"Those who live outside the danger zone, we urge them to go back home and carry on with their daily lives", said Putu Widiada, head of the disaster mitigation agency in Klungkung district south of the volcano where some 22,000 people have fled.
Hundreds of tremors were recorded on Monday at Mount Agung, in an increase of volcanic activity.
"The governor of Bali has ordered that residents from 27 villages within unsafe zone, which account for about 70,000 people, must remain displaced", a statement from the agency reads.
It added that volunteers were helping to evacuate cattle from the danger zone. That, they say, is the area most likely to be devastated by lava, hot ash, and something called lahars, which are powerful mudflows that occur when huge amounts of rock and dirt combine with water.
A spokesman for the National Disaster Management Agency says, "the Bali governor has told evacuees from 51 villages that are considered safe to return home'".
As of Saturday afternoon (9/30) the numbers of evacuees has reached 143,840 people from 471 evacuation points in nine districts/cities.
A second Indonesian volcano has erupted while residents evacuated from the island of Bali anxiously awaited the eruption of local volcano Mount Agung.
There are more than 120 active volcanoes in Indonesia, made up of thousands of islands on the "Ring of Fire" of fault lines and volcanoes in the Pacific. Most are being taken away by boat, with others being airlifted to evacuation centers on Vanuatu's Pentecost and Maewo islands.
For the last few weeks, Bali's Mount Agung has been threatening to erupt.
The Indonesian Centre for Volcanology and Geological Hazard Mitigation said last Friday that remote satellite sensing had picked up new steam emissions and thermal areas within the crater.
The website said Indonesian authorities were on standby to divert flights in the event of an eruption.
