A 6.2 magnitude earthquake has struck off the Samoa islands, Geoscience Australia and the US Geological Survey (USGS) reported, adding that the epicenter of the quake is about 200 km from Apia, the capital and largest city of the island country. Apia has about 37,000 residents.
The earthquake depth is 29.8 km, USGS said. The European-Mediterranean Seismological Centre (EMSC) put the depth of the earthquake at 2km.
There have not been any reports of injuries or damage, and no tsunami warning has been issued.
The part of South Pacific Ocean where Tonga and Samoa are located is considered to be one of the most seismically active areas of the world due to high rates of convergence between the Australia and Pacific plates, the USGS said.
