History of eruption;
  • 1905; The explosive eruption that lasted for 5 hours. According to Neumann van Padang (1951) the eruption was semi-magmatic, with volcanic material released striking the northeast, an area of ​​106,800 m2 (Kusumadinata, 1979)
  • 1921; Small ash eruption that occurred on 1.3, and 4 January. Ash falls in Larantuka and in  Lomblen island. The ash eruption also occurred on December 20 accompanied by a stone throw. Ash until it reaches 12 km distance. Suspected activity of the year associated with the formation of lava dome contained in the crater B.
  • 1935; Not specified clearly this year’s eruption. Reported smoke thick out periodically every 5 minutes from crater B accompanied by a roar.
  • 2001, January 11, 2001 at 19:15. Blasting ash blown southward to Bajawa city which is 8 km from the center of the eruption, with a thickness of 0.5 mm. This ash eruption lasted until January 16, 2001 with bursts of ash ranging from 100 – 1000 m above the crater lip.
    The powerful eruption of mt. Inielika that occurred in 2001 and centered on the western crater resulted in the formation of 4 new crater holes.
Elevation (meters above sea level);
1.559 m (5.115 ft)
Type of eruption;
Eruption mt. This is either explosive or effusive, the eruption usually does not last long. Early eruptions were discovered in 1905 and a new eruption back in 2001. Based on these events, mt.Inielika has the shortest eruption period of 16 years and the longest to 96 years.…
Topology & Geology;
Kusumadinata, S., (1997), mentions that the geological history of Bajawa and surrounding areas begins since the Middle Miocene. The tectonic position of this area includes into the back basin of the arc (back arc basin). Sandstone with limestone lenses, inserted in napal and breccia known as Nangapanda Formation, is deposited in this area, and then followed by volcanic activity shown by the presence of dasitis, andesitis and basaltic rock groups. At the same time, precipitated limestone cones with sandstone limestones and sandstone sandstone from the Tray Formation are deposited.
At the late Middle Miocene Kala, the region undergoes lifting, folding and enlargement resulting in geologic structures north-northeast and northwest-southeast, followed by granodiorite and quartz diorite breakthroughs in existing formations. During the late Miocene Kala up to the Early Pliocene, this area has decreased and deposited rocks from the Waihekang Formation and Kedindi Formation. At Kala Plio-Plistosen the basin is raised and folded strongly at the time of the Pliocene End or Early Plistocene followed by volcanic activity that produces volcanic composition andesit. The entire Flores region is lifted by the formation of land at the end of the Plistocene, followed by the enlargement, folding and reactivation of existing faults.…
