Filed under Landslides

The day after the earthquake struck in Kaikoura, post-earthquake damage assessment teams were onsite to assess the damage caused by the shaking. The abundance of earthquake-induced landslides was particularly noticeable. Hereafter is a collection of photographs of some of the landslides seen. Waipapa...
