context_page_description: The catastrophe du Boël was a landslide that occurred on June 6, 1884 in a quarry at a place named Le Boël in Bruz, Ille-et-Vilaine, in the west of France. The landslide killed eight people including two children. Groundwater that weakened the cliff and damage caused by explosives used to remove red shale from the quarry were the principle causes of the accident. The search to recover the bodies took five days.
  At the time, the event left its mark, probably because of the death of the children and because it impacted different social classes. Editors of several newspapers from Rennes collaborated and sold a magazine at 50 cents apiece to benefit the victims. Donation campaigns were also carried out by the local press.
context_section_description: Groundwater was a danger for the quarry workers because it weakened the cliff. It would thus be one of the causes of the disaster, in addition to the damage caused by the explosives used to extract the shale. Also, around 7:45 AM on the day of the incident, the quarry team leader had a borehole loaded, but although the wick was lit, there was no explosion. It is unclear, however, if the quarry workers loaded a new charge recklessly into the same hole or if a second borehole was put into action.
