Much of Sri Lanka has been lashed by heavy rain in recent weeks, with mudslide warnings issued.
"About 70 houses, 10 shops and three official residences are hit by the landslide," Disaster Management Minister Mahinda Amaraweera told local media.
Sections of several national highways have been washed away by the rains, AFP news agency reported.
The landslide hit the town of Haldummulla in Badulla, about 200 km (120 miles) east of the capital Colombo, on Wednesday morning.
One woman who survived told local media: "I was under the rubble and some people took me out... my mother and aunt have died."
In June, monsoons triggered landslides in Sri Lanka that killed at least 22 people and forced thousands from their homes.
