake, said via a private message on his account on Sina Corporation's Twitter-like Weibo service. "All the home decorations fell at once, and the old house cracked."

The official Xinhua News Agency said the well-known Bifengxia panda preserve, which is near Lushan, was not affected by the quake. Dozens of pandas were moved to Bifengxia from another preserve, Wolong, after its habitat was wrecked by the 2008 quake.

As in most natural disasters, the government mobilized thousands of soldiers and others - 7,000 people by Saturday afternoon - sending excavators and other heavy machinery as well as tents, blankets and other emergency supplies. Two soldiers died after the vehicle that they and more than a dozen others were in slipped off the road and rolled down a cliff, state media reported.

Premier Li Keqiang flew to Ya'an to direct rescue efforts, and he and President Xi Jinping ordered officials and rescuers to make saving people the top priority, Xinhua said.

The Chinese Red Cross said it had deployed relief teams with supplies of food, water, medicine and rescue equipment to the disaster areas.

With roads blocked for several hours after the quake, the military surveyed the disaster area by air. Aerial photos released by the military and shown on state television showed individual houses in ruins in Lushan and outlying villages flattened into rubble. The roofs of some taller buildings appeared to have slipped off, exposing the floors beneath them.

A person whose posts to the micro-blogging account "Qingyi Riverside" on Weibo carried a locator geotag for Lushan said many buildings collapsed and that people could spot helicopters hovering above.

The earthquake administration said there had been at least 712 aftershocks, including two of magnitude-5.0 or higher.

"It's too dangerous," said a person with the Weibo account Chengduxinglin and with a Lushan geotag. "Even the aftershocks are scary."

While rescuers and state media rushed to the disaster scene, China's active social media users filled the information gap. They posted photos of people fleeing to streets for safety and of buildings flattened by the quake. They shared information on the availability of phone services, apparently through data services.

Associated Press writer Didi Tang contributed to this report from Beijing.

Earthquake Strikes Central Taiwan; One Dead, Some Factories Disrupted


03/27/2013| 05:23am US/Eastern


--Officials say collapsing wall kills one person

--TSMC says quake had "minimal impact" on production

(Recasts first paragraph to update with one person dead; adds new details of damage and factory disruptions throughout) By Aries Poon and Lorraine Luk


TAIPEI--An earthquake killed at least one person and disrupted operations at some electronics factories in central Taiwan on Wednesday morning, but the rest of the island was largely unscathed.

The Central Weather Bureau said that the magnitude 6.1 quake struck at 10:03 a.m. local time (0203 GMT) and was centered in Nantou County at a depth of 15.4 kilometers. Aftershocks as strong as magnitude 4.3 rattled the area for the next two and a half hours. The initial temblor shook buildings in the capital, Taipei, 120 kilometers to the north.

A collapsing wall killed a 72-year-old woman at a temple in Nantou County, the National Fire Agency said, adding that 19 other people across central Taiwan were injured, mostly by falling objects. The injured included one person struck by a section of ceiling at a government office in Nantou County, the fire agency said.

Taiwan Semiconductor Manufacturing Co. (>> Taiwan Semiconductor Mfg. Co. Ltd.), the world's largest contract chip maker by revenue, evacuated two of its factories in central and northern Taiwan after the earthquake. But a spokesman for the Hsinchu-based company said that employees had gone back to work and that the quake had a "minimal impact" on production.

TSMC added that it has an emergency mechanism that automatically orders employees to evacuate when an earthquake of magnitude 4 or greater is detected.

Flat-panel maker AU Optronics Cop. (>> AU Optronics Corp.) said Wednesday afternoon that operations at some of its facilities in central Taiwan remained suspended after halting because of the quake. Innolux Corp. (>> Innolux Corp) said that its production was unaffected.

At The Wall Street Journal's Taipei office the quake was felt for at least 15 seconds, shaking the ceiling violently enough that it squeaked.

Television footage showed large boulders littering roads in central Taiwan, as well as books scattered on the floor of a public library and home interiors sprinkled with broken glass, fallen wall tiles and other debris.

Taiwan lies near the junction of two tectonic plates and is frequently hit by earthquakes. The last major quake--a magnitude 7.6 temblor that killed more than 2,000 people--struck in 1999 and was also centered in Nantou County.

