A sinkhole swallowed bleachers, a light pole and 100 feet of soccer fields at Gordon Moore Park in Alton, Illinois on Wednesday.

Surveillance video showed the moment the sinkhole opened up and an area where benched players would sit during games disappeared beneath the earth.

Mayor David Goins said no one was hurt in the collapse at Gordon Moore Park, and that Alton Parks and Recreation Director Michael Haynes was at the scene to assess the damage. Goins also said geologists are helping with the assessment.

Haynes said the hole is approximately 100 feet wide and 30 feet deep. No one was using the field at the time of the collapse.

The sinkhole was reportedly the result of an underground mine owned by New Frontier Materials, a spokesperson for the mine told 5 On Your Side.

"The impacted area has been secured and will remain off limits for the foreseeable future while inspectors and experts examine the mine and conduct repairs," the New Frontier Materials representative said. "No one was injured in the incident, which has been reported to officials at the Mine Safety Health Administration (MSHA) in accordance with applicable regulations. Safety is our top priority. We will work with the city to remediate this issue as quickly and safely as possible to ensure minimal impact on the community."

5 On Your Side crews are on the scene. This article will be updated with the latest information as it is released.
