New Zealands Mass wasting hazards

New Zealand has had a few notable landslides.  In 1979 a portion of the suburb of abbotsford was part of a landslide. When it was all said and done 69 people were left without homes. This layered rock landslide gave out some warning signs when a decade prior to the event residents started noticing cracks in concrete in the area. The biggest landslide documented was Green Lake, which is estimated to have occurred over 13,000 years ago. Approximately 27 cubic kilometers of material covered an area of over 45 square kilometers. Depressions left as a result of this event filled with water, to form what is no green lake.
