The damage is reportedly worse than last year’s quake.
Local authorities and officials of a local disaster prevention and mitigation office surveyed many important archaeological sites Tuesday.
They found many temples have cracks.
One of them, Wat Phumin temple has many cracks on the inside and outside of its Buddha image hall.
Other slightly damaged archaeological sites include Wat Phrathat Chang Kham and Wat Phrathat Khao Noi located on a hilltop.
People living on high-rise building in the province are warned to be more cautious due to a possible new round of earthquake.
The Fine Arts Department is also inspecting the damaged archaeological sites in the Nan municipality area.