Earthquake, aftershocks felt across Oklahoma, region

Multiple earthquakes shook much of central Oklahoma early Saturday, rousing people from their sleep as far away as Kansas City, Mo.

FROM STAFF REPORTS
Published: November 5, 2011

A 4.7 magnitude earthquake rattled homes across central Oklahoma early Saturday morning.

The U.S. Geological Survey said the initial quake was centered about six miles north of Prague about 2:12 a.m.

That quake was followed by a series of aftershocks. A 3.4 magnitude aftershock was felt moments later followed by another 2.7 magnitude aftershock about five miles southeast of Sparks. Sparks is east of the metro area in Lincoln County.

And those aftershocks continued into this morning as a 3.6 magnitude quake struck about 8:36 a.m., also centered about two miles southeast of Sparks.

The National Weather Service in Norman said via its Facebook page the earthquake was felt in Norman and also as far away as weather offices in Topeka, Kansas and Pleasant Hill, Missouri.

There have been no reports of significant damage caused by the quake. According to OG&E's system watch page it did not cause power outages anywhere in that company's coverage area across the state. Oklahoma Natural Gas is not reporting any gas leaks or service outages.

Tom Foster was awakened in his southwest Oklahoma City home by what he believes was an aftershock.

"It was a little later than what they say was the initial quake so I think I felt one of the after shocks," he said. "The bigger quake didn't wake me up. But I know we've already had several phone calls from out of state relatives wondering what happened. I guess it's more interesting than anything that was dangerous."

Heather Spicer of Sapulpa said the quake woke her son and dog up.
"At first I thought and airplane had crashed nearby," she said. "But now I believe it was an earthquake because the whole house just kept vibrating with what sounded like distant thunder outside."

Matt Hoover of Perkins was wrapping birthday presents at 2:20 a.m. when he felt the quake. He thought the experience, his first with a quake, was exciting.

"The whole house started to shake and a low rumble could be heard throughout the house," he said. "It lasted about 20 seconds."

300 dead in Tibetan quake

8,000 reportedly injured



By Jamie L. Slaten - Morning News Producer

Wednesday, April 14, 2010 - 2:17am
A magnitude 6.9 earthquake killed at least 300 people in China's mountainous Tibetan Plateau Tuesday.

Rescue workers say dozens more are trapped in collapsed houses in the ethnic Tibetan Region and nearly 8,000 people were injured.

China's official news agency reported this morning that a series of quakes and aftershocks caused low level brick buildings to collapse.

The quake was centered in the mountains that divide China's Qinghai Province from the Tibet Autonomous Region.

The foothills to the South and East of the area are home to herders and Tibetan monasteries.

Major Aftershock Jolts Chile

SANTIAGO, Chile — At least three major aftershocks rocked central Chile on Thursday, striking minutes before its president-elect was sworn into office to take charge of a country still reeling from a devastating earthquake nearly two weeks ago.

Chile’s Navy rapidly issued a tsunami alert, and Chilean television carried reports of residents of coastal areas fleeing for higher ground. There were no immediate reports of damage, but in the capital of Santiago, 95 miles north of the epicenters, windows rattled, buildings trembled and cell phone service went down.

In the coastal city of Valparaiso, about 90 miles from the site of Thursday’s earthquakes, dignitaries who gathered for the inauguration of President Sebastián Piñera made nervous jokes and glanced at the shuddering ceiling of the National Congress building as the quakes hit, according to news reports.

Mr. Piñera, however, showed no sign of acknowledging the tremors, and continued to shake hands with leaders and supporters before taking the oath of office. But the building was evacuated after the inauguration.

The first of the three major aftershocks hit at 11:39 a.m., with a magnitude of 7.2. It the strongest to hit since Chile was ravaged by an 8.8-magnitude quake on Feb. 27.

The United States Geological Survey reported that the quake struck the coast near the city of Rancagua, and was quickly followed by one of 6.9 magnitude at 11:55 a.m., and another of 6.0 magnitude at 12:06 p.m.Scores of strong aftershocks have rattled Chile’s interior and its coastline since one of the most powerful earthquakes on record, at magnitude 8.9, devastated the country on Feb. 27. That quake killed hundreds of people, toppled apartment buildings and bridges, and stirred up powerful waves that wiped away entire fishing villages as they pounded the southern coast of the country.

