The Saidmarreh Landslide
March 29, 2014 | Geology.com
The Saidmarreh Landslide in western Iran is one of the largest landslides in the world. It occurred about 10,000 years ago when about 5 cubic miles of limestone detached along bedding planes and slipped down the north flank of the Kabir Kuh anticline. The slide debris had a run-out distance of over 9 miles. It can be clearly seen on satellite images today.

Landslide Mapping Needed in North Carolina
November 26, 2013 | WSPA.com
Hundreds of landslides occur every year in North Carolina but lawmakers have almost eliminated a program that can help developers avoid building homes, commercial and public buildings on ancient landslides and slide-prone areas. It can also help the state highway department and utility companies avoid building roads and pipelines across ancient landslides and slide-prone areas. This one-time job was costing about $350,000 per year and would only require mapping the western part of the state where most landslides occur.
In a 24-year period landslides in the state killed 7 people and destroyed 85 homes. Not available
