BALI, Indonesia (AP) -- Warnings that a volcano on the Indonesian tourist island of Bali will erupt have sparked an exodus of more than 75,000 people that is likely to continue to swell, the country's disaster agency said Tuesday.
Authorities have ordered the evacuation of villagers living within a high danger zone that in places extends 12 kilometers (7.5 miles) from Mount Agung's crater. But people further away are also leaving, said National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho.
The region is being rattled daily by hundreds of tremors from the mountain, which volcanologists say indicates a high chance of an eruption. Mount Agung last erupted in 1963, killing about 1,100 people.
Evacuees are taking shelter at more than 370 sites across the island that include temporary camps, sport centers, village halls and the houses of friends and relatives.
Villager Wayan Merta said he was among the first to evacuate last week because his village, Selat, is just 6 kilometers (4 miles) from the summit.
"We have already sold our cattle, because we thought it was better than leaving them there for nothing," he said.
"My feeling is the mountain will erupt," he said. "But no one knows, we just pray."
Sutopo said it was "natural" that people outside the immediate danger zone are leaving. More than 500,000 people evacuated when Mount Merapi in central Java erupted in 2010, more than double the population in the exclusion zone around that volcano, he said.
In 1963, Agung hurled ash as high as 20 kilometers (12 miles) and remained active about a year. Lava traveled 7.5 kilometers (4.7 miles) and ash reached Jakarta, about 1,000 kilometers (620 miles) away.
"This is the heaviest test in my live and hopefully it will end soon," said Ketut Suliasih, a Selat villager.
She said evacuees are being treated well by the government and community, but like others she is fearful about the future.
"No eruption. That is my prayer. Otherwise, our farms would not be able to be planted again."
The mountain, 72 kilometers (45 miles) to the northeast of the tourist hotspot of Kuta, is among more than 120 active volcanoes in Indonesia.
Officials have said there is no immediate danger to tourists but ash fall from an eruption would likely force the closure of Bali's international airport. The island, famous for its beaches, surfing and elegant Hindu culture, had nearly 5 million visitors last year.
Shops and businesses in Amed, a string of traditional fishing villages with a panoramic view of Agung some 40 kilometers (25 miles) away, were open Tuesday and tourists were enjoying the scenery.
Indonesia, an archipelago of thousands of islands, is prone to seismic upheaval due to its location on the Pacific "Ring of Fire," an arc of volcanoes and fault lines encircling the Pacific Basin.
