Devastation continues to slam Indonesia after back-to-back natural disasters killed nearly 2,000 people — a number that’s expected to continue rising — with thousands more missing.

Satellite images show the coastal city of Palu being hit with a “land tsunami” or soil liquefaction — a post-earthquake effect that can occur in areas not built on firm bedrock. The shaking from an earthquake weakens and loosens the soil, resulting in massive landslides.

The images were shared on Twitter by Sutpop Purwo Nugroho, the spokesperson for Indonesia’s National Disaster Mitigation Agency, who said search and rescue teams are still working to recover bodies in the area.

The disaster followed the 7.4-magnitude earthquake and tsunami that rocked the country’s Sulawesi Island on Sept. 28.

Survivors in the nearby village of Petobo described the scene as hundreds of homes being “swallowed by the ground,” according to Forbes. Videos from the ground reveal panicked locals trying to escape the fast-moving wave and subsequent collapse of surrounding buildings.

The “land tsunami” dragged homes nearly 2,000 feet, according to the Jakarta Post.
