Vice Governor Somkiet Sangkaosutthirak and the Director of the Damrungtam complaints office, Praphan Kanprasang, led a deputation yesterday that looked at work being carried out below the monument.
With them went local authorities, including village chief Peachkarn Patkor, and officials from the Forests Department and the Department of Disaster Prevention and Mitigation.
Authorities said they believed parts of the slopes below the Big Buddha appeared high-risk when it came to potential land slips.
Vice Governor Somkiet said that Phuket supported the religious aspects of the monument's construction but was concerned as development continued downwards, below the giant statue, into public areas.
Suporn Wanichkul, who set up a foundation, now known as the Mingmongkol Faith 45 Foundation, to construct a big buddha in 2002, said construction would be halted while the safety risks were reviewed.
The project appears to be under continuous construction with funds still being solicited from the hundreds of tourists who visit the hilltop each day.
