No casualities were reported.
The volcano spewed volcanic ash and lava and Gurukinayan residents were moved to a safe area, The Jakarta Post reported.
Jhonson Tarigan, an official of the Karo Regency, said Gurukinayan was covered in ash.
"Mount Sinabung's strong eruption today unleashed volcanic ash, pyroclastic clouds and blazing lava, threatening residents in its nearby villages, including Gurukinayan. We evacuated them all," Jhonson said.
Gurukinayan is outside of Mount Sinabung's "danger zone," Jhonson said.
"It was the first village beyond the 3-kilometer [about 2-mile] radius that was evacuated," Jhonson said. "This shows Mount Sinabung's eruptions have become even worse as the volcanic ash has reached villages outside the danger zone."
Mount Sinabung began erupting two weeks ago and authorities evacuated five villages that are within the danger zone.
