These include the Alexandra Community Centre hall, Poolburn’s pavilion and hall, Clyde Railway Station and the Omakau and Ophir halls.
Central Otago District Council property and facilities officer Tara Bates said the buildings had undergone an initial assessment in 2013.
The assessments showed buildings ranged from about 21% to 40% of new building standard (NBS).
Ms Bates said buildings less than 34% NBS were defined as ‘‘earthquake prone’’.
Central Otago emergency management officer Matt Alley said the Alexandra Community Centre hall and theatre was identified as a civil defence centre.
This would mean it was a ‘‘priority’’ building and if it was to continue to sit in the emergency management plan it would need to be strengthened to about 67% NBS or higher.
The aim was to have at least one priority building in the main towns of Roxburgh, Alexandra, Ranfurly and Cromwell, he said.
The Alexandra hall was about 21% of NBS and the theatre about 38%.
The board also voted to agree to a district-wide risk management policy under which discretion to decide to close a council-owned earthquake-prone building would rest with the council rather than the board.
A notice on the community centre hall informed visitors the building had been assessed as earthquake prone, but was structurally sound in normal conditions.
Ms Bates said the council was putting earthquake prone notices on buildings that already had a detailed seismic assessment to confirm the status was below 34% of the new building standard.
‘‘We are being proactive prior to the official notices being issued by council as territorial authority,’’ she said.
