Five earthquakes, including a 7-magnitude quake, rattled the Falkland Islands for more than 2 hours Monday, the U.S. Geological Survey said. The other four quakes all registered greater than magnitude-5, the USGS said. There were no immediate reports of injuries or damage. The strongest earthquake, at a depth of 6.2 miles, was about 195 miles southeast of Stanley in the Falklands and 545 miles east of Ushauaia, Argentina.
