At least 30 homes collapsed in the landslides near the city, which lies west of the capital Bogota.
The landslides hit after the equivalent of a month of rain fell in a single night. Local authorities said the city was cut off by rocks, mud and floods.
More than 300 people were killed in landslides in the southern Colombian town of Mocoa earlier this month.
