Pinera assumes Chile presidency presidency amid  7.2 strong quake

SANTIAGO, Chile – Chilean President Sebastian Pinera is urging citizens along the coast to move quickly to higher ground following five strongly felt aftershocks, including the biggest since last month's 8.8-magnitude temblor.

Chile's congress also was evacuated as a precautionary measure moments after Pinera was sworn in Thursday.

Aftershocks with preliminary magnitudes of 5.1, 7.2, 6.9 and 6.0, respectively, rocked Chile throughout the inauguration.

Pinera kept his cool but said Chileans shouldn't ignore the possibility of dangerous waves. The Chilean Navy issued a tsunami warning, but the U.S. Pacific Tsunami Warning Center said the aftershocks were too small to cause dangerous waves.

The 7.2 aftershock is the strongest yet. It was larger than Haiti's devastating magnitude-7 quake last month.

Magnitude 6.9 earthquake rocks Okinawa islands in southern Japan
 

TOKYO, Feb. 27 (Xinhua) -- An earthquake measuring 6.9 magnitude on the Richter scale on Saturday rocked Okinawa Prefecture and its vicinity in southern Japan, said the Japan Meteorological Agency.

The focus of the quake, which occurred at 5:31 a.m. local time (2031 GMT Friday), was located some 10 km under the sea 50 km east off Naha, capital of Okinawa, said the agency.

Two people, both female and aged 74 and 66, were reportedly slightly injured in the earthquake, local government reported.

The agency issued an warning of up to 2-meter high tsunami seismic waves for coastal regions of the main Okinawa island soon after the quake, but soon downgraded it to an advisory at about 6: 30 a.m., and later lifted it at around 7 a.m..

Small waves of up to around 10 centimeters reached Nanjo city on the island and Minamidaito village just before 6 a.m., the agency said.

MASSIVE 8.8-MAGNITUDE EARTHGUAKE STRIKES CHILE

February 26, 2010

SANTIAGO, Chile - A massive 8.8-magnitude earthquake struck Chile early Saturday, collapsing buildings, killing at least 16 people and downing phone lines. President Michele Bachelet declared a "state of catastrophe" in central Chile and said the death toll was rising.

Tsunami warnings were issued over a wide area, including South America, Hawaii, Australia and New Zealand, Japan, the Philippines, Russia and many Pacific islands.

"We have had a huge earthquake, with some aftershocks," Bachelet said, appealing from an emergency response center for Chileans to remain calm. "Despite this, 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." 

Is California Due for a Big Earthquake?

Small earthquakes in California ... tremors near the Philippines ... devastation in Haiti. Is the Earth in a period of increased seismic activity? And is the U.S. due for a big one? 

Small earthquakes in California ... tremors near the Philippines ... devastation in Haiti. Is the Earth in a period of increased seismic activity? And is the U.S. due for a big one?

A handful of quakes have shaken California over the past few weeks, ranging from smaller 4.4-magnitude shakers to a larger (and more recent) 6.5 quake off the Northern coast of the state. Californians have long lived uneasily in the presence of the San Andreas fault, the massive rift that runs the length of the state. But in light of the recent rumblings there and the dreadfully destructive quake in Haiti, many are worrying that the long-feared "Big One" on the West Coast may be just around the corner.

"Earthquake prediction has been something of a Holy Grail for the seismological community, and has proven just as elusive," says David Bowman, chairman of the department of geological sciences at California State University, Fullerton.

Every year there are approximately 150 earthquakes greater than magnitude 6, and 15-20 events above magnitude 7 somewhere in the world, Bowman said in an interview. Some can be as deep as 500 miles beneath the surface of the earth, and they are barely noticeable. 

But the 7.0 earthquake in Haiti this week was not only strong, it was also quite shallow -- just six miles underground, a factor that increased its destructive power. The quake's center was a few miles southwest of the well-populated capital, Port-au-Prince, which is along a 60-mile stretch of the Enriquillo-Plantain Garden Fault. That fault line runs east-west and reaches as far as Jamaica.

A shifting tectonic plate -- massive segments of the Earth's crust -- lies just south of Haiti. The Caribbean Plate slowly slides eastward. Further north, the North American Plate moves in the opposite direction. Stress builds up slowly as the two plates grind along a mutual boundary, and it is released through small temblors or via a major earthquake. The shift under Haiti came in a horizontal, side-to-side motion.

It was Haiti's first earthquake in a century.

