South Korea will remove a concrete structure at the runway of one of its southern airports, the scene of a plane crash that killed all but two of the 181 people on board last month.

South Korea's transport ministry said on Wednesday that it would remove the concrete embankment installed at Muan International Airport following last month's Jeju Air crash, its deadliest domestic air disaster.

The South Korean Transport Ministry announced on Wednesday that the concrete feature would be removed from Muan International Airport, according to Reuters. Most other international airports simply mount similar arrays on breakaway posts to allow planes to overrun the pavement across flat ground.

Scores of people were killed on Sunday when a passenger jet crash-landed at an airport in southwestern South Korea, with the aircraft careening down the runway on its belly before bursting into flames.

Seven airports will also have their runway safety areas adapted following a review of all South Korea's airports that was carried out after the crash - the deadliest in the country's history. The Jeju Air flight was bringing passengers home from Thailand after Christmas when it made an emergency landing at Muan airport and exploded after slamming into a concrete barrier at the end of the runway.

Authorities in South Korea will remove concrete navigation barriers at seven of the country's airports. A passenger plane collided with a barrier at the end of the runway at the Muan Airport in December,
