Chile's Supreme Court suspended a key permit for Canadian miner Goldcorp Inc's El Morro copper-gold project, the latest setback for the controversial project and one of the biggest legal blows to a mining project in the world's top copper producer.

El Morro, Goldcorp's only major asset in Chile, had its environmental permit for the $3.9 billion project struck down in February by an appeals court at the request of an indigenous agricultural community. Chile's Supreme Court upheld the ruling on Friday.

Peru became the latest developing country to enact a domestic climate change initiative in the absence of a binding global pact, adopting a resolution on Thursday to lower carbon emissions in its fast-growing economy.

As one of the world's most geographically diverse places, Peru said it is already feeling the effects of a changing climate, such as melting tropical glaciers in the Andes and high levels of solar radiation.

A powerful 6.7 magnitude earthquake struck near Chile's eastern port of Valparaiso early on Tuesday, shaking buildings as far away as the capital Santiago, but there were no reports of significant damage and the country's main copper mines were unaffected.

One elderly man died as a result of a heart attack brought on by the quake, which struck 26 miles (42 km) north-northeast of Valparaiso, and 69 miles (112 km) northwest of the capital Santiago, but there were no other reports of injuries.

A strong magnitude-6.5 earthquake shook central Chile, prompting authorities to order a preventative evacuation of a stretch of coastline.

There were no immediate reports of damage or deaths, but the quake was felt almost a minute in Valparaiso and the capital, Santiago, where hundreds of people fled buildings and homes in panic.

A strong 6.5-magnitude earthquake struck off the coast of central Chile late Monday but does not appear to have generated a major tsunami, according to US monitors.

The quake sent tremors through the Chilean capital Santiago, sparking concern and causing power outages, but there were no immediate reports of casualties or damage, according to witnesses and local authorities.

A magnitude 7.2 earthquake hit central Chile on Sunday, shaking buildings in the capital of Santiago, but there were no immediate reports of serious damage or injuries.

The government emergency agency, ONEMI, said it was preventively evacuating some areas of the coast, but quickly revoked that decision.

The U.S. Geological Survey said the quake struck 64 miles west north west of the town of Talca at a depth of 6.2 miles.

Ireland's Mainstream Renewable Power and Chinese wind turbine maker Xinjiang Goldwind Science & Technology Co. have formed a 50-50 joint venture to build a 70 megawatt wind farm in Chile, the firms said on Monday.

Construction of the first 70 MW phase of the Ckani wind farm in northern Chile should start by the end of this year, and it has the potential to have a capacity of 240 MW capacity on stream by 2015, the companies said in a statement.

The value of the whole project is $480 million, while the first phase is worth $140 million.

People exposed to very high levels of arsenic in Chilean drinking water back in the 1950s and 60s are still showing a higher-than-normal risk of bladder cancer -- years after the arsenic problem was brought under control, a new study shows. The findings are not surprising, researchers say, since the cancer would take decades to emerge. But the results underscore the importance of continuing to screen high-risk people for bladder cancer, according to lead researcher Dr. Fernando Coz, a professor of urology at the Universidad de Los Andes in Santiago de Chile.
