There were no casualties, but the water supply pipe was broken. As a result, people's anxiety and concern are serious. It is presumed that it was caused by the outflow of groundwater from the construction site of the Hayang double-track railway.

The movie "Sinkhole" was released on the same day. It is a disaster movie about a large sinkhole. It's a movie that has a lot of empathy. Audiences feel like a real situation, and it's easy to watch due to the comedy scenes.

It is difficult to predict when a sinkhole will occur. Therefore, it is necessary to prevent accidents in underground spaces. The government has set up a special task to come up with safety measures.

They include integrated underground map construction service, strengthening safety management around excavation sites, preemptive monitoring and management of unstable factors, and finally establishing an underground space safety management system.

Accidents in underground spaces such as sinkholes do not occur in an instant. Damage can be minimized by identifying the aging ground and preparing for accidents. Even now, it is necessary to make efforts to prevent movies from actually happening.
