Mount Lewotobi Laki-laki in Indonesia's East Nusa Tenggara province erupted on Tuesday, spewing a huge ash cloud 11 kilometers high, the country's volcanology agency said.
The agency also said it had raised the volcano's alert level to the most dangerous level, warning of possible lava flows if heavy rain falls.
The last eruption of Lewotobi Laki-laki was in May when authorities also raised the level to the most severe.
Images shared by the agency on Tuesday showed an orange cloud of ash in the shape of a mushroom that engulfed a nearby village.
It is not clear whether there were any flight disruptions. When Lewotobi Laki-laki erupted in March, airlines were forced to cancel and delay flights to Bali, including Australia's Jetstar and Qantas Airways.
Indonesia is located on the "Pacific Ring of Fire," an area of ??high seismic activity at the top of several tectonic plates.
