Recent heavy tropical rain was a likely factor in a deadly landslide in northwestern Colombia.

The catastrophic failure of a steep slope above a main road west of Medellin happened on Monday.

News media reported that the slide wiped out six homes. It also swept away an undetermined number of people on the road, who were transferring from one bus to another.

Officials estimate the number of missing people believed to be trapped within the rubble is 20 to 30, reports said.

The site of the slide, Antioquia province, is mountainous with many steep, potentially unstable slopes.

Normal monthly rainfall at this time of year varies from 5 to more than 10 inches across the area. At the time of the landslide, up to 5 inches of rainfall within 24 hours was observed in and near Antioquia.

Local authorities feared further failure of unstable slopes, and the affected main road was shut to all traffic.


Rescue workers dig for survivors at the scene of a mudslide in Giraldo, in Colombia's northwestern Antioquia state, Tuesday, Sept. 28, 2010. Rescue officials said it will take at least a week to unearth about 30 people who were buried by a landslide as they changed from one bus to another because a mountain road was blocked. Heavy rain in recent weeks across Colombia has triggered flooding that has claimed at least 74 lives. (AP Photo/Luis Benavides)
