Background
The complex summit of 1559-m-high Inielika volcano contains 10 craters, some of which are lake filled, located in a 5-sq-km area north of the city of Bajawa. The largest of these, Wolo Runu and Wolo Lega North, are 750 m wide. A chain of cinder cones, the Bajawa cinder cone complex, extends southward to Ineri volcano.Significant volcanic eruptions: Inielika volcano

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Eruptions of Inielika volcano
1991 eruption
Inielika volcano erupted between 11-16 January 2001. Numerous explosions, some with thundering sounds audible up to 8 km away produced ash plumes that reached heights of 1 km above the volcano, causing light ash fall in the immediate surroundings up to ca. 10 km distance.
2 new craters were formed by the (phreatic?) explosions, the larger one to the SE 50 m wide and 10 m deep, and a smaller crater to the NW 20 m wide and 1 m deep.
