While the search is still on for villagers buried by the massive landslide in the southern highlands of PNG questions are now being asked about its causes.
The disaster struck near the Tumbi quarry of the giant ExxonMobil liquefied natural gas project near Hides last week.
According to initial reports, the whole side of a mountain collapsed, covering an area stretching about 2km and 500m wide.
Tim Sullivan, an adjunct professor at the University of New South Wales specialises in landslides and he supplied the independent geotechnical report for the coroner following the 1997 landslide at the alpine resort at Thredbo in NSW.
