Proactive disclosure Print version   | |  Landslides Khyex River Landslide, British Columbia
The Khyex River Landslide occurred on Friday November 28, 2003 between 00:20-00:30 PST. This is when Pacific Northern Gas Ltd noticed a pressure loss in the pipeline. Approximately 300 m of 8-inch pipeline was lost. As a result, most of Prince Rupert residents were without natural gas or heat for 10 days. A few days after the landslide occurred, a temporary 2-inch gas line was installed to restore partial service. This is a spectacular landslide because it not only flowed downstream, but crossed the river and flowed upstream for 100's of metres (see photos). This type of landslide took place very rapidly and in very sensitive glaciomarine muds; it is called a retrogressive earthflow. Preliminary field investigations were carried out by Jim Schwab, Marten Geertsema from the BC Ministry of Forests, and Andrée Blais-Stevens from the Geological Survey of Canada. The estimated volume of material displaced by the landslide is up to 4.7 million cubic metres. It is thought that the slope failure was triggered by erosion of the riverbank. However, more investigations will be needed to determine the exact cause of the landslide and factors that led to the failure.
