No injuries are reported but a lot of corn is on the ground after two grain bins collapsed at a northwest Kansas elevator.

The exterior walls of the two concrete bins at one end of Frontier Ag Inc.’s elevator annex in Oakley gave way around 2:30 p.m. Tuesday.

Emergency personnel said all employees were accounted for.

Frontier Ag grain marketing manager Ben Brandvik says each bin could hold about 25,000 bushels when full. He said the far end of the elevator was not very full when the walls crumbled, although a witness reported seeing a large of amount of spilled corn.

Brandvik says insurance adjusters are surveying the damage to determine when it will be safe to start cleanup. The cause of the collapse is under investigation.
