<p>  The city of Busan estimates that the 38-year-old road floor has been damaged by the long-term collapse of the accident. </p>
<p>  The chasm was found in the form of a pot 3.5 m wide, 3.5 m deep and 3.5 m deep, and was dug into the ground. </p>
<p>  There was no sign of being washed off the ground or soil. </p>
<p>  In addition, there is no water and sewer line around the point of accident and no trace of groundwater leakage. </p>
<p>  In the case of sinkholes that have occurred in other areas in recent years, there have been many cases of groundwater loss due to water discharged by groundwater or water pipes. </p>
