A government volcanologist says a rumbling volcano in central Indonesia has re-erupted, sending panicked residents racing down back to shelters. There were no immediate reports of casualties.

Surono, who uses only one name, says Mount Lokon, located on northern Sulawesi island, unleashed its powerful eruption at 10:35 a.m. Sunday, spitting hot ash and smoke more than 11,400 feet (3,474 meters) into the air.

Panicked residents -- some of whom were returning to their villages to tend to their crops and animals -- raced down back to government shelters.

Mount Lokon is one of about 129 active volcanoes in Indonesia. Its last major eruption in 1991 killed a Swiss hiker and forced thousands of people to flee their homes.
