A powerful but deep 7.2-magnitude earthquake rocked Papua New Guinea on Tuesday, officials said, cutting power and knocking items off shelves though there were no immediate reports of serious damage.

The quake struck at a depth of 127 kilometers (80 miles) about 30 kilometers (20 miles) from the town of Bulolo at 2119 GMT Monday according to the US Geological Survey, and was felt in the capital Port Moresby about 250 kilometres away.