The United States Geological Survey also reported that two other shocks, with magnitudes of about 5.0, hit the central part of Chile and its south earlier Thursday.

Earthquake shakes eastern Turkey


37 mins ago



ANKARA, Turkey – An official says at least five people have died in a strong earthquake that hit the eastern province of Elazig.

Gov. Muammer Erol says the victims are from the small village of Okcular.

The Istanbul-based Kandilli Observatory says the quake occurred at 4:32 a.m. (0232 GMT) Monday. It was followed by an aftershock measuring 4.1.

Earthquakes are frequent in Turkey, much of which lies atop the North Anatolian fault.

In 1999, two powerful earthquakes struck northwestern Turkey, killing about 18,000 people.

Jamaica Shares Same Earthquake Faultline as Haiti

Office of the Prime Minister

Wednesday, January 20, 2010



Head of the Earthquake Unit at the University of the West Indies, Dr. Lyndon Brown, left, speaking at a Think Tank at JIS head office, Kingston,on Wednesday, January 20, 2010. At Right is Director General of the Office of Disaster Preparedness and Emergency Management (ODPEM), Ronald Jackson.


Jamaica shares the same fault line (a crack or break in the earth's surface) with Haiti, which suffered a devastating 7.0 magnitude earthquake on January 11.

This was disclosed by the Head of the Earthquake Unit of the University of the West Indies (UWI), Dr. Lyndon Brown, at a JIS Think Tank in Kingston on January 20.

"The fault that created the quake in Haiti runs right across the western end of the Dominican Republic, through Haiti, cuts across the Caribbean Sea into Jamaica and continues more or less into different fault lines across Jamaica: one continuous fault line runs across from Haiti to Jamaica," Dr. Brown stated.

He added that the activities in the region, following the Haiti earthquake, are not unusual, at this time.

"A number of aftershocks have taken place, and this is quite natural. The aftershocks will be more continuous after the large earthquake, but then this will die down and become less frequent," he said. Aftershocks, such as the magnitude 6.1 tremor that occurred in Haiti again on the Wednesday morning (January 20), can be large but will become less frequent over time.

He said, however, that the other earthquakes that have taken place in Guatemala, Venezuela, and El Salvador are happening on the Pacific Plate fault line, which is not the same one on which Haiti and Jamaica is located.

"Right now we do not see the association between the events," he added.

He said that while studies are being done by an American researcher, to see the relationships between the fault lines, none has so far been established, and what is happening is that stresses are being naturally released along respective fault lines.

"Earthquakes are very, very, common. If you look at a map of Jamaica you will see that last year we had about eight felt events (earthquakes) and about 200 that were weak but could just be picked up as earthquakes," he said.

He stated that, on average, there have been about16 earthquakes on an annual basis that are greater that magnitude 7.0 , about 120 around magnitude 6.0 and an innumerable amount at magnitude 5.0 and below.

"What is happening in the region is very interesting. Earthquakes are natural events that happen when stresses that have built up along fault lines are released, creating elastic waves that generate convolutions on the face of the earth," Dr. Brown said.

He added that the destruction wrought by an earthquake is dependent on the location and strength of a building, as well as the strength of the earthquake.

Magnitude-6.1 aftershock in Haiti - Update

Posted : Wed, 20 Jan 2010 12:09:47 GMT
By : dpa

Port-au-Prince, Haiti - A strong aftershock struck Haiti on Wednesday, a week after a 7.0-magnitude earthquake that may have killed up to 200,000 people in the Caribbean nation. The US Geological Survey (USGS) said the 6.1-magnitude tremblor struck at 1103 GMT, with its epicentre some 60 kilometres west of the capital. Its depth was recorded at 9.9 kilometres.

The aftershock was felt in the capital Port-au-Prince. There were no immediate reports of casualties or damage.

The aftershock comes as international aid efforts are in full swing in Haiti, one of the world's poorest and most troubled nations.

Some estimates have put the death toll at up to 200,000 people from the initial quake.

USGS scientists have measured dozens of aftershocks since the devastating earthquake, including two that followed within the hour, measuring 5.9 and 5.5 on the Richter scale.

The quake struck at 4:53 pm (2153 GMT) last Tuesday, some 15 kilometres south-west of the city at a depth of 10 kilometres.
