A moderate earthquake has struck near the South Pacific nation of Vanuatu, but no tsunami warning has been issued and there are no immediate reports of injury or damage. The US Geological Survey says the magnitude 5.9 quake struck on Tuesday 43 miles (69 kilometers) east of the city of Isangel, at a depth of 22 miles (35 kilometers).
No tsunami warning has been issued by the Pacific Tsunami Warning Center.
Vanuatu is part of the Pacific "ring of fire" _ an arc of earthquake and volcanic zones stretching from Chile in South America through Alaska and down through Vanuatu to Tonga in the South Pacific.
The nation consists of a chain of 83 islands and it lies just over 1,400 miles (2,200 kilometers) northeast of Sydney, Australia.
