Authorities are trying to determine what caused a Kansas grain bin to collapse and spill about 250,000 bushels of corn on the ground.

The Hays Post reports that no one was injured when the bin gave way around 11 a.m. Wednesday in the Morris County community of White City.

Morris County Emergency Management director Chris Blackledge says four elevator employees heard a loud commotion outside just before the collapse. The bin has a 500,000-bushel capacity.

Cleanup of the spill began on Thursday morning. Blackledge says Mor-Kan Grain owns the bin. A woman who answered the phone at Mor-Kan but declined to give her name told The Associated Press that would be no comment.
