The death toll in the Pettimudi landslide climbed to 63 on Thursday with the recovery of an unidentified woman's body while a search is on for seven missing people.
The remains were found near a river bank at Puthukuzhi, about 14 km, from the landslip site, an official press release said.
Two ground-penetrating radars (GPR) from Chennai was also being used for the search operations.
A massive mound of earth and slush triggered by heavy rains had flattened a row of 20 one-room houses on August 7.
The houses made of tin and asbestos were inhabited by at least 82 tea plantation workers.