But while the geological events behind the Haitian earthquake are somewhat startling, it is highly unlikely that the temblor had anything to do with the recent seismic events in California, or that it presages another pending disaster elsewhere, scientists say.

"The rate of earthquakes is more-or-less constant on a global scale," Bowman told FoxNews.com. "However, as the Earth's population continues to grow and as our societies become ever more linked through communication and commerce, our awareness of individual earthquakes has grown.

"There is no known connection between these events," he said. "The fact that these earthquakes happened so closely together in time is a coincidence. To draw an analogy, USC, my alma mater, won the 2004 BCS Championship in Football, and Cal State Fullerton, my employer, won the 2004 College World Series. Is there some connection between them? No."

Nevertheless, scientists believe a tremendous earthquake in California is almost inevitable. In 2008, a multi-disciplinary collaboration of scientists and engineers released the Uniform California Earthquake Rupture Forecast (UCERF), which predicts a 99.7 percent likelihood of a 6.7 or larger earthquake in California in the next 30 years.

Other disasters may be in store for Americans as well, notably the so-called "supervolcano" beneath Yellowstone National Park

"This is an active volcanic and tectonic area, and these are the kinds of things we have to pay attention to," said Robert Smith, who directs the Yellowstone Seismic Network, which operates seismic stations around the park. He said quakes in the park have ranged in strength from barely detectable to one of magnitude 3.8 that happened last year.  

"Could it develop into a bigger fault or something related to hydrothermal activity? We don't know. That's what we're there to do, to monitor it for public safety."

Lubos Motl, a Czech theoretical physicist, and former Harvard University assistant professor, said a particular earthquake can be predicted only "a few seconds" before it begins. "Earthquakes are really fast, and pretty much random, geological events," he said, adding: "It's somewhat unlikely that our ability to forecast earthquakes will increase significantly when the technology gets better." 

Keith Lockitch, a fellow at the Ayn Rand Institute in New York City, said Haiti, the most impoverished nation in the Western Hemisphere, suffered terribly because its economy makes it much less resilient to disasters like earthquakes and hurricanes.

"The toll of death and human suffering is much worse in a pre-industrial country like Haiti than it would be from a comparable quake near, say, San Diego," Lockitch said. "What the tragedy in Haiti should make us realize is just how important industrial development under capitalism is in keeping people as safe as possible from such events."

Others advise caution in overestimating the scientific importance of the Haiti earthquake, even though TV imagery demonstrates the great human tragedy. "In the scheme of things, neither of the earthquakes was really that big," says Susan Hough, a seismologist at the U.S. Geological Survey, Pasedena, Calif., and author of Predicting the Unpredictable: The Tumultuous Science of Earthquake Prediction. Regarding the quakes in Haiti and Northern California, she pointed out, "What's notable of the recent events is that both struck close to where people live."

 Fierce Quake Devastates Haitian Capital

Haiti’s damaged National Palace.

 

Published: January 12, 2010

SANTO DOMINGO, Dominican Republic — A fierce earthquake struck Haiti late Tuesday afternoon, causing a crowded hospital to collapse, leveling countless shantytown dwellings and bringing even more suffering to a nation that was already the hemisphere’s poorest and most disaster-prone.

The earthquake, the worst in the region in more than 200 years, left the country in a shambles. As night fell in Port-au-Prince, Haiti’s capital, fires burned near the shoreline downtown, but otherwise the city fell into darkness. The electricity was out, telephones were not working and relief workers struggled to make their way through streets blocked by rubble.

In the chaos, it was not possible for officials to determine how many people had been killed and injured, but they warned that the casualties could be substantial.

The physical toll was easier to assess. The headquarters of the United Nations mission was seriously damaged, the United Nations said in a statement, and many employees were missing. Part of the national palace had collapsed, The Associated Press reported.

A hospital collapsed in Pétionville, a hillside district in Port-au-Prince that is home to many diplomats and wealthy Haitians, a videographer for The Associated Press said. And an American government official reported seeing houses that had tumbled into a ravine.

Tequila Minsky, a photographer based in New York who was in Port-au-Prince, said that a wall at the front of the Hotel Oloffson had fallen, killing a passer-by. A number of nearby buildings had crumbled, trapping people, she said, and a Unibank bank building was badly damaged. People were screaming.

“It was general mayhem,” Ms. Minsky said.

