WELLINGTON, New Zealand — Further landslides are likely to plague the area where part of a mountain collapsed onto a remote village in Papua New Guinea two weeks ago, New Zealand geological experts warned Friday, as authorities ended search and rescue efforts.
It remains unclear how many people died in the massive landslide in Papua New Guinea’s Enga region on May 24, with the national government reporting more than 2,000 people have been buried alive and a U.N. estimate putting the death toll at around 670.
Only 11 bodies have been recovered so far.
New Zealand geotechnical engineers sent to Papua New Guinea released a report on Thursday raising concerns about the stability of the ground not just in the landslide but also to either side of it.
“We believe that there is real potential for further landslides to occur in the near or medium term,” Aaron Waterreus, the leader of the Fire and Emergency New Zealand (FENZ) team that includes the geotechnical engineers, said in a news conference on Friday.
FENZ geotechnical engineer Jan Kupec added that the landslide, which covers about 35 acres, is of such a scale that it is impossible to stop it from moving and it could continue to move for months or even years.
He said the rock avalanche was most likely part of an old landslide that has been reactivated and that there were now concerns that the start of monsoon rains will liquify the material that fell off the hill and reactivate it again.
The Enga provincial government on Thursday announced mass evacuations of further areas around the landslide due to concerns that there could be more earth movement.
The government has ceased searching for bodies and the area has been deemed a mass burial site.
The U.N. International Organization for Migration said more than 7,200 people were displaced by the landslide and that the numbers might increase.
Treacherous terrain and tribal unrest in the area mean heavy equipment and aid have been slow to arrive, and Papua New Guinea government officials a week ago ruled out finding survivors under the rubble.
The disaster site will be quarantined with access restricted to prevent the spread of disease from decaying bodies, according to the IOM.
