Mount Agung in Bali is experiencing unprecedented levels of seismic activity and could erupt in a "matter of hours" if tremors continue, Indonesia's volcanology centre has said.
More than 75,000 people have been evacuated in the last few days as Agung, the highest point of the island, has experienced hundreds of internal volcanic earthquakes. "Instrumentally we have never recorded such high energy or seismicity from Mount Agung," Devy Kamil Syahbana, a seismologist from Indonesia's centre for volcanology and geological hazard mitigation, told the
Guardian.Data showed that Mount Agung experienced
844 volcanic earthquakes on Monday, and 300 to 400 earthquakes by midday on Tuesday, he said. "We need to pay attention because these kinds of earthquakes indicate the movement of magma and increase the probability of an eruption."
Evacuated people have sought shelter in hundreds of village halls and sports centres and in the homes of relatives in more than nine districts. President Joko Widodo is scheduled to visit evacuees at several camps on Tuesday. Authorities have urged people to stay out the danger zone, a designated five-to-seven-mile radius of the volcano.
The increasing frequency of deep and shallow volcanic earthquakes, as well as local tectonic tremors, is an indication that magma continues to move toward the surface.
The alert status of Agung was raised to the highest levelon Friday evening following a significant spike in seismic activity. Kasbani, the head of the volcanology centre, told local media that if tremors continued, an eruption - the first in more than half a century - could be a "matter of hours" away.
Comment: Meanwhile Bali volcano evacuees from outside the 'danger zone' have been told to return home. Bali Governor I Made Mangku Pastika said it had only been necessary for about 70,000 people from 28 villages to have evacuated - about half the total number of 141,399 evacuees.
Mount Agung, a volcano in eastern Bali, has been on the highest possible alert since September 22, after intensifying seismic activity pushed molten rock known as magma towards the surface.
