One of Canada’s largest modern landslides occurred on April 29, 1903, on Turtle Mountain in the Crowsnest Pass, located in southwestern Alberta. Approximately 30 million cubic meters of rock buried a part of the town of Frank, resulting in the death of more than 70 people. This catastrophic event is known as the Frank Slide. Since then, various governmental groups, universities, and geotechnical consulting companies have studied the probability of a similar event recurring.

For this purpose, the Turtle Mountain Monitoring System was created. It is a near-real-time remote monitoring system that provides data from a network of sensors and monitoring campaigns. This system also includes a GBInSAR LiSAmobile system. The GBInSAR LiSAmobile system has been active since 2014, and after such extended use, this is the client’s opinion:

“Our Conclusions from Assessing LiSAmobile

We continue to use and evaluate the LiSAmobile and Ellegi’s reports. We believe the system is reliable with minimum downtime since June 2014. This service alerts us of rock movements in advance to anticipate and prepare for a potential slide, and the quarterly reports and displacement images from Ellegi analysts are consistently of high quality.”
