By Sebastian Boyd and Michael Smith Feb. 27 (Bloomberg) — A massive 8.8 magnitude earthquake struck Chile early this morning, destroying highways, bridges and apartment buildings and leaving at least 122 people dead. Tsunami warnings were issued across the Pacific Ocean as far as Hawaii and New Zealand, and Chilean President Michelle Bachelet declared a “state of catastrophe.” The pre-dawn quake was centered 200 miles (317 kilometers) southwest of the capital Santiago near the main winemaking region and close to Concepcion, a metropolitan region of over 500,000 people. In the minutes and hours after the 90-second temblor, stronger than the one in Haiti last month that may have killed 300,000, the U.S. Geological Service reported almost 30 aftershocks. Five measured 6.0 or above. “Amid such a major earthquake we can’t rule out that the death toll will rise,” Bachelet said at a televised news conference. “We will provide information as soon as we have it.” President-elect Sebastian Pinera told reporters that at least 122 people were killed. “This earthquake is a massive blow to Chilean society,” Pinera told reporters in Santiago. Buildings collapsed across Concepcion, CHV Television reported. One four-story apartment building had fallen into a trench opened up by the quake, while another residential building was split in two, television images showed. Many streets were blocked with rubble from collapsed buildings. In towns closer to the epicenter, including Curico and Talca, more than 80 percent of buildings were flattened, CHV Television reported, citing unidentified officials at the national emergency agency. Collapsed Bridges, Roads Closer to the capital, a helicopter tour of the region showed collapsed bridges blocking motorways. Embankments fell apart, and lengthy stretches of road were impassable. Long lines of cars were visible at gasoline stations. Tsunami warnings were issued across the Pacific region, including South America, Australia, New Zealand, Japan, the Philippines, Russia and many islands, including Hawaii where the Pacific Tsunami Warning Centre said “urgent action should be taken to protect lives and property.” An evacuation of Easter Island has been ordered due to the tsunami threat, Bachelet said. Residents on the Pacific Ocean island, 2,180 miles (3,510 kilometers) west of the South American mainland, were told by the Chilean navy that the threat of a tsunami had eased. The temblor struck at 3:34 a.m. offshore from the province of Maule at a depth of 22 miles (35 kilometers), according to the U.S. Geological Survey Web site . Power and phone connections were disrupted and Santiago residents waited in the street amid fears of aftershocks, pictures on CNN+ showed. Copper Mines While the world’s largest underground copper mine, El Teniente, is 180 miles from the epicenter, most of the country’s copper deposits and port facilities are at least 500 miles to the north. Breakwater Resources Ltd., a Canadian mining company, said its Toqui mine facility was undamaged by the earthquake. “I’m trying to get in touch with Santiago,” said Gonzalo Cuadra , a London-based executive at Codelco, the world’s biggest copper producer and the owner of El Teniente. “I think in the north there haven’t been problems. We have to see what happened with the mines near Santiago.” The El Teniente underground copper mine, which is in central Chile, wasn’t damaged, Carmen Fernandez, head of the national emergency office, said in an interview in Santiago. Rio Tinto Group, a shareholder in the world’s largest copper mine, Escondida, located in northern Chile and owned by BHP Billiton Ltd., also had no reports of damage, London-based spokeswoman said Christina Mills said by telephone. State of Emergency A state of emergency was declared in Maule and the province of BioBio to the south, where Concepcion is located. A third region, Araucania, south of BioBio and the center of the country’s forestry industry, may also be added, Bachelet said. Some of the worst damage was around the cities of Talca, Curico and Cauquenes, near the quake’s epicenter, according to ONEMI, the national emergency agency. In downtown Santiago, rescue workers pulled a 92-year-old woman out of a home that had been reduced to a pile of rubble, TVN reported. The city’s international airport will be closed for at least 24 hours because of damage, airport chief Eduardo del Canto told the broadcaster. “The terminal is completely inoperable,” he said. “This is a major, damaging earthquake,” Randy Baldwin of the USGS told the BBC in an interview. “For any population in the area it would be reasonable to expect some damage.” Secretary of State Hillary Clinton is scheduled to arrive March 1 to Santiago on a regional tour. The State Department said in a statement the U.S. government is committed to helping the government of Chile “as rapidly and effectively as we can.” UN, U.K. Help While Chile “has considerable assets of its own,” the U.S. has put together a disaster response team and has placed two urban search and rescue teams on alert, State Department spokesman Philip Crowley said in a statement. “We continue to assess the situation and are prepared to offer whatever assistance Chile needs,” Crowley said. United Nations Secretary-General Ban Ki-Moon said his organization in monitoring the situation in Chile. The UN is on standby to provide emergency relief, the organization said today in an e-mailed statement. U.K. Prime Minister Gordon Brown also offered help. Chile was struck by the most powerful earthquake on record in 1960, when a magnitude 9.5 temblor killed about 1,655 people, according to the USGS Web site. A further 211 people died when associated tsunamis struck Hawaii, Japan and the Philippines. Earlier today, a magnitude 7 earthquake hit near Okinawa, Japan, at about 5:31 a.m. local time, the USGS said. Last month, Haiti was struck by a magnitude 7 quake. The death toll may reach 300,000, President Rene Preval said Feb. 21. More than 1 million people were left homeless.
