The Geotechnical Engineering Office (GEO) in Hong Kong have released via Youtube two videos reconstructing the devastating landslides of 1972 and 1976.  These events were the trigger for the formation of GEO, and the initiation of the most successful landslide management programme in history.  The first reconstructs and simulates the Po Shan Road landslide:

The second looks at the 1972 and 1976 landslides in Sau Mau Ping:

These are quite excellent resources (although for some reason the second one kept freezing for me at the four minute point – I hope this is due to my internet connection in Switzerland).
