The 8.8 magnitude quake - one of the most powerful recorded - devastated² central parts of the country, killing³ more than 700 people.

Troops are being deployed⁴ to help with rescue efforts and prevent looting（抢劫，洗劫） .

A curfew（宵禁） is in force in some areas. Basic supplies are to be distributed as rescuers reach worst-hit areas.

"We face a catastrophe⁵ of such unthinkable magnitude that it will require a giant effort," Ms Bachelet told reporters on Sunday in the capital, Santiago.

The curfew, which began at 2100 local time (midnight GMT), applies in the region of Maule - where more than 541 are confirmed dead - and in Concepcion, Chile's second city.

Both areas are being placed under special rules to speed up the delivery of aid.

The army has been sent to support police to prevent unrest（不安，动荡） in Concepcion, south of Santiago.

The mayor has said food is running out and the situation in the city is getting out of control. Supermarkets and chemists have been looted and thousands of people remain homeless.

Meanwhile rescue teams are still trying to reach dozens of people believed to be trapped in a collapsed⁶ block of flats in Concepcion.

Many Chileans are spending a second night outdoors, afraid to stay in damaged homes.

Reports say 350 bodies were found in the devastated（毁坏的） fishing village of Constitucion - which was hit by both the quake and the tsunami it set off.

In the port of Talcahuano more than 20 boats were swept ashore⁷ and dumped in the streets by the waves.

The emergency measures announced by Ms Bachelet also include:
Air force flights to deliver supplies to affected⁸ areas
Free distribution of basic goods in Maule and Biobio regions - distribution points are yet to be decided⁹
Efforts to guarantee electricity distribution, as many areas remain without power

Officials say public transport services are slowly returning to normal. One metro¹⁰ line in Santiago is operating. Roads are passable, although with diversions.

The airport in Santiago has reopened. It had been closed because of damage to the terminal and control tower.
