Strombolian activity in Semeru seen in mid Sep 2014 (photo: Andi / VolcanoDiscovery)
Our recent tour group on Java observed mild ongoing strombolian activity in the volcano's summit crater.
A flat lava dome is growing there and extruding a viscous lava flow into the open ravine to the south flank.
The slow extrusion of a lava flow from the summit crater continues and forms a dark tongue extending a few 100 meters. Rockfalls detaching from it roll frequently down the Kembar ravine on the southern flank. read all
Activity, weak during the past months, seems to have picked up. A new lava flow has started to slowly descend the southeastern slope. ... read all

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. read all
