Police have released an aerial view of Friday morning's landslide at a landfill site close to Esch-sur-Alzette, which closed the A4.

The snap shows the full extent of the frightening landslide, which was at first thought to be a harmless shifting of earth.

From the photo, it appears that soil shifted around 30 metres at the site, which is a former slag dump.

A Lallange resident said that in recent months hundreds of trucks had been dumping rubble and construction waste on the hill.

The licence to use of the site for landfill will expire in 2015, the neighbour said.

The city authority of Esch-sur-Alzette warned that the section of the CR 106 road, between Esch-sur-Alzette and Mondercange, which was flooded by rubble in the landslide, will remain closed to vehicles and pedestrians for an indefinite period.

A security perimeter has been drawn up around the disaster zone in case of further landslides.

In the meantime, the Esch-sur-Alzette and Mondercange communes will analyse the stability of soil and draw up an action plan.
