A BBC correspondent says police are posted on street corners throughout the city, but that aid had yet to reach those in need in the devastated city.
12:30 PM ET -- Chile wasn't prepared for the tsunami. TIME takes a look at why the country, despite being so well prepared for the impact of an earthquake, was less effective in dealing with the tsunami that followed:
Disaster officials now say the majority of Chile's fatalities may have resulted from the temblor-generated tsunami waves that slammed coastal towns like Constitución, where 350 people were killed. And that points up the only area in which Chile and its government may have fallen short in this disaster.

Clinton flew into the capital of Santiago, delivering much-needed satellite communication equipment and a technician. It's a first installment of what she says will be substantial U.S. relief assistance.
State Department spokesman P.J. Crowley said in Washington on Monday that Chile has also asked for a field hospital and water purification systems. Other details of U.S. aid are to be worked out during Clinton's visit.

5:30 PM ET -- Looting continues. Chilean police arrested dozens of people Monday for violating a curfew which was issued in an effort to contain looting, the AP reports. (The BBC says troops arrested closer to 160 people and also shot and killed one man.) However, as a Wall Street Journal dispatch explains, packs of looters are still causing problems in the devastated city of Concepcion. "Men, women, teenagers -- even the elderly -- joined in an effort to stop gangs from invading their neighborhoods. They wore armbands to identify themselves as watch groups, and were armed with axes, sticks, stones, wooden bedposts - and sometimes guns," the Journal writes.
A curfew has been put in place from 9 p.m this evening until 6 a.m. Tuesday. More on the looting from the Los Angeles Times.

Byrs told The Associated Press that the global body was now "ready to take action."
10:40 AM ET -- Chile sends troops to quash looting. MSNBC says the country has dispatched as many as 10,000 troops to crack down on post-earthquake looting.
From the AP:
Police chief Eliecer Soler said officers arrested 55 people for violating a curfew imposed after looters sacked nearly market in town. Troops ordered into the city by Bachelet began to patrol to enforce security.
At least a few looters re-emerged to rob a market on Monday despite Bachelet's order placing the city's security under military command.
On Sunday, ingenious looters used long tubes of bamboo and plastic to siphon gasoline from underground tanks at a closed gasoline station.
Eduardo Aundez, a Spanish professor, watched with disgust as a soldier patiently waited for looters to rummage through a downtown store, then lobbed two tear gas canisters into the rubble to get them out.
"I feel abandoned" by authorities, he said. "We believe the government didn't take the necessary measures in time, and now supplies of food and water are going to be much more complicated."
