Seven people died and one was injured Monday in an enormous avalanche of mud and rocks that buried a house in Herveo, a town in the west-central Colombian province of Tolima, authorities said.

Of the fatalities, two were minors, Herveo Mayor Fermin Gallego told the media.

Gallego called on authorities and emergency management services to send a helicopter to transport the injured man and the bodies, since, he said, "there are no roads" in the region due to mudslides caused by the torrential rains that have virtually immobilized parts of Colombia in recent months.

Firefighters and rescue teams were sent from Ibague, the provincial capital.

All the victims were siblings and cousins sleeping in the house after attending a graduation party, the mayor said.

Other regions of Colombia were also hit by emergencies caused by heavy rains over the past few days.

A wide area of the Sabana de Bogota plains in the central part of the country was put on maximum alert Sunday when the Bogota River overflowed and flooded hundreds of hectares (acres) and shut down highways to the capital.

From Sept. 1 to Dec. 1, some 114 people died as a result of the rains lashing the Andean nation, Colombian Red Cross official Cesar Ureña told Efe.

The current rainy season began less than six months after an unprecedented year-long deluge that left more than 440 people dead and roads, bridges and hundreds of homes destroyed.

At the same time thousands of hectares (acres) of cropland were flooded and thousands of head of livestock drowned.
