Four people are missing after a landslide buried three homes on a hillside Tlalnepantla, México state, Friday afternoon.

Enormous rocks and earth became dislodged from the Cerro de Chiquihuite, probably a result of recent heavy rainfall, some officials said.

Heavy equipment and trucks were on the scene shortly after to remove debris and assist emergency personnel in the search for survivors.

Three days ago, at least one resident of the area noticed six waterfalls had formed on the hill during heavy rains. And hours later, there was a 7.1-magnitude earthquake.

The Cerro de Chiquihuite (Chiquihuite Hill) is located on the boundary of Tlalnepantla and the Mexico City borough of Gustavo A. Madero.
