Indonesia's Mount Lokon volcano on Sulawesi island erupted on Sunday (October 7) spewing hot ash into the air.
Indonesia's volcanology agency reported the eruption occurred at 3:05 am EST. The volcano in the eastern part of Indonesia has erupted 41 times since September 1 and the eruption on Sunday is the largest so far.
Local Antara news agency said the government has set a safety radius of about 1.5 miles from the crater. The agency also said Lokon is now the most active volcano in Indonesia.
Residents have asked to stay at home but some were preparing to evacuate due to breathing difficulties, according to Metro TV, which showed footage of plumes of hot ash rising into the sky.
Indonesia sits astride the geologically active Pacific "ring of fire". It has more than 100 active volcanoes.
