BALI — The Mount Agung volcano on the Indonesian tourist island of Bali spewed ash and smoke on Tuesday (Nov 21), but authorities said its alert level remained unchanged.
National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said the minor eruption began at about 5pm and clouds of smoke rose about 700m from the volcano.
Bali's international airport remained open.
Agung’s alert status was recently lowered to the second-highest warning level after several weeks at the highest level.
More than 140,000 people evacuated the region around the volcano when it was at the highest alert level, though authorities urged some to return home as they'd left areas not in the official danger zone.
The number of evacuees dropped to about 30,000 after the alert level was lowered.
Mr Nugroho said people should stay out of an exclusion zone that in places extends 7.5km from the volcano.
He said there hasn't been an increase in seismic tremors from the volcano. An escalation in tremors can indicate magma is rising inside the mountain.
New Zealand volcanologist Dr Janine Krippner tweeted that the eruption is “not serious”, but warned that “this can change”.
“Time to make sure you are prepared and keep an eye on official Agung information.”
The 3030m Mount Agung is among the more than 120 active volcanoes in Indonesia. It last erupted in 1963, hurling ash high as 20km and remained active for about a year. Lava travelled 7.5km and ash reached Jakarta, about 1,000km away.
Indonesia 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. AGENCIES
