Powerful quakes strike off Fiji, Tonga
A powerful 6.8-magnitude earthquake struck off Fiji shortly after another hit off Tonga but there was no threat of a tsunami, US seismologists said. The offshore quake occurred at 9:28am on September 24, centred around 100 kilometres (62 miles) northeast of the Fijian island of Ndoi at a depth of 594km, the US Geological Survey (USGS) said on its website. It came 20 minutes after a 6.3-magnitude quake hit 124 kilometres northwest of Tonga. The Hawaiibased Pacific Tsunami Warning Center said neither quake posed a tsunami threat.
