A 6.3-magnitude earthquake struck Tuesday in the Bismarck Sea about 200 kilometers (120 miles) off Papua New Guinea's coast, the US Geological Survey said.
A preliminary USGS assessment said there was a "low likelihood of casualties and damage from the quake", which had an estimated depth of 10 kilometers. There were no tsunami warnings.
Papua New Guinea sits on the so-called Pacific Ring of Fire, which is a hotspot for seismic activity due to friction between tectonic plates.
A 7.5-magnitude quake that hit the rugged highlands region in February 2018 triggered landslides, burying homes and killing at least 125 people. —Agence France-Presse
