We pay our respect to them and their cultures and to the elders past and present. Landslide: A landslide or landslip is a geological phenomenon which includes a wide range of ground movements, such as rockfalls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. The most devastating landslide in history happened in 1920 in Gansu, China. Compounding the hazards, these natural disasters often occur along with other similar natural phenomena, such as floods or earthquakes. They measure the severity by how far the landslide debris extends into model houses placed in the flood plain. True Tales Gansu Landslide. Use the Landslide Images PowerPoint presentation as a helpful classroom tool. The amplitude of ground shaking is affected by the type of near-surface rocks and soil.

To minimize risk, the slope of land and materials underground must be This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment.

This timeline activity will help students to understand how and why the deadly landslides occurred. Show the PowerPoint presentation, or print out the slides to use with an overhead projector. You may wish to use this resource to open discussion about international aid, climate change or planning for natural disasters.

This landslide killed over 180,000 people and left many more homeless.

Landslides not only are dangerous — causing on average more than 25 deaths and over $1 billion in damages a year — but are also widespread, occurring in all 50 states. Classroom Resources. Mini-Landslide - Activity Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. Teaching resources for primary and secondary levels including background information, student activities, full-colour cut-out 3D models and posters.
