The Pacific Tsunami Warning Center initially issued a tsunami warning but said about an hour later the danger had passed.

Papua New Guinea experienced the highest levels of earthquakes and volcanic eruptions, with 64 earthquakes of magnitude 6.0 or greater - eight of which were 7.0 or greater - struck within 250 km of events on Friday in the past 50 years. The island nation is located along the "Ring of Fire", the main area in the Pacific Ocean valley where most of the world's seismic activity occurs

Papua is an earthquake prone country. many earthy plates often move.

quake of magnitude 7,5...

Foreign experts sometimes refer to the active earthquake source zone as Mamberamo Deformation Zone (MDZ) or Mamberamo Thrust and Fold Belt (MTFB). "Because of this active tectonic condition, it is only natural that the Sarmi and Jayapura areas become earthquake-prone areas and have the most active seismic activity in Papua," he said.

Based on the epicenter location, depth, and earthquake source mechanism in the form of a combination of faults with upward and horizontal movements (oblique thrust), the earthquake that occurred is a type of shallow crustal earthquake which is strongly suspected due to the Fault Factoring Mamberamo (Mamberamo thrust)
