One of the largest earthquakes ever recorded tore apart houses, bridges and highways in central Chile and sent a tsunami racing halfway around the world.
Chileans near the epicentre were tossed about as if shaken by a giant, and the head of the emergency agency said authorities believed at least 300 people were dead.
The magnitude-8.8 quake was felt as far away as Sao Paulo in Brazil – 1,800 miles to the east.
The full extent of damage remained unclear as dozens of aftershocks – one nearly as powerful as Haiti’s devastating January 12 earthquake – shuddered across the disaster-prone Andean nation.
President Michelle Bachelet declared a “state of catastrophe” in central Chile but said the government had not asked for assistance from other countries.
If it does, President Barack Obama said, the United States “will be there.” Around the world, leaders echoed his sentiment.
In Chile, newly built apartment buildings slumped and fell. Flames devoured a prison. Millions of people fled into streets darkened by the failure of power lines. The collapse of bridges tossed and crushed cars and trucks, and complicated efforts to reach quake-damaged areas by road.
At least 214 people were killed and 15 were missing as of Saturday evening, Ms Bachelet said in a national address on television.
While that remained the official estimate, Carmen Fernandez, head of the National Emergency Agency, said later: “We think the real figure tops 300. And we believe this will continue to grow.”
Ms Bachelet also said 1.5 million people had been affected by the quake, and officials in her administration said 500,000 homes were severely damaged.
In Talca, just 65 miles from the epicentre, people sleeping in bed suddenly felt like they were flying through major airplane turbulence as their belongings cascaded around them from the shuddering walls at 3.34am (0634 Irish Time).
Also near the epicentre was Concepcion, one of the country’s largest cities, where a 15-story building collapsed, leaving a few floors intact.
“I was on the eighth floor and all of a sudden I was down here,” said Fernando Abarzua, marvelling that he escaped with no major injuries. He said a relative was still trapped in the rubble six hours after the quake, “but he keeps shouting, saying he’s OK”.
Chilean state television reported that 209 inmates escaped from prison in the city of Chillan, near the epicentre, after a fire broke out.
In the capital of Santiago, 200 miles to the northeast, the national Fine Arts Museum was badly damaged and an apartment building’s two-story parking lot collapsed, smashing about 50 cars whose alarms rang incessantly.
A car dangled from a collapsed overpass while overturned vehicles lay scattered below. “I can now say in all surety that seat belts save lives in automobiles,” said Cristian Alcaino, who survived the fall in his car.
While most modern buildings survived, a bell tower collapsed on the Nuestra Senora de la Providencia church and several hospitals were evacuated due to damage.
Santiago’s airport was closed, with smashed windows, partially collapsed ceilings and destroyed pedestrian walkways in the passenger terminals. The capital’s subway was shut as well, and transportation was further limited because hundreds of buses were stuck behind a damaged bridge.
Chile’s main seaport, in Valparaiso about 75 miles from Santiago, was ordered closed while damage was assessed. Two oil refineries shut down, and lines of cars snaked out of service stations across the country as nervous drivers rushed to fill up.
The state-run Codelco, the world’s largest copper producer, halted work at two of its mines, although it said it expected them to resume operations quickly, the newspaper La Tercera reported.
President-elect Sebastian Pinera angrily reported seeing some looting while flying over damaged areas. He vowed “to fight with maximum energy looting attempts that I saw with my own eyes”.
The jolt set off a tsunami that swamped San Juan Bautista village on Robinson Crusoe Island off Chile, killing at least five people and leaving 11 missing, said Guillermo de la Masa, head of the government emergency bureau for the Valparaiso region. He said the huge waves also damaged several government buildings on the island.
Pedro Forteza, a pilot who frequently flies to the island, said: “The village was destroyed by the waves, including the historic cemetery. I would say that 20 or 30% has disappeared.”
On the mainland, several huge waves inundated part of the major port city of Talcahuano, near the hard-hit city of Concepcion. A large boat was swept more than a block inland. Mr Pinera flew over the area and said an unspecified number of people had died in Talcahuano.
Waves also flooded hundreds of houses in the town of Vichato, in the BioBio region.
The surge of water raced across the Pacific, setting off alarm sirens in Hawaii, Polynesia and Tonga and prompting warnings across all 53 nations ringing the vast ocean.
Tsunami waves washed across Hawaii, where little damage was reported. The US Navy moved a half-dozen vessels out of Pearl Harbour as a precaution, Navy spokesman Lieutenant Myers Vasquez said.
Shore-side Hilo International Airport was closed. In California, officials said a three-foot surge in Ventura Harbor pulled loose several navigational buoys.
The first tsunami waves hit Japan’s outlying islands early today, but while the initial waves were small and most of the Pacific islands already in its path had been spared damage, officials warned a bigger surge could follow.
Japan’s Meteorological Agency said the first waves were recorded in the Ogasawara islands. It was just four inches high. Another, measuring about 12 inches, was observed in Hokkaido, to the north. There were no reports of damage.
