Rescuers were searching yesterday for villagers left missing when part of a newly built dam broke in southeastern Laos, flooding the surrounding countryside and killing at least 20 people.
More than 6,000 people lost their homes when the dam gave way on Monday, flooding surrounding villages.
The exact number of victims was unclear. The official Lao news agency KPL said earlier that hundreds of people were missing, without providing details. More recent reports put the number missing in the dozens. KPL said yesterday that the death toll had risen to 19.
Photos and videos posted on social media showed people sitting on rooftops to escape the surging water, while others were carried to safety or rescued by boat. State media said helicopters were also being used to rescue people.
SK Engineering & Construction, one of two South Korean partners in the project, said the top of one of five auxiliary earth-fill dams at the project “got swept away” on Sunday night after heavy rains.
But Korea Western Power, which was due to operate the hydroelectric power plant after its completion, said problems first emerged Friday when workers discovered the dam’s center had sunk by 11 centimeters.
Repair work for the earth-fill dam was hampered by heavy rain and damaged roads, and the situation worsened on Monday as water cascaded out of the reservoir, flooding seven out of 12 villages in the area, SK E&C said. It was helping to evacuate and rescue residents while also trying to contain further damage.
The government declared the area a disaster zone and top officials rushed to the site, it said.
Continued heavy rain and strong winds forecast for the area could hinder rescue efforts, and risks from flooding persisted in the mountainous region.
Provincial authorities issued a call for emergency aid — clothing, food, drinking water, medicine, cash and other items — from the “party, government organizations, business community, officials, police and military forces and people of all strata.”
The International Red Cross said food was a concern because village food supplies were drenched in the flooding. It was arranging for water purification units to be sent to the area to ensure supplies of clean drinking water.
The presidential office in South Korea said President Moon Jae-in had ordered an emergency relief team to help with the disaster.
SK E&C sent its president to Laos and set up an emergency team in Seoul, South Korea’s Yonhap News agency reported.
The USD1.02 billion project encompassing several river basins in a remote corner of southeastern Laos is the first hydroelectric dam to be built by a South Korean company, and it was unclear how severe the damage would be to the overall plan. The dam was due to begin operating in 2019, with 90 percent of the power generated going to Thailand.
Shares of companies affiliated with SK E&C sank on Wednesday on concerns over potential costs for compensation and other financial setbacks from the disaster.
SK Discovery Co., SK E&C’s second-largest shareholder with a 28.25 stake in the builder, tumbled more than 10 percent to trade at its lowest level in more than three years. SK Holdings Co., the biggest shareholder in SK E&C with a 44.48 percent stake, fell 3 percent. AP
