LIMA (Reuters) - A major quake of magnitude 7.5 struck the Peruvian-Brazilian border in the Amazon basin on Tuesday (Nov 24), the United States Geological Survey (USGS) said, but there were no immediate reports of damage.
The quake, initially reported as a magnitude 7.1, was felt all the way to the south of Peru, close to the Chilean border, according to local media. The quake could also be felt in the capital, Lima, 681km away to the east, witnesses said.
Peru's Geophysics Institute reported an initial quake of magnitude 7.3, followed by one of magnitude 7.2. The main quake's epicentre was located 296km north-west of the Peruvian city of Puerto Maldonado.
It was very deep, 602km below ground, and in a sparsely populated jungle area of the Amazon so was unlikely to cause much damage or casualties.
The USGS said a second quake, of magnitude 5.9 struck nearby a few minutes later, also very deep.
The head of Peru's emergency services Alfredo Murgueytio said the quake and an aftershock hit the Amazon region. "At this point there are no reported damages," he said.
A representative of mining company Southern Copper , one of Peru's biggest copper producers located in Southern Peru, said operations were undamaged. Peru is the world's No. 3 copper producer.
Several residents of the Brazilian city of Brasileia, 247km west of the epicentre, told Reuters they felt the ground shake and that chairs and tables rattled during the quake, but that there was no visible damage.
