An investigation is under way after part of a disused mine collapsed in Co Monaghan.
A local school was evacuated and some playing fields at a nearby GAA club subsided.
An exclusion zone has been set up around the mine as a precautionary measure.
A spokesman for Magheracloone Mitchells GAA club said the club's ground, community centre and pitch is completely out of bounds.
Assistant PRO Jim McMahon said the damage is being assessed but nobody was hurt.
He said the collapse was on the club's land and an investigation is under way by the company that owns the old mine.
Pictures on social media showed large cracks in the clubhouse and the surface of the club's pitch.
It was reported that Drumgossatt National School was evacuated and parents were asked to collect their children.
Gardaí confirmed they were at the scene of an incident in the area.
In a statement, Monaghan County Council said the subsidence occurred overnight and that a section of the main Carrickmacross/Kingscourt road (R179) will remain closed over the next 48 hours with diversions in place.
The mining company Gyproc has said its initial assessment of the area which subsided yesterday is confined to a radius of 120 metres.
In a statement the company said five properties located at the perimeter of the exclusion zone are being examined to determine if there is any risk arising out of the subsidence.
It said their assessment also indicates that all areas outside the 2km zone are unaffected. Including the Drumgossatt National School which re-opened today.
Gyproc is a subsidiary of Saint-Gobain Ireland and mines gypsum for the manufacture of plasterboard.
A meeting between Monaghan County Council, gardaí and the mining company is due to take place later.
Geologists from the Department of Communications and Natural Resources carried out risk assessment earlier today.
The exclusion zone is still in place and traffic diversions remain in place.
