Step Vaessen, Al Jazeera's correspondent in Jakarta, said that landslide had been caused by rain water and compounded by deforestation in the area.
"The city of Bandung and the surrounding areas have been covered in rain water for the last couple of weeks," she said.
"It's been a very big landslide and hope is running out for the people who are buried under the rubble.
"The road has been cut off, the phone lines have been cut. What I've been told is that there are only a few soldiers; some local rescue teams but heavy machinery has still to arrive.
"It's already dark and they have just told me that they're going to work through the night to try to save more people. But it's going to be very difficult to find people alive there now."
Thousands of people have been forced out of their homes by flooding in Bandung and Jakarta over the past two weeks.
Antara said some parts of Bandung district have seen the worst flooding in eight years, inundating some 10,000 houses.
"The floods have now started to subside. Related authorities are now preparing to tackle the potential of post-flood diseases," a Disaster Mitigation Agency official told Antara.
Many of the floods and landslides which hit Indonesia every wet season are blamed on rampant illegal logging and unchecked development in water catchment areas.
Twenty five miners were killed in a landslide on Sulawesi island in October, 2008.
In July, 2007 more than 130 people were killed in floods and landslides on the same island.
