New 7.6 quake rocks Chile, tsunami alarm bells ring - PHOTOS

03 April 2014 [11:45] - TODAY.AZ
A powerful 7.6-magnitude earthquake struck off northern Chile late on Wednesday, prompting tsunami alerts and evacuations along the coast and in neighboring Peru.

It was the strongest of several aftershocks that followed a huge 8.2-magnitude quake blamed for six deaths in the same region on Tuesday.

Chile's emergency office Onemi said there were no initial reports of casualties or serious damage from the latest quake.

President Michelle Bachelet, who had gone to the area to inspect the damage from the earlier quake, was evacuated from her hotel in the city of Arica.

The new quake was located 12 miles south of the port town of Iquique at a relatively shallow depth of 12.4 miles, the U.S. Geological Survey said.

The Pacific Tsunami Warning Center said that while there was no widespread tsunami threat, the latest tremor could generate a local tsunami.

The bigger earthquake on Tuesday triggered a tsunami with 2-meter (7-foot) waves and officials said it caused six deaths.

More than 2,600 homes were damaged and fishing boats along the northern coast were smashed up.

However, most infrastructure held up and key copper mines were generally functioning normally. Chile is the world's No. 1 copper producer.

Chile's 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.

Bachelet, who was sworn in as president less than a month ago, is conscious of the stinging criticism she faced near the end of her first term in office in 2010, when her government was seen to have responded inadequately to a massive 8.8-magnitude quake and tsunami that killed 526 people.

Chileans live in one of the most earthquake-prone areas of the world. In 1960, southern Chile was hit by a 9.5 quake, the largest in modern history.

Residents in the area of the latest quakes have been expecting "the big one" for many years. The Nazca and South American tectonic plates rub up against each other just off the coast of Iquique, where a "seismic gap" has been building up.

An unusually large number of tremors in the area in recent weeks had led authorities to reinforce emergency procedures, while residents bought rations and prepared for an eventual evacuation.

However, the mega-quake they had been fearing may still be yet to happen, said Paul Earle, a seismologist at the U.S. Geological Survey National Earthquake Information Center.

"This earthquake was not large enough to release the stress on the whole area where they believe the seismic gap is," he said. "It's going to take some time to evaluate the effect of this earthquake on that region. But people should stay prepared."
