WELLINGTON: An earthquake of magnitude 6.0 struck off the South Pacific island nation of Samoa on Thursday, seismologists reported, two weeks after a violent quake caused a tsunami that devastated Tonga, Samoa and American Samoa.
No immediate tsunami alert was issued by the Pacific Tsunami Warning Center in Hawaii following the quake, which struck at 6:00 am (1800 GMT Wednesday) at a narrow depth of 10 kilometres (six miles).
The epicentre was 365 kilometres southwest the Samoan capital of Apia, the US Geological Survey said.
