Two landslides triggered by heavy rains killed at least 11 people and left 19 others missing on Indonesia's Sumatra island, officials said on Sunday.

The National Disaster Management Agency said seven people were killed and three people were injured in a landslide in Agam district in West Sumatra province early on Sunday.

"At this point, seven people were found dead and three others were injured... and 18 were missing," agency spokesman Sutopo Purwo Nugroho said in a text message.

Fifteen houses were also buried by the landslide, he added.

Separately, a landslide caused by heavy rains late on Saturday killed four workers at a drilling site belonging to PT Pertamina Geothermal Energy in Kerinci district in Jambi province, the company said in a press release.

"The landslide killed four people, injured five people, and left one person missing. All victims were workers who were drilling," it said.

Floods and landslides are common in Indonesia, which is prone to frequent bursts of heavy rain.

Heavy rain in the capital Jakarta this month caused 32 deaths and at its peak forced nearly 46,000 people to flee their inundated homes, Nugroho told AFP earlier.
