The glow of an incandescent red lava ring in the crater of Mount Agung in Bali is clearly visible, as the likelihood of a major eruption on the popular holiday island continues to grow.
The orange glow burned over Mount Agung could be easily seen at night and in the thick column of ash that, according to the Indonesian disaster agency, was sent almost three kilometers (3 miles) into the atmosphere.
“We could see the magma tonight,” said Nyoman Karyiarsa, a resident of the village of Rendang, to the Guardian on Monday night. “From 7 p.m. until 8 p.m., we could see a bright red color from the crater, but it has not come out yet.”
The Rendang monitoring station registered strong and continuous tremors around 2 p.m. Tuesday in Bali, and the locals and journalists were ordered to evacuate. The last major eruption in 1963 was preceded by continuous tremors.
The Balinese volcano, the highest point on the island, has become increasingly restless last week, with the warning system raised to its highest level early Monday, as the nature of the eruptions has gone from being phreatic Steam. magmatic
Nearly 100,000 people in 22 villages within a six-mile red zone around the volcano have been instructed to leave immediately.
Karyiarsa said the refugees from the mountains were still fleeing to their village and had felt several tremors in recent days. “We’re right outside the red zone, but we can hear the roar of the mountain, and the ash is covering the leaves, if you do not wear a mask, you can feel it when you breathe,” he said.
Photos of Mount Agung at dawn on Tuesday showed a dramatic column of two shades of ash rising from the volcano. Spokesman Sutopo disaster agency Purwo Nugroho said on Twitter that the white column is derived from water vapor, while dark gray was produced by magma.

The vulcanologists warn that the main dangers of a large eruption are avalanches of rocks, dust and gas that can not escape, known as pyroclastic flows, as well as mud flows and ash fall.
In the current rainy season, authorities have emphasized the dangers of hazardous ash and fast-moving mud flows known as lahar, which collect rocks, ash and debris that result in thick tides that resemble wet concrete.
The continuous eruption of Mount Agung has interrupted the plans of thousands of travelers. Volcanic ash can affect aircraft engines, so the Bali airport closed on Monday and has not yet been reopened. The officers are evaluating the conditions every six hours.
Ash is falling predominantly in a southwesterly direction, the Indonesian disaster agency said on Tuesday, and is also being affected by the movement of tropical cyclone Cempaka on the Java coast.
The instruments to measure activity on Mount Agung were installed only after the last major eruption in 1963, making it difficult for volcanologists to compare historical data and predict the intensity of future eruptions.
