What causes landslides? Can we predict them to save lives?

A devastating landslide struck several remote villages in the mountainous Enga province in Papua New Guinea late last week.

While it is too early for official confirmation, estimates place the death toll between 690 and 2,000 people, with thousands more missing. That only a few bodies have been recovered serves as a tragic reminder of the destructive power of these events.

The ongoing search and rescue operations have proven challenging. As often with landslides, secondary slides and rock falls are hampering efforts in the search zone. There’s also a lack of access to heavy digging machinery, and roads need to be cleared or repaired for assistance and equipment to arrive.
