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.

7 February-13 February 2001

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).

31 January-6 February 2001

The VSI reported that during 23-29 January no explosive activity occurred, but a plume of white ash rose 100-500 m above the crater. The volcano remained at Alert Level 3 (on a scale of 1-4).

17 January-23 January 2001

The VSI reported that during 16-22 January ongoing explosions sent ash 100-1,000 m above the crater rim. Ash was deposited within a 10-20 m radius around the crater; lapilli with a maximum diameter of 50 cm were deposited out to ~500 m around the crater. Observations on 21 January revealed that two new large craters formed, to the SE and the NW. The SE crater was 50 m in diameter and 10 m deep. The NW crater was 20 m in diameter, open to the NW, and 1.1 m deep. The volcano remained at Alert Level 3 (on a scale of 1-4).

10 January-16 January 2001

A minor explosion on 11 January 2001 at 1915 produced an ashfall deposit less than 0.5 mm thick in Bajawa (~8 km from the source). On 13 January 2001 at 0700 three explosions occurred, sending a plume ~300-1,000 m above the crater rim; it moved eastward towards Toa village and southward towards Boya village, Bajawa, and Bolodio city. Thundering sounds were heard from the observatory (~7.5 km from the summit). Continuous tremor was recorded with an amplitude of 2 mm and 59 explosion earthquake events had been registered as of 15 January. Inielika is at Alert Level 3 (on a scale of 1-4).

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 Ineri.
