Résumé
In 1903, more than 30 million m3 of rock fell from the east slopes
of Turtle Mountain in Alberta, Canada, causing a rock avalanche that
killed about 70 people in the town of Frank. The Alberta Government,
in response to continuing instabilities at the crest of the mountain,
established a sophisticated field laboratory where state-of-the-art
monitoring techniques have been installed and tested as part of an
early-warning system. In this chapter, we provide an overview of
the causes, trigger, and extreme mobility of the landslide. We then
present new data relevant to the characterization and detection of
the present-day instabilities on Turtle Mountain. Fourteen potential
instabilities have been identified through field mapping and remote
sensing. Lastly, we provide a detailed review of the different in-situ
and remote monitoring systems that have been installed on the mountain.
The implications of the new data for the future stability of Turtle
Mountain and related landslide runout, and for monitoring strategies
and risk management, are discussed.
