Mount Lewotobi Laki-Laki on Flores Island erupted at 11:15 a.m., sending volcanic material 2.5 kilometers into the air, the national volcanology agency said in a statement. It came after several other eruptions earlier on Friday.
Lewotobi Laki-Laki falls under Indonesia's second-highest alert level for volcanic activity, with a five-kilometer exclusion zone in force around its crater.
The volcanology agency said residents near rivers should also remain on alert for hazardous floods of volcanic material, known as lahar, if heavy rain occurs.
Authorities have suspended operations at a local airport in the town of Maumere, about 60 kilometers west of Lewotobi Laki-Laki, affecting five domestic flights, airport head Partahian Panjaitan told AFP.
