VSI reported that during 16-23 April seismic activity increased at Inielika in comparison to the previous week. Seismographs recorded five deep volcanic, ten shallow volcanic, and eleven tectonic earthquakes. Inielika is at Alert Level 2 (on a scale of 1-4). The previous report of significant volcanic activity occurred on 11 January 2001 when minor explosions began.

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.
