Semeru volcano news & eruption updatesWed, 25 Jul 2012, 07:58  The active lava dome inside Semeru's summit crater as seen on 19 July (Photo: Andi / VolcanoDiscovery) The lava dome of Semeru volcano, East Java, is active and growing slowly our recent expedition group observed on 18-19 July during our trekking tour Volcanoes of Java. Read more...There is an area of incandescence visible at the SW part of the dome inside the half-open summit crater, and it is producing regular small to moderate ash explosions. Ash venting and small explosions had resumed in 2011. [ less] Tue, 8 May 2012, 10:05 CVGHM reported that during 1-29 February multiple pyroclastic flows from Semeru traveled 500 and 2,500 m into the Besuk Kembar and Besuk Kobokan rivers (on the S flank), respectively. During 1 February-30 April dense gray-to-white plumes rose 100-500 m above Jongring Seloko crater and drifted W and N. Incandescence was visible up to 50 m above the crater during 1 February-31 March. Seismicity decreased from March to April. Observations indicated that the lava dome grew in April. On 2 May CVGHM lowered the Alert Level to 2 (on a scale of 1-4) and reminded the public not to approach the crater within a 4-km radius.

Mon, 6 Feb 2012, 11:30 A slight increase in activity of Semeru volcano's activity has been observed by the Indonesian Geological Survey in recent weeks and its alert level was raised to 3 (out of 4, "watch") on 3 February 2012, after it had been on level 2 since 16 July 2009. Read more...Only small to moderate eruptions had been occurring over most of the past year. Between 29 December and 15 January, 8 explosions were counted which produced ash clouds up to 600 m high. One explosion threw incandescent bombs to a distance of 300 m from the Jonggring Seloko crater. During 15-29 January, only weak explosions were recorded and a small steam and ash plume rising 25-50 m was observed. Between 30 and 31 January, 5 explosions were recorded. They produced incandescent fallout in up to 400 m distance. On 2 February at 07:47 local time, a stronger explosion produced incandescent bombs that reached 750 m distance and caused a small avalanche of blocks rolling down a distance of up to 2.5 km (note: no pyroclastic flows). The heightened activity triggered the raise in alert level the following day. [ less] First visit to our site?
