The governor, Mr Somsak Changtrakul, posted on his Facebook page today dismissing the reports carried by several local media today.
He said Pha Taem cliff which is near the Pha Taem national park did not collapse and the paintings were not damaged.
In fact, he said, the cliff that did collapse is six kilometres away from Pha Taem cliff.
The cliff is located in Talong village, while Pha Taem is in Nong Phue Noi village near Pha Taem national park.
He said the 50-metre long and 40-metre wide cliff stretch of the cliff crumbled 6-10 metres below, but cause no injuries to lives.
However he said he did not ignore the collapse of the cliff as the geological formation of the collapsed cliff is similar to Pha Taem which is formed by shale rocks and sand stones.
He said he had informed the Fine Arts Department and the Mineral Resources Department, who would examine the entire cliff as a precaution to save the Pha Taem cliff and as a safety concern of tourists as they have same rock formation.
According to Bangkok Post, The Pha Taem national park is part of Phanom Dongrak mountain and at its highest point is 600 metres above sea level and covers an area of 140 square kilometres.
Deep down the cliff on the park’s east face flows the Mekong River that separates Thailand and Laos.
The prehistoric paintings on Pha Taem cliff dated back 3,000-4,000 years.
The assortment of more than 300 prehistoric paintings spread along a 180-metre stretch of the cliff.
It is the largest such collection found in Thailand, variously depicting animals, human hands, spiritual rites, farm activities and hunting scenes.
The rock paintings, combined with the natural beauty of the area, have made Pha Taem a major tourist attraction of the province.
