MOSCOW (Sputnik) — Aftershocks were registered at 08:16 local time on Sunday (22:16 GMT on Saturday). The epicentre of the quake was located 76 kilometres (47 miles) to the northeast of Lae, the second largest city in Papua New Guinea, at a depth of 46 kilometres (some 29 miles), the United States Geological Survey (USGS) said.

In Papua New Guinea, which is part of the so-called Pacific Ring of Fire, earthquakes are frequent due to the intense seismic activity.
