Amid frantic rescue efforts and isolated outbreaks of looting, the Chilean president on Sunday raised the earthquake death toll to 708 and sent soldiers into the shattered streets to both keep order and speed the distribution of aid.
President Michelle Bachelet called the damage caused by Saturday's magnitude-8.8 quake "an emergency unparalleled in the history of Chile" and suggested the death toll would likely spiral higher in the days ahead.
Some 2 million were said to be displaced, injured or otherwise impaired by the disaster. Untold numbers remained missing.
In devastated Concepcion, police fired water cannons and tear gas to disperse hundreds of people who forced their way into shuttered shops and were making off with food, water and diapers but also television sets. Several banks, pharmacies and gasoline stations were also hit.
Authorities, heeding the cries of residents that they lacked food and water, reached a deal with supermarket chains to give away food to needy residents.
"We are overwhelmed," a police officer said.
Using power saws and their bare hands, rescue workers tried to recover those caught inside, but efforts to determine the full scope of destruction were undermined by an endless string of terrifying aftershocks that continued to turn buildings into rubble.
The massive earthquake, one of the strongest in recorded history, left a devastating imprint on a country that knows quakes well.
