Narrative:

Aircraft X ground looped as he attempted to depart runway xx. I saw aircraft X taxi onto runway xx; but I did not see aircraft X ground loop as I was continuing to scan down the runway along the departure path. After ground control advised aircraft X was off of runway xx on the south side; I advised all aircraft to go around. I then started sequencing all aircraft in the pattern to make a full stop landing on runway xy or to depart the pattern.as I continued to clear aircraft to land; the controller in charge (supervisor) advised me the field was now closed. Therefore; I had to advise aircraft that had previously called me inbound that they had to exit the airspace as the field was now closed. I wasn't expecting the field closure; and I am not sure if I was expected to have all of the aircraft exit ZZZ airspace. There has not been time today to confirm what the expectation was as far as aircraft in the pattern and / or inbound.ground loops can be accidents if perhaps an aircraft has a prop strike or ends up with significant damage. However; please clarify if the expectation is to close the field even for ground loops that may not necessarily result in significant damage.
