During 6-11 February, Inielika volcano remained active and the VSI reported no significant change in volcanic activity. An ash plume was observed rising 25-500 m above the volcano and there was a slight increase in the number of deep volcanic earthquakes in comparison to the previous week. The Alert Level at the volcano was reduced from 3 to 2 (on a scale of 1-4).
Geological Summary. Inielika is a broad, low volcano in central Flores Island that was constructed within the Lobobutu caldera. The complex summit contains ten craters, some of which are lake filled, in a 5 km2 area north of the city of Bajawa. The largest of these, Wolo Runu and Wolo Lega North, are 750 m wide. A phreatic explosion in 1905 formed a new crater, 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.
