n earthquake of magnitude 7.2 struck New Guinea, Papua New Guinea region early on Monday, according to the European Mediterranean Seismological Centre (EMSC).
The quake was at a depth of 80 km (49.71 miles), it added.
The US Tsunami Warning System said there was no tsunami warning after the quake.
Loosening of soft ground in the quake zone has potential to cause damage to communities in the area, the USGS said, although the area is sparsely populated.
Such loosening, known as liquefaction, can cause substantial subsidence and horizontal sliding of the ground and result in major damage, the seismology agency said.
The earthquake shook an area about 100 kilometers east of the border with Indonesia on the island of New Guinea.
The remote New Britain region, part of an archipelago in eastern Papua New Guinea, was struck by a magnitude 6.2 earthquake in late February.
