Due to the devastation of past earthquakes, quake-proof structures are predominant in [[New Britain]] and [[New Ireland (island)|Ireland]], parts of [[Fiji]] and [[New Caledonia]] Prefectures, as well as in [[Madang Province]], where they co-exist with many weaker and older structures.
Due to the {{M|w}}9.43 2023 New Guinea earthquake and tsunami (scientifically known as the Great Papua earthquake), which caused extreme destruction in [[Wewak]], [[Madang]] and [[Mount Hagen]], destroyed buildings in the [[Momase Region]] are being rebuilt with more strict guidelines, with 80% of the region's destroyed buildings reconstructed by December 2023.
