Six people are known to have died and it is feared that more people
may be buried, following a landslide in Valle del Cauca Province, Colombia, on Thursday 1 December 2016. The landslide hit a residential district in the city of Cali, destroying a number of homes. The
incident is reported to have happened following a period of heavy rain. Landslides
are a common problem after severe weather events, as excess pore water
pressure can overcome cohesion in soil and sediments, allowing them to
flow like liquids. Approximately 90% of all landslides are caused by
heavy rainfall.

other.
