SANTIAGO - Chilean authorities on Wednesday were assessing the damage from a massive earthquake that struck off the northern coast, causing a small tsunami, but the impact appeared to be mostly limited.

The 8.2 magnitude quake that shook northern Chile on Tuesday killed six people and triggered a tsunami with 2-meter (7-foot) waves.

As the ocean waves receded, over 900,000 people who had evacuated the country's low-lying coastal areas returned to their homes, some to find their houses and livelihoods in ruins.

More than 2,600 homes were damaged and fishing boats along the northern coast were smashed up. However, most infrastructure held up and mines in the world's No. 1 copper producer were generally functioning normally.

The arid, mineral-rich north is sparsely populated, with most of the population concentrated in the port towns of Iquique and Arica, near the Peruvian border.

In Peru, the earthquake led to temporary power outages and evacuations in some southern towns, but did not cause serious damage or injuries.

Chilean President Michelle Bachelet visited Iquique on Wednesday and praised people's orderly response to the emergency.

"We are here to recognize the calm behavior of the people of Iquique who showed great civic responsibility, as did those of Arica. I think you have given us all a tremendous example," she said.

The government would put great effort into restoring services, she added.

Finance Minister Alberto Arenas said the government would place "no limit on the use of resources to address this emergency."

Bachelet, who was sworn in as president less than a month ago, is likely conscious of the stinging criticism she faced near the end of her first term in office in 2010, when the government was seen to have responded inadequately to a much bigger 8.8 quake and tsunami that killed over 500 people.
