Above average rainfall recorded in last five days in Sancheong county, where most deaths took place.
The nationwide death toll from heavy rainfall in South Korea has risen to 14, authorities said, as fears grow of more deaths, with 12 more people missing since the disaster began.
Two people died and four went missing in the resort town of Gapyeong on Sunday after a landslide engulfed houses and flooding swept away vehicles, the AFP news agency reported, citing government officials.
A woman in her 70s was killed when her house collapsed in the landslide, while the body of a man in his 40s was found near a bridge after he drowned, South Korea’s official news agency Yonhap reported.
Close to 170mm (6.7 inches) of rainfall was recorded in the area in Gyeonggi province, about 70km (40 miles) east of Seoul, early on Sunday.
But most of the deaths occurred in the southern county of Sancheong, which has seen nearly 800mm (31.5 inches) of rain since Wednesday.
Two bodies were found there early on Sunday during search and rescue operations, raising the number of deaths in the rural county of 33,000 to eight, with six still missing.
The adjacent county of Hapcheon received 699mm (27.5 inches) of rain, while the nearby county of Hadong got 621.5mm (24.5 inches).
Two of the 12 people reported missing were from the southwestern city of Gwangju, Yonhap said.
Yonhap also quoted authorities as saying they have registered 1,920 cases of flooded roads, soil loss and destroyed public facilities, and 2,234 other cases of damage to private property, such as buildings and farmland.
A total of 12,921 people have taken shelter across 14 major cities and provinces, Yonhap said.
South Korea typically experiences monsoon rains in July and is usually well-prepared. But this week, the country’s southern regions were hit by especially intense downpours, with some of the heaviest hourly rainfall on record, official weather data showed.
Scientists say climate change has made extreme weather events more frequent and intense around the world. In 2022, South Korea endured record-breaking rains and flooding, which killed at least 11 people.
