As the Indonesian Volcanological Survey (VSI) specified in its latest bulletin, parts of the active lava dome of the volcano have recently (early June) grown higher than the northern crater rim, where it is cut by a valley extending to the northern feet of the stratovolcano. Therefore, potential continued growth of the dome poses the risk of rockfalls and pyroclastic flows reach the northern flanks, where a number of villages are located, namely Pasilulu and Talen. ...

New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater. ... [details]

The volcano might be entering a phase of reawakening. A seismic swarm of 49 low magnitude earthquakes and a pulse of volcanic tremor occurred on 4 June, INETER reported in a press release that day. ... [details]

VSI raised the alert level of the volcano on Flores, famous for its 3 differently colored crater lakes, from 1 to 2 ("normal" to "waspada", "watch") on a scaled of 1 to 4, after one of the 3 crater lakes turned from blue to white on 3 June. In addition, a strong smell of sulfur was noted by people from Pemo village a few kilometers south. ... [details]

An small eruption occurred last Sunday (2 June) at 8:43 am (local time), preceded by a rise in seismic activity reported by the local volcano observatory. An ash explosion produced a small rising 300-600 m and light ash fall at Gunung Tujuh about 20 km away. According to local news, the sudden eruption caused panik among inhabitants of Sungai Rumpun village and several evacuated their homes. Some climbers who were on the volcano at the time of the explosions returned unharmed. ... [details]

New activity seems to have started from Satsuma-Iwo-jima (Kikai) volcano. A steam / gas and possibly ash-containing plume has been observed on satellite images and a thermal anomaly was visible on recent MODIS satellite data. On yesterday morning's NASA Aqua satellite image, the plume from the volcano was about 70 km long to the SW. A thermal anomaly was visible already on images from 23 May. ... [details]

New ash emissions resumed at approximately 11:00 AKDT (19:00 UTC) this morning and were seen in satellite data and observed by pilots. The new ash plume was drifting SE at approx. 19,000 ft (6 km) a.s.l. altitude. AVO reported weak seismicity beginning at 10:57 AKDT and raised the Aviation Color Code to Orange. [details]