The earthquake, with a magnitude estimated at 7.0, struck just before 5 p.m. about 10 miles southwest of Port-au-Prince, the United States Geological Survey said. Many aftershocks followed and more were expected, said David Wald, a Geological Survey seismologist.

“The main issue here will probably be shaking,” he said, “and this is an area that is particularly vulnerable in terms of construction practice, and with a high population density. There could be a high number of casualties.”

Oxfam, an antipoverty group, said that Kristie van de Wetering, a former employee based in Port-au-Prince, had described houses in rubble everywhere.

“There is a blanket of dust rising from the valley south of the capital,” agency officials said Ms. van de Wetering had told them. “We can hear people calling for help from every corner. The aftershocks are ongoing and making people very nervous.”

The earthquake could be felt across the border in the Dominican Republic, on the eastern part of the island of Hispaniola. High-rise buildings in the capital, Santo Domingo, shook and sent people streaming down stairways into the streets, fearing that the tremor could intensify.

Haiti sits on a large fault that has caused catastrophic quakes in the past, but this one was described as among the most powerful to hit the region. With many poor residents living in tin-roof shacks that sit precariously on steep ravines and with much of the construction in Port-au-Prince and elsewhere in the country of questionable quality, the expectation was that the quake caused major damage to buildings and significant loss of life.

“Everybody is just totally, totally freaked out and shaken,” Henry Bahn, an official of the United States Department of Agriculture who was visiting Haiti, told The Associated Press. “The sky is just gray with dust.”

Haiti’s many man-made woes — its dire poverty, political infighting and proclivity for insurrection — have been exacerbated repeatedly by natural disasters. At the end of 2008, four hurricanes flooded whole towns, knocked out bridges and left a destitute population in even more desperate conditions.

The United States and other countries have devoted significant humanitarian support to Haiti, financing a large United Nations peacekeeping mission that has recently reported major gains in controlling crime. International aid has also supported an array of organizations aimed at raising the country’s dismal health and education levels.

Emergency meetings were being held in Washington, and President Obama issued a statement saying that administration officials were closely monitoring the situation.

“We stand ready to assist the people of Haiti,” Mr. Obama said.

The Caribbean is not usually considered a seismic danger zone, but earthquakes have struck here in the past.

“There’s a history of large, devastating earthquakes,” said Paul Mann, a senior research scientist at the Institute for Geophysics at the University of Texas, “but they’re separated by hundreds of years.”

Most of Haiti lies on the Gonave microplate, a sliver of the earth’s crust between the much larger North American plate to the north and the Caribbean plate to the south. The earthquake on Tuesday occurred when what appears to be part of the southern fault zone broke and slid.

The fault is similar in structure to the San Andreas fault that slices through California, Dr. Mann said.

Such earthquakes, which are called strike-slip, tend to be shallow and produce violent shaking at the surface.

“They can be very devastating, especially when there are cities nearby,” Dr. Mann said.

Victor Tsai, a seismologist at the National Earthquake Information Center of the United States Geological Survey, said the depth of Tuesday’s earthquake was only about six miles and the quake was a 9 on a 1-to-10 scale that measures ground shaking. “We expect substantial damage from this event,” he said.

In the Little Haiti neighborhood of Miami, customers began streaming into the Louis Market shortly after news of the earthquake hit the airwaves. They were buying $5 phone cards in a desperate attempt to reach relatives in Haiti.

“Everyone who walks in here is crazy, worried, depressed,” said Myrlande Cherenfant, 20.

At the Notre Dame de Haiti Roman Catholic church, a handful of parishioners in red-cushioned seats pressed redial on their phones over and over. Some said that they had been able to get through immediately after the earthquake.

“I was able to talk to a priest in Haiti,” the Rev. Reginald Jean-Mary said. “The only word I heard was ‘catastrophe’ and then it cut off.”

He said that in a later call he was told that the cathedral in Port-au-Prince had been destroyed and that other churches had been damaged.

Jean-Robert Lafortune, executive director of the Miami-based Haitian American Grassroots Coalition, said that Haiti had endured “a cycle of natural disasters and man-made disasters, and this is one more big catastrophe.”

“We are in trauma,” he said. “We have loved ones there and many of them will be victims. We’re calling and calling, but there’s nothing on the other end.”

Simon Romero reported from Santo Domingo, and Marc Lacey from Mexico City. Reporting was contributed by Elisabeth Malkin from Mexico City, Damien Cave from Miami, and Kenneth Chang and Liz Robbins from New York.
