The governor gave his assurance during a meeting with tourism stakeholders, such as travel operators, here on Tuesday.
If Mount Agung erupts, it would have direct impact only on 28 villages located within a radius of 12 kilometers from the volcanos crater.
Balis main tourist attractions such, as Nusa Dua, Kuta, and Sanur, are located tens of kilometers away from the location of the mount, he added.
According to him, Karangasem has 78 villages, and only 28 villages could be directly impacted. The remaining 50 villages and other tourist destinations in Bali would be safe.
"Therefore, do not hesitate to visit Bali, except for climbing the mount, which will be forbidden as it is dangerous," Pastika explained.
Besides, the current condition is different from how it erupted in 1963.
Indonesia now has better disaster mitigation measures and more sophisticated information technology that could minimize the number of casualties and damages in case of eruption, he asserted.
More than 4 million foreign tourists visited the resort island of Bali in the first eight months of this year, up 25.40 percent from 3.19 million in the same period last year.
"Therefore, I would like to reaffirm that Bali would be safe and there is nothing to be worried about. All arrangements have been already made in case of an eruption," he reiterated.
The government has planned to hold a meeting with foreign consuls in Bali in order to eradicate misinformation and disinformation or hoax regarding the current situation.
Meanwhile, in August 2017 alone, 601,884 foreign tourists visited Bali, a 37.37 percent increase compared to the same month last year, Chief of the Central Statistics Agency (BPS) office in Bali, Adi Nugroho, remarked here on Tuesday.
