The epicenter was located 180.7 km (112.3 miles) SW of Lorengau (population 5 806) and 215.4 km (133.8 miles) NNE of Madang (population 27 419), P.N.G.

358 000 people are estimated to have felt light shaking.

The USGS issued a Green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.

Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake-resistant construction. The predominant vulnerable building types are informal (metal, timber, GI, etc.) and unreinforced brick masonry construction.

Recent earthquakes in this area have caused secondary hazards such as landslides and liquefaction that might have contributed to losses.
