A Papua New Guinea NGO which provides scrutiny of the country's major gas project, led by Exxon Mobil, says an investigation into the Tumbi landslide which the government promised still hasn't started.
The disaster in the Southern Highlands on January 24th is believed to have killed at least 25 people.
Locals have blamed the landslide on the Tumbi quarry, which was used by Exxon for its project and sits atop the massive landslide.
Stanley Mamu of LNG Watch says the official response has so far focussed on clearing the main road which was cut off in the landslide.
He says the local community wants an independent probe but, after waiting over a month, has started its own investigations.
"The investigation team organised by the landowners are on the ground and compiling their report currently. The government said it would send an investigation team but I haven't heard that it's in place so I don't know when they'll be sending the investigation team down."
