I certainly hope they filed the proper Environmental Impact Reports and held an adequate number of Public Comment meetings and they damn well better have submitted Form twenty three zed niner one four in triplicate or heads will roll!

From the link that has a different video of the cliff collapsing
"This sequence of still photographs were captured just as a cliff section was collapsing on the beach of St Jouin Bruneval in Normandy (49.63907°N, 0.1490°E). My colleague, Pierre Pannet from the BRGM (French Geological Survey) office of Normandy had just been called in by the Maire of the district as a collapse had occurred the day before. When he got onto the beach, a new cliff section collapsed in front of his camera.
At this location, the cliff is made of something like 50 m of chalk resting on the Gault clay horizon. This clay unit is weak and impermeable. It must have kept a perched water table weakening the base of the chalk face. Rains have been particularly heavy in the last 12 months, though on July 15 the weather was fair and sunny. Note that the tide was just starting to rise again. Neither the rain nor the sea beating the base of the cliff can be considered as the direct cause of collapse. It is more likely that it is the slow flow of saturated clay that has initiated the rupture and a sudden acceleration of that slow slip that caused the chalk “towers” to collapse."
More info at the link above.

In case it was not clear, I did not mean to imply this collapse was arranged or planned by the government... I was attempting to be witty.
