In the town of Constitucion alone, about 350 people died, state TV quoted emergency officials as saying.

Looting also broke out in parts of the capital, Santiago.
"We don't have water or anything. No one has appeared with help and we need more police to keep order. There are many people here who are robbing," said a 78-year-old woman who identified herself as Ana in the badly hit city of Talca, 250km south of Santiago.
In Concepcion, angry survivors camping along roads took out their frustration on firefighters who were distributing drinking water in thermoses and tea kettles, damaging their vehicles.
Copper prices surged in early trading today due to supply worries, jumping 5.6pc to $7,600 per tonne on the London Metal Exchange.
