The volcano spewed a column of ash at a height of up to 250 meters from the mountain`s top, Darno Lamane, head of the Mount Gamalama observation post, stated here, Thursday.
Wind drifted volcanic ash of the mountain toward northwest, and the ash fell on West Ternate Sub-district.
Despite the eruption, the volcano`s emergency status remains at second level. Some 1.5-kilometer radius from the crater is closed to the public, including climbers.
Lamane also appealed to people living along sides of the rivers whose upstream are close to the volcano area to remain vigilant of potential threats in the form of lava flows during the current rainy season.
