Aftershocks In South Pacific

NUKU’ALOFA, Tonga - A pair of aftershocks rattled the South Pacific island nation of Tonga on Friday but caused no damage or injuries, a day after a large quake exposed alarming cracks in a tsunami warning system. A magnitude 6.0 and a magnitude 5.4 aftershock hit the same region of Tonga, the U.S. Geological Survey reported, but there was no sign of any damage in the capital and no tsunami warnings were issued. The Hawaii-based Pacific Tsunami Warning Center said Tonga and four other Pacific nations were inadvertantly left off a list of areas most at risk of being hit by a tsunami following the 7.8-magnitude earthquake Thursday.
