Three strong earthquakes strike Chile in quick succession

Story: Three strong earthquakes rocked Chile this morning, just as the country was swearing in a new president. A 7.2-magnitude earthquake hit at 11:39 a.m. local time (9:39 a.m. ET), followed by a 6.9-magnitude quake 16 minutes later, the U.S. Geological Survey reported. A third, measured at magnitude 6.0, came 27 minutes later. They were the strongest aftershocks to rattle Chile since a February 27 earthquake on the country's west coast that toppled buildings and spawned a tsunami, killing several hundred people.
