Two houses and parts of two others sank into a river in Nam Can District of the Mekong Delta province of Ca Mau on Wednesday.
No human lives were lost in the incident.
These houses were makeshift ones constructed along the river. The incident causes losses of VND140 million (US$5,987).
Local authorities rushed to the scene of the incident to support locals in saving their assets.
Du Minh Hung, secretary of the Nam Can District Party Committee, alongside a working team from the district, visited the victims the same day and encouraged them to work toward rebuilding their lives.
The district also gave each affected family VND3 million ($128) so that they could purchase necessities.
Ca Mau Province faces landslides each year between May and September, when river tides are low, drying out riverbanks.
Rainwater flows into the dry riverbanks and cause them to collapse.
The province experiences hundreds of riverside landslides each year, causing losses of tens of billions of Vietnamese dong for local residents. (VND10 billion = $427,967).
However, it is hard to relocate those facing a high risk of landslides to safer places owing to their customs of building houses along rivers.
