AbstractAlong the coast of the Gaspé Peninsula, in Quebec, Canada, a railroad runs directly across an active rockslide involving a volume of 0.5Mm³. A near real time monitoring system has been installed in 2009 and 2010 in order to develop an early-warning system. After more than a year of data acquisition, an overall seasonal trend has been observed, with slower movements in the summer months and acceleration in fall through early winter. Information acquired by the monitoring system and other sources enables the evaluation of the failure surface geometry with good confidence.
