Papua New Guinea is one of the world’s most active seismic areas. On the surface, huge landslides are found on mountainsides and steep canyons slopes. Underground large passages and megadolines result mainly from the erosion of soft limestones by underground streams, but seismic movements may accelerate their evolution. Morphological characteristics were derived from statistical data and field observations.
