Sadly, it appears that two quarry workers were buried by a landslide that occurred at L’Epiphanie, Quebec on Tuesday, 29 January, 2013. From the available video and photos at ctv.ca, it appears that sensitive clay failed near the quarry and flowed into the quarry, filling some part of the working pit and burying at least one truck.
In a recent (2012) post on this blog I had presented a draft manuscript describing a process for mapping landslide risk in eastern Canada associated with large landslides in sensitive clay. You can search the “landslides” or “draft manuscripts” sections of this blog to find that post, entitled “Sensitive Clay landslide risk in eastern Canada (DRAFT paper).”
The image below, previously prepared to show that the last fatal landslide in the study area (St-Jude in 2010) had occurred in an area mapped as high risk. Yesterday’s event at L’Epiphanie is also in an area of high risk.
The following two images show the quarry and landslide (to the right and background), followed by a close up of the buried truck and rescue operations, from ctv.ca.
