The official alert level of the volcano was lowered back to "normal" on 7 Oct. The Lewotobi Laki-Laki stratocone been showing signs of unrest (increased volcanic earthquakes during March-May this year), but seismic activity has since then returned and remained at normal background levels. [details]
Tuesday, Sep 01, 2015
PVMBG reported that white plumes were observed rising 15 m above Lewotobi during periods of clear weather from 17 July to 25 August. Seismicity decreased significantly during 1-25 August. The Alert Level was lowered to 1 (on a scale of 1-4). [details]

HeureMag. / DepthDistanceLocation
Lewotobi volcan à l'extrémité orientale de l'île de Flores est l'un des volcans les plus fréquemment actifs dans la région. Il a deux pics disposés sur une ligne NW-SE séparés par 2 km et 1232 m d'une selle haute. Cela a donné le volcan jumeau son nom Lewotobi "mari et femme» (également orthographié Lewetobi).
Les deux pics correspondent à la Lakilaki Lewotobi et Lewotobi stratovolcans Perempuan. Lewotobi Lakilaki (1584 m) a un cratère sommital de 400 m de diamètre ouverte vers le nord. Cratère Lewotobi Perampuan (1703 m) l 'est de 700 m de large.

Introduction:

Lewotobi Lakilaki has been frequently active during the 19th and 20th centuries, while the taller and broader Lewotobi Perempuan has erupted only twice in historical time. Small lava domes have grown during the 20th century in the summit craters of both volcanoes. A prominent flank cone, Iliwokar, occurs on the east flank of Lewotobi Perampuan.

2003 eruption
Lewotobi volcano erupted on 30 May 2003. Ash plumes were seen 200 m above the summit and light ash fall occurred at the observatory 5 km from the crater. Small eruptions continued in June and July, producing ashfall in the villages of Bawalatang, Duang, and Boru.
On 31 August, a more powerful explosion produced an ash plume to a height of ~2.5 km above the summit that drifted W, incandescent lava bombs ignited forest fires up to 1 km radius from the crater. Ash fall damaged crops on nearby farmland. Following that 2003 eruption, according to the daily Jakarta Post, at least 565 villagers living on the slopes of Lewotobi were affected by sulfur and ash emissions. The residents experienced respiratory problems and skin afflictions.
The eruption ended sometime in October.

2002 eruption
An moderate explosion occurred at the volcano on 12 October 2002, the first activity since 1999. ...plus

1999 eruption
Small ash explosions began at Lewotobi volcano on 21 March 1999.
The activity consisted typically of weak steam and ash emissions reaching a few 100 m above the summit, sometimes interrupted by more powerful explosions. In April and May, mild strombolian activity with visibly incandescent lava was observed, ejecting bombs to 50-75 m above the crater. A stronger explosion, accompanied by a blast, occurred on 1 July 1999. The explosion threw glowing bombs to more than 500 m distance from the crater, igniting forest fires that burnt vegetation up to 2.5 km north of the volcano. Minor ash fell occurred in an 8 km radius, including the villages of Boru, Bawalatang, and Watukubu.
No reports of further activity after July are available, when the eruption probably started to die out.

1991 eruption
Mild eruptive activity resumed at the summit crater in the first half and until around July/August of 1991. Mild ash emission and strombolian activity was observed between March-July. The highest reported ash plumes reached about 800 m and incandescent material reached 100 m height above the crater. It was reported that hot ash fall (smelling of sulfur) onto nearby areas caused residents to flee during eruptions in July.

1939 eruption
Lewotobi volcano erupted on 17 December 1939, exactly 6 years after the start of the previous eruption. It is reported that the eruption caused lapilli fall "like hen eggs" at the Hokeng mission post for 10 minutes.

1933 eruption
A powerful ash eruption occurred at Lewotobi volcano on 17 December 1933. Incandescent bombs were visible from Doeang and Nobo.
