The earthquake, which struck at 3:49 a.m. local time, was centered about 41 kilometers southeast of Levuka on Fiji's Ovalau island and at a depth of 669 kilometers.
At the same time, the Pacific Tsunami Warning Center said that no destructive tsunami was expected in the region.
"Based on all available data, there is no tsunami threat because the earthquake is located too deep inside the Earth," the Pacific Tsunami Warning Center said.
