Bali's international airport will re-open on Wednesday after a nearly three-day shutdown, Indonesian airport authorities say, as ash from a rumbling volcano that looms over the island paradise shifted direction. <br/><br/>The eagerly awaited decision opens up a window of hope for some of more than 1.20 lakh 2tourists stranded after a spike in activity at Mount Agung grounded hundreds of flights since Monday. <br/><br/>The majority of Bali's tourists are Chinese, followed by Australians, Indians, British and Japanese. Foreigners whose visitor visas are expiring will be given a special permit to stay longer due to the eruption. <br/><br/>Agung rumbled back to life in September, forcing the evacuation of thousands of people living nearby. <br/><br/>Indonesia, the world's most active volcanic region, lies on the Pacific Ring of Fire where tectonic plates collide, causing frequent volcanic and seismic activities.
