8.73°S, 120.98°E; summit elev. 1559 m
All times are local (unless otherwise noted)
Since the decline in eruptive activity that occurred during 23 January-5 February 2001 (BGVN 26:01), variable seismicity has prevailed. Ash plumes were observed in February and March reaching 10-500 m above the volcano. The Volcanological Survey of Indonesia (VSI) reported varying amounts of seismicity (table 1). VSI has not reported new eruptive activity at Inielika since May 2001.

Geologic Background. Inielika is a broad, low volcano in central Flores Island that was constructed within the Lobobutu caldera. The complex summit of the 1559-m-high volcano contains ten craters, some of which are lake filled, 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. The first historical eruption of Inielika, a phreatic explosion that formed a new crater, did not occur until 1905 and was the volcano's only eruption during the 20th century. Another eruption took place about a century later, in 2001. A chain of Pleistocene cinder cones, the Bajawa cinder cone complex, extends southward to Inierie.
